Product details
Overview
JANTX1N5653A 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 a 55.1 V rated standoff voltage (VWM), 61.2–74.8 V breakdown voltage (V(BR)) at 1 mA, 98.0 V maximum clamping voltage (VC) at 15.3 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the JANTX1N5653A datasheet, JANTX1N5653A pinout, JANTX1N5653A application, or JANTX1N5653A equivalent, this part delivers sub-100 ps response time, -55°C to +175°C operating temperature range, and MIL-PRF-19500/500 JANTX qualification - critical for avionics surge protection, secondary lightning compliance (IEC61000-4-5), and ESD/EFT hardening per IEC61000-4-2/-4-4.
Technical Context
The JANTX1N5653A operates as a unidirectional avalanche diode, entering controlled breakdown when reverse voltage exceeds its V(BR) threshold, clamping transients to ≤98.0 V while sustaining 15.3 A peak pulse current. Its hermetic DO-13 metal-glass package ensures stable thermal resistance (50°C/W junction-to-lead) and radiation hardness per MicroNote 050.
It is rated for 1500 W non-repetitive peak pulse power at TL = 25°C with ≤0.01% duty cycle, supports forward surge current up to 200 A (8.3 ms half-sine), and exhibits a +0.104%/°C temperature coefficient of V(BR), enabling predictable voltage drift across extended temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff Voltage) | 55.1 V - Maximum continuous reverse voltage before leakage exceeds 5 µA; sets system operating margin against false triggering. |
| V(BR) @ I(BR) | 61.2–74.8 V @ 1 mA - Breakdown onset range defining minimum and maximum avalanche initiation voltage under test conditions. |
| VC @ IPP | 98.0 V @ 15.3 A - Clamped voltage during worst-case 10/1000 µs surge; determines protected circuit's maximum transient overvoltage exposure. |
| PPP (Peak Pulse Power) | 1500 W - Sustained energy absorption capability for short-duration surges; enables robust protection in inductive switching environments. |
| Response Time | <100 ps - Near-instantaneous avalanche turn-on; ensures effective suppression of ESD events and fast-rising RF-induced transients. |

|---|---|
Use Scenario: Protecting ARINC 429 data lines and sensor inputs in airborne flight control computers from secondary lightning-induced surges (IEC61000-4-5, 42 Ω source). IC Role / Device Role / Timing Role: Unidirectional transient clamp placed between signal line and chassis ground, absorbing energy before it reaches FPGA I/O or ADC front-end. Use Value: Maintains signal integrity under 15.3 A surge events while limiting clamped voltage to 98.0 V - below absolute maximum ratings of downstream 100 V-tolerant interface ICs. |
Use Scenario: Safeguarding gate drivers and feedback sensors in variable-frequency drives exposed to inductive kickback from 480 VAC motors. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC bus monitoring lines and isolated encoder supply rails, triggered within <100 ps of transient onset. Use Value: Prevents latch-up or permanent damage in optocouplers and isolated amplifiers by clamping transients to ≤98.0 V before they exceed 100 V isolation barrier ratings. |
| Military Vehicle Power Systems | High-Reliability Test Equipment |
Use Scenario: Suppressing load dump and alternator ripple transients in 28 VDC vehicle electronics per MIL-STD-1275E. IC Role / Device Role / Timing Role: Front-end protection device on main power input rail, mounted directly to chassis for lowest possible inductance path to ground. Use Value: Withstands 200 A forward surge (8.3 ms) and clamps 1500 W pulses without parameter shift - ensuring uninterrupted operation during engine start-stop cycles. |
Use Scenario: Shielding precision analog measurement circuits in automated test equipment from ESD events during probe contact and cable handling. IC Role / Device Role / Timing Role: Localized TVS on ±15 V op-amp supply rails and low-level signal paths, leveraging sub-100 ps response to prevent latch-up in rail-to-rail input stages. Use Value: Limits ESD-induced voltage overshoot to ≤98.0 V, keeping transient stress well below the 105 V absolute maximum rating of high-precision instrumentation amplifiers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5653A (commercial grade) | No MIL-PRF-19500/500 screening; same electrical specs and DO-13 package. | Lacks JANTX-level burn-in, lot traceability, and radiation hardness validation. | Select for cost-sensitive ground-based industrial systems where military qualification is not mandated. |
| JANTXV1N5653A | Higher screening level (JANTXV) with extended temperature testing (-65°C to +175°C) and tighter parametric limits. | Required for spaceflight, nuclear-hardened, or mission-critical platforms demanding zero latent defects. | Choose when full JANTXV qualification, including enhanced lot acceptance testing, is specified in system requirements. |
Compared with JANTX1N5653A, the commercial 1N5653A offers identical clamping performance at lower cost but no military screening, while JANTXV1N5653A adds extreme-temperature validation and tighter process controls - making JANTX1N5653A the balanced choice for certified avionics and defense electronics requiring proven reliability without JANTXV overhead.

FAQ
What is the clamping voltage of JANTX1N5653A under a 10/1000 µs surge?
The JANTX1N5653A has a maximum clamping voltage (VC) of 98.0 V when subjected to its rated peak pulse current of 15.3 A under a 10/1000 µs waveform. This value is measured at 25°C ambient and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream components remain within their absolute maximum voltage ratings. The JANTX1N5653A maintains this clamping performance across its full military temperature range.
Is JANTX1N5653A suitable for bidirectional transient protection?
No, JANTX1N5653A is a unidirectional TVS diode optimized for clamping reverse-polarity transients only. Its design assumes the anode is referenced to ground or a stable low-impedance node, with the cathode connected to the protected line. For bidirectional protection - such as AC signal lines or floating buses - Microchip's 1N6036–1N6072A series in the same DO-13 package is specified. Using JANTX1N5653A in bidirectional configurations risks forward conduction failure or inadequate positive-going transient suppression.
What is the thermal resistance specification for JANTX1N5653A?
JANTX1N5653A has a junction-to-lead thermal resistance (RθJL) of 50°C/W when measured at 0.375 inches (10 mm) from the case body, per MIL-STD-750 Test Method 1071. This value assumes proper mechanical mounting to a thermally conductive surface - essential for dissipating energy during repetitive surges. When mounted on FR4 PCB with 4 mm² copper pads, its junction-to-ambient resistance rises to 110°C/W, so board-level thermal design must account for this derating to avoid exceeding the +175°C maximum junction temperature.
Does JANTX1N5653A meet IEC61000-4-5 for secondary lightning protection?
Yes, JANTX1N5653A is validated for secondary lightning protection per IEC61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances across multiple test classes. Specifically, it supports Class 1–4 protection with 42 Ω source (up to 1N5655A), Class 1–3 with 12 Ω (up to 1N5651A), and Class 2–3 with 2 Ω (up to 1N5643A). Its 1500 W peak pulse rating and sub-100 ps response ensure compliance in real-world surge waveforms encountered in aircraft wiring harnesses and vehicle power distribution networks.
How does the JANTX qualification differ from commercial 1N5653A?
JANTX1N5653A undergoes full MIL-PRF-19500/500 screening - including extended temperature cycling, burn-in, and lot traceability - whereas commercial 1N5653A meets only JEDEC specifications. Both share identical electrical parameters and DO-13 packaging, but JANTX1N5653A adds guaranteed radiation hardness (per MicroNote 050), tighter parametric limits, and documentation required for DoD contracts. The JANTX1N5653A is the only version approved for use in flight-certified avionics hardware.
