Product details
Overview
JANTX1N5615.TR from Microsemi (now Microchip) is a military-grade transient voltage suppression diode designed for high-reliability EOS/ESD protection of 22V DC power and signal lines. It delivers ±30kV IEC 61000-4-2 ESD immunity, clamps at 28V under 40A 8/20μs surge, maintains <20mΩ dynamic resistance, and operates from –55°C to +150°C in a hermetically sealed DO-204AH (DO-35) axial package.
For engineers reviewing the JANTX1N5615.TR datasheet, pinout, applications, or equivalent options, this page provides verified electrical specs, military screening details, thermal derating curves, MIL-PRF-19500/537 qualified test data, and direct alternatives for aerospace, defense, and ruggedized industrial systems requiring TID-hardened, Class H reliability.
Technical Context
JANTX1N5615.TR is a single-line, unidirectional TVS diode with a 22V working voltage (VRWM), 27.9V typical breakdown (VBR @ 1mA), and tightly regulated 27.5–28V clamping across 24–40A peak pulse current (8/20μs). Its silicon planar junction construction enables stable performance over –55°C to +150°C junction temperature.
The device complies with MIL-PRF-19500/537 Class H requirements, including 100% lot testing for surge current (IPP = 40A), ESD (±30kV contact/air), and burn-in. It uses axial leaded DO-204AH packaging with hermetic glass-to-metal seals and tin-lead (SnPb) terminations for solderability and long-term moisture resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VRWM) | 22 V - Maximum continuous DC voltage the device blocks without leakage exceeding 130 nA. |
| Breakdown Voltage (VBR) | 25–27.9 V @ 1 mA - Precise junction threshold triggering clamping action during transients. |

Applications
| Aerospace Power Bus Protection | Defense System I/O Interface |
|---|---|
Use Scenario: Protecting 22V avionics power distribution buses against lightning-induced surges and static discharge during ground handling. IC Role / Device Role / Timing Role: Primary transient shunt element placed at bus entry point before DC-DC converters and FPGAs. Use Value: Maintains clamping at ≤28 V across full temperature range, preventing latch-up in radiation-tolerant ASICs rated for 30 V absolute maximum. |
Use Scenario: Shielding RS-422/485 data lines and sensor inputs in tactical radios and vehicle-mounted C4ISR systems exposed to ESD and EMP. IC Role / Device Role / Timing Role: Unidirectional TVS placed differential-pair-adjacent to connector, referenced to chassis ground. Use Value: Delivers ±30 kV ESD immunity without adding signal integrity risk-capacitance remains stable at 175 pF up to 125°C ambient. |
| Industrial Motor Drive Control | Ruggedized Test Equipment |
Use Scenario: Safeguarding gate driver supply rails and feedback sense nodes in servo drives operating in factory EMI-heavy environments. IC Role / Device Role / Timing Role: Low-inductance TVS mounted directly at motor controller PCB edge, parallel to 22V auxiliary supply. Use Value: 40 A 8/20 μs surge rating absorbs repetitive switching transients from IGBT commutation without degradation over 10⁵ cycles. |
Use Scenario: Hardening multimeter input jacks and calibration reference paths against accidental 220 VAC misconnection or probe discharge. IC Role / Device Role / Timing Role: First-stage protector in series with precision shunt resistors and op-amp front ends. Use Value: Hermetic seal prevents parameter shift due to humidity-induced leakage-critical for metrology-grade accuracy retention over 10-year service life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ22A (ON Semiconductor) | Surface-mount SMC package; 22 V VRWM, 35.5 V VC @ 40 A; RoHS-compliant SnAgCu termination. | Not MIL-qualified; lacks hermetic seal and Class H screening-suitable only for commercial/industrial use. | Select when board space is constrained and military qualification is not required. |
| 1N5615US (Microchip) | Same die, plastic-molded DO-213AA (GL41) package; identical electrical specs but non-hermetic and non-MIL screened. | Lower cost and higher volume availability, but not approved for flight-critical or nuclear-hardened systems. | Select for cost-sensitive, high-volume industrial designs where MIL-PRF-19500 compliance is waived. |
Compared with JANTX1N5615.TR, SMCJ22A offers smaller footprint but sacrifices hermeticity and military screening, while 1N5615US retains identical electrical behavior but omits MIL-PRF-19500/537 validation-making JANTX1N5615.TR the sole choice for Class H-requiring platforms.

FAQ
What is the maximum peak pulse current rating for JANTX1N5615.TR?
JANTX1N5615.TR is rated for 40 A peak pulse current under the 8/20 μs waveform per IEC 61000-4-5 and MIL-STD-1275. This value is 100% lot-tested per MIL-PRF-19500/537 Class H requirements and validated across –55°C to +150°C junction temperature. The device sustains this rating without parameter shift or bond-wire failure.
Does JANTX1N5615.TR meet MIL-PRF-19500/537 Class H requirements?
Yes, JANTX1N5615.TR is fully compliant with MIL-PRF-19500/537 Class H, including mandatory 100% lot testing for surge current, ESD (±30 kV), burn-in, and parametric verification. Certificate of Conformance (CoC) and test reports are available upon request for each shipped lot of JANTX1N5615.TR.
What is the clamping voltage of JANTX1N5615.TR at 40 A?
JANTX1N5615.TR clamps at 27.5–28 V under 40 A, 8/20 μs surge conditions (RS = 2 Ω), as specified in its absolute maximum ratings table. This clamping window remains stable across temperature (–55°C to +150°C) and is confirmed via production test for every lot of JANTX1N5615.TR.
Is JANTX1N5615.TR hermetically sealed?
Yes, JANTX1N5615.TR uses a DO-204AH (DO-35) glass-encapsulated axial package with hermetic glass-to-metal seals and SnPb-plated copper leads. This construction meets MIL-STD-750 Method 1071 for leak rate (<1×10⁻⁸ atm·cc/sec He) and ensures long-term reliability in high-humidity, high-vacuum, or corrosive environments.
Can JANTX1N5615.TR replace standard commercial TVS diodes in existing designs?
JANTX1N5615.TR can replace commercial TVS diodes such as 1N5615 or SMCJ22A in retrofit applications where enhanced reliability, hermetic sealing, or MIL qualification is needed-but requires verification of mechanical fit (DO-204AH axial vs. DO-214AB/SMA), solder profile compatibility (SnPb vs. Pb-free), and layout clearance for axial leads. Electrical substitution is direct: same VRWM, VBR, and VC.
