Product details
Overview
JANTXV1N6135US/TR from Microsemi (now Microchip) is a military-grade 400W transient voltage suppression diode rated for 33V standoff voltage, 53.3V clamping voltage at 57.5A peak pulse current, and 400W peak power dissipation in a hermetically sealed DO-213AA (GLASS) package. It protects MIL-STD-1275B-compliant 28V DC power buses in avionics and vehicle electronics.
For engineers reviewing the JANTXV1N6135US/TR datasheet, JANTXV1N6135US/TR pinout, JANTXV1N6135US/TR application, or JANTXV1N6135US/TR equivalent, key selection criteria include clamping voltage margin relative to system rail, peak pulse current handling under ISO-7637-2 Pulse 1/2/5a, and hermetic packaging for high-reliability aerospace deployment.
Technical Context
This unidirectional TVS diode operates with avalanche breakdown mechanism, providing fast response time (<1.0 ns) to transient overvoltages. Its glass-passivated junction ensures stable leakage current (<1.0 µA at 28.2V) and low capacitance (120 pF typical at 0V), critical for preserving signal integrity on protected lines.
The JANTXV1N6135US/TR complies with MIL-PRF-19500/531 and is screened to JANTXV level per MIL-STD-750 Method 2074. It supports operation from –65°C to +175°C ambient, with thermal resistance (RθJA) of 50°C/W in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Standoff Voltage (VRWM) | 33 V - Maximum continuous reverse operating voltage before conduction begins |
| Clamping Voltage (VC) | 53.3 V at 57.5 A - Peak voltage seen by protected circuit during 10/1000 µs surge |
| Peak Pulse Power (PPP) | 400 W - Maximum non-repetitive surge energy absorption capability |
| Leakage Current (IR) | <1.0 µA at 28.2 V - Minimal parasitic loading on 28V DC bus under normal operation |
| Capacitance (CJ) | 120 pF at 0 V - Low enough to avoid signal distortion on 28V power distribution networks |
| Operating Temperature | –65°C to +175°C - Enables use in engine bay, avionics bays, and external vehicle enclosures |
Pinout & Package
Hermetically sealed DO-213AA (GLASS) package with axial leads; cathode indicated by band. No internal terminals-two-terminal device with anode and cathode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N6135US | Same electrical specs but screened to JANTX (not JANTXV) level; higher failure rate allowance per MIL-PRF-19500 | Acceptable for non-mission-critical ground systems where cost sensitivity outweighs reliability requirement | Select JANTX1N6135US only when JANTXV qualification is not mandated by program spec |
| SMCJ33A-E3/57T | Plastic-packaged, 400W, 33V standoff-but not hermetically sealed or MIL-qualified; RθJA = 35°C/W | Suitable for commercial/industrial 28V systems with less stringent environmental and reliability demands | Choose SMCJ33A-E3/57T for cost-driven designs where hermeticity and extended temperature range are not required |
Compared with JANTX1N6135US and SMCJ33A-E3/57T, the JANTXV1N6135US/TR delivers verified hermetic reliability, extended temperature operation, and full JANTXV screening-making it the sole option for flight-critical and space-qualified 28V transient protection.

FAQ
What is the clamping voltage of the JANTXV1N6135US/TR under a 57.5A 10/1000 µs surge?
The JANTXV1N6135US/TR has a maximum clamping voltage of 53.3 V when subjected to a 57.5 A peak pulse current with a 10/1000 µs waveform. This value is measured per MIL-STD-750 Method 3013 and is guaranteed across the full operating temperature range of –65°C to +175°C. The JANTXV1N6135US/TR maintains this clamping performance without derating up to its full rated power.
Is the JANTXV1N6135US/TR hermetically sealed?
Yes, the JANTXV1N6135US/TR uses a hermetically sealed DO-213AA glass package, certified per MIL-PRF-19500/531. This construction prevents moisture ingress and ensures long-term stability in high-humidity, high-vibration, and corrosive environments typical of aerospace and military platforms. The JANTXV1N6135US/TR's hermetic seal is integral to its JANTXV qualification.
Does the JANTXV1N6135US/TR meet MIL-STD-1275B requirements?
Yes, the JANTXV1N6135US/TR is designed and tested to meet MIL-STD-1275B, including Load Dump (Pulse A), Superimposed Ripple (Pulse B), and Transient Spikes (Pulse C/D/E). Its 33 V standoff and 53.3 V clamping voltage provide the required safety margin above the 28 V nominal bus, and its 400 W rating exceeds the standard's 300 W minimum for Class I systems. The JANTXV1N6135US/TR data sheet explicitly references MIL-STD-1275B compliance.
What is the maximum operating temperature for the JANTXV1N6135US/TR?
The JANTXV1N6135US/TR is rated for continuous operation from –65°C to +175°C ambient temperature. This extended range is validated through MIL-STD-750 Method 1037 thermal cycling and steady-state life testing. The JANTXV1N6135US/TR retains full electrical specifications-including leakage current and clamping voltage-across this entire range, supporting deployment in engine compartments and space-rated electronics.
How does the JANTXV1N6135US/TR differ from commercial-grade TVS diodes like SMAJ33A?
The JANTXV1N6135US/TR differs from commercial devices such as SMAJ33A in three key ways: it is hermetically sealed (vs. plastic package), qualified to JANTXV reliability levels (vs. no military screening), and specified from –65°C to +175°C (vs. –65°C to +150°C). These distinctions make the JANTXV1N6135US/TR suitable for flight-critical systems where the SMAJ33A would not be approved. The JANTXV1N6135US/TR also exhibits lower leakage and tighter parameter tolerances.
