Product details
Overview
JANTX1N5636A from Microchip Technology is a hermetically sealed, unidirectional Transient Voltage Suppressor (TVS) diode in DO-13 metal package, designed for high-reliability aerospace and military systems. It features 11.1 V rated standoff voltage (VWM), 12.4 V minimum breakdown voltage (V(BR)), and clamps transients to ≤18.2 V at 82 A peak pulse current (IPP), delivering 1500 W peak pulse power for 10/1000 µs waveforms.
For engineers reviewing the JANTX1N5636A datasheet, JANTX1N5636A pinout, JANTX1N5636A application, or JANTX1N5636A equivalent, key selection criteria include its MIL-PRF-19500/500 qualified JANTX-level screening, −55 °C to +175 °C operating temperature range, sub-100 ps response time, and IEC61000-4-5 Class 4 secondary lightning protection capability with 2 Ω source impedance.
Technical Context
The JANTX1N5636A operates as a unidirectional avalanche-clamping TVS diode, activated only under reverse-biased transient overvoltage conditions above its 12.4 V (min) breakdown threshold. Its hermetic DO-13 metal-glass package ensures long-term reliability in harsh environments including avionics and ground-based military electronics.
It delivers 1500 W peak pulse power per 10/1000 µs waveform at 25 °C lead temperature, with thermal resistance of 50 °C/W junction-to-lead and 110 °C/W junction-to-ambient on FR4. Clamping occurs at ≤18.2 V when subjected to 82 A IPP, enabling robust protection of downstream 12 V rail circuitry without sustained conduction.

FAQ
What is the rated standoff voltage (VWM) of the JANTX1N5636A?
The JANTX1N5636A has a rated standoff voltage (VWM) of 11.1 V, meaning it remains nonconductive with ≤5 µA leakage current up to this reverse voltage. This value is selected to provide sufficient margin above nominal 12 V system rails while ensuring reliable clamping onset during transients. The JANTX1N5636A is specified per MIL-PRF-19500/500 and tested across −55 °C to +175 °C.
Does the JANTX1N5636A meet IEC61000-4-5 Class 4 requirements?
Yes, the JANTX1N5636A is validated for IEC61000-4-5 Class 4 secondary lightning protection when tested with a 2 Ω source impedance. Its 1500 W peak pulse power rating and ≤18.2 V clamping voltage at 82 A IPP ensure compliance under the standard's 4 kV open-circuit test waveform. The JANTX1N5636A achieves this performance in its hermetic DO-13 package without derating.
What is the thermal resistance specification for the JANTX1N5636A?
The JANTX1N5636A has a thermal resistance of 50 °C/W junction-to-lead when measured at 10 mm from the case, and 110 °C/W junction-to-ambient on FR4 board with 4 mm² copper pads and 1 mm wide × 25 mm long traces. These values are critical for calculating safe surge repetition rates and verifying thermal safety margins in high-density layouts. The JANTX1N5636A's metal package enables superior heat dissipation versus plastic alternatives.
How does the JANTX1N5636A differ from commercial-grade 1N5636A?
The JANTX1N5636A undergoes full MIL-PRF-19500/500 screening-including temperature cycling, burn-in, and hermeticity testing-while the commercial 1N5636A does not. Electrical parameters are identical, but JANTX-level parts guarantee performance across −55 °C to +175 °C and include lot traceability, radiation hardness per MicroNote 050, and extended reliability data. The JANTX1N5636A is intended for mission-critical avionics and defense platforms.
What is the maximum peak pulse current (IPP) rating for the JANTX1N5636A?
The JANTX1N5636A is rated for a maximum peak pulse current (IPP) of 82 A under the standard 10/1000 µs exponential waveform at 25 °C lead temperature. This corresponds to its 1500 W peak pulse power rating when clamped to ≤18.2 V. Derating applies above 25 °C per Figure 4 in the datasheet, and the JANTX1N5636A maintains full rating up to TL = 125 °C with appropriate PCB layout.
