2N6804JANTX

Updated: 2026-09-19

Overview

The 2N6804JANTX is a military-qualified silicon-controlled rectifier (SCR) meeting stringent MIL-PRF-19500/540 standards. Manufactured for high-reliability applications, it is commonly used in aerospace, defense, and industrial systems where component failure is not an option. As part of the JANTX series, this device undergoes rigorous testing for thermal cycling, mechanical shock, and hermeticity. Its design ensures consistent performance in extreme temperatures (-65°C to +150°C) and harsh environments, making it a preferred choice for mission-critical circuits.

Structure and Working Principle

The 2N6804JANTX features a four-layer (PNPN) silicon structure with anode, cathode, and gate terminals. When a positive gate current triggers the device, it latches into conduction until the anode current drops below the holding threshold. Key structural elements include a gold-doped silicon wafer for improved switching characteristics and a ceramic/metal hermetic package that prevents moisture ingress. The device's surge current rating (typically 100-200A) and blocking voltage (up to 400V) are optimized for transient suppression and power control applications.

Key Features

Military-grade reliability is the standout feature, with JANTX certification ensuring compliance with MIL-STD-750 test methods. The device offers a high repetitive peak off-state voltage (VDRM) of 200-400V and surge current (ITS) capabilities exceeding 100A. Other notable characteristics include low gate trigger current (5-15mA), fast switching speed (<5μs), and a wide operating temperature range. The hermetic TO-39 package provides excellent thermal conductivity and mechanical durability, critical for aerospace applications.

Application Areas

Primary applications include power conditioning systems in satellites, avionics power distribution, and military radar equipment. Its ability to handle high surge currents makes it ideal for crowbar circuits in power supplies and voltage regulators. Industrial uses encompass motor control, uninterruptible power supplies (UPS), and welding equipment. In commercial aviation, the 2N6804JANTX is often specified for engine control systems and auxiliary power units (APUs) due to its proven reliability record.

Maintenance and Precautions

Proper heat sinking is essential—case temperature should not exceed 150°C during operation. Use thermal interface materials to minimize thermal resistance when mounting to heatsinks. Avoid exceeding maximum ratings (dV/dt, di/dt) to prevent unintended triggering or device failure. For long-term storage, maintain conditions per MIL-STD-1835 (typically <40°C, <90% RH non-condensing). Periodic electrical testing is recommended for shelf-life extension programs.

B2B Procurement Guide

When sourcing the 2N6804JANTX, verify supplier certifications (QML-38535 preferred) and request full traceability documentation. Lead times can extend to 16-20 weeks for military-spec units. Consider alternative JAN/JANTXV versions for non-critical applications to reduce costs. For prototype quantities, authorized distributors like Arrow Electronics or Avnet often stock limited quantities. Bulk purchases (100+ units) may qualify for negotiated pricing from manufacturers like Microsemi (now Microchip Technology).
