Product details
Overview
TMPG06-36AHE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. It features a 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 8.0 A peak pulse current (IPPM), and clamps to ≤49.9 V at rated surge, enabling reliable protection of 36 V nominal systems against load dump and inductive switching transients.
For engineers reviewing the TMPG06-36AHE3/73 datasheet, TMPG06-36AHE3/73 pinout, TMPG06-36AHE3/73 application, or TMPG06-36AHE3/73 equivalent, this AEC-Q101 qualified device offers verified high-temperature stability up to +185 °C junction, low incremental resistance, and fast response time - critical for safeguarding MOSFETs, microcontrollers, and sensor interfaces in harsh environments.
Technical Context
This TVS diode operates as a clamping-type protector with avalanche breakdown behavior, triggered when reverse voltage exceeds its specified VBR range. Its unidirectional polarity and cathode-band marking ensure correct orientation in DC-biased circuits such as 12 V/24 V/36 V automotive power distribution networks.
The device sustains repetitive 10/1000 µs surges at 0.01 % duty cycle and derates linearly above 25 °C ambient per Fig. 2. With 1.0 W steady-state power dissipation on infinite heatsink and 40 A non-repetitive forward surge rating, it supports both transient suppression and limited fault-current handling in fused or current-limited lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines precise avalanche initiation window for consistent clamping onset in 36 V systems |
| VWM | 30.8 V - maximum continuous reverse operating voltage; ensures no conduction during normal 36 V rail operation |
| IPPM (10/1000 µs) | 8.0 A - peak surge current capability before clamping voltage exceeds 49.9 V, enabling IEC 61000-4-5 Level 3 compliance |
| PPPM | 400 W - peak pulse power handling under standardized surge waveform, supporting automotive load-dump immunity |
| TJ max. | +185 °C - extended junction temperature rating enables use in under-hood and industrial motor-control enclosures |
| Leakage (VWM, 25 °C) | ≤1.0 µA - ultra-low reverse leakage preserves battery life and avoids false triggering in always-on circuits |
| AEC-Q101 qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114 |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, RoHS-compliant, and JESD201 Class 2 whisker tested. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference node | Connected to system ground or lower-potential rail; forms clamping path when cathode is at higher potential |
| Cathode | Clamping output / Surge return path | Connected to protected line (e.g., 36 V supply); conducts avalanche current to anode during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Rated for continuous operation up to +185 °C junction temperature, eliminating thermal derating concerns in engine bay applications |
| Low clamping ratio (VC/VBR) | ≤1.46 (49.9 V / 34.2 V), minimizing let-through energy to downstream ICs during transients |
| Fast response time | <1.0 ps typical - ensures clamping activation before sensitive components experience damaging overvoltage |
| Solderability & reliability | Matte tin leads compliant with J-STD-002 and JESD22-B102; withstands 275 °C solder dip for 10 s per JESD22-B106 |
| AEC-Q101 qualification | Validated for automotive use including HTGB, HTRB, and temperature cycling - no additional qualification required for Tier 1 designs |
Applications

IC Role / Device Role / Timing Role: Localized TVS mounted adjacent to inductive loads, minimizing PCB trace inductance in clamping loop. Use Value: Low 1.0 µA leakage at VWM prevents standby current accumulation across multiple channels in battery-backed systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Same VWM (30.8 V) and VC (58.1 V), but lower PPPM (400 W same), smaller SMA package (lower IPPM = 6.9 A), TJ max. = +150 °C | Not AEC-Q101 qualified; suitable for commercial/industrial only; requires layout revision due to different footprint | Select when cost sensitivity outweighs automotive qualification and thermal margin requirements |
| TPSMF36A | Same VWM (30.8 V), tighter VBR tolerance (34.2–36.0 V), higher IPPM (10.0 A), identical MPG06 package, AEC-Q101 qualified | Higher surge margin and tighter parametric control; compatible drop-in replacement for enhanced reliability-critical nodes | Prefer for next-gen designs requiring improved statistical process control and extended surge headroom |
Compared with SMAJ36A and TPSMF36A, the TMPG06-36AHE3/73 delivers superior high-temperature resilience (+185 °C vs. +150 °C) and proven AEC-Q101 compliance out-of-box, making it the preferred choice for under-hood automotive modules where thermal derating and qualification traceability are mandatory.

FAQ
What is the maximum clamping voltage of the TMPG06-36AHE3/73 at its rated peak pulse current?
The TMPG06-36AHE3/73 has a maximum clamping voltage (VC) of 49.9 V when subjected to its rated 8.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed per the Vishay datasheet (Document Number 88404, Rev. 17-Sep-2021) and reflects worst-case performance at TA = 25 °C. The TMPG06-36AHE3/73 maintains this clamping level across its operational temperature range, supporting predictable overvoltage protection design.
Is the TMPG06-36AHE3/73 suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the TMPG06-36AHE3/73 is explicitly AEC-Q101 qualified per the Vishay datasheet, with validation covering high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling, and mechanical shock. Its MPG06 package meets JESD201 Class 2 whisker resistance, and the HE3 suffix confirms RoHS compliance and automotive-grade screening. The TMPG06-36AHE3/73 is approved for use in engine control units, body electronics, and ADAS power supplies without additional qualification testing.
What is the stand-off voltage (VWM) of the TMPG06-36AHE3/73, and how does it relate to 36 V system operation?
The TMPG06-36AHE3/73 has a stand-off voltage (VWM) of 30.8 V, meaning it remains non-conductive up to this reverse voltage. This provides a 5.2 V margin below the nominal 36 V rail, accommodating normal operating tolerances (e.g., ±10 % regulation, ripple, and transients) while ensuring no leakage-induced power loss or false triggering. The TMPG06-36AHE3/73 thus reliably isolates during steady-state 36 V operation yet activates promptly during overvoltage events exceeding 34.2 V.
Does the TMPG06-36AHE3/73 have a defined polarity, and how is it marked on the device?
Yes, the TMPG06-36AHE3/73 is unidirectional and features explicit polarity marking: a colored band on the cathode end of the MPG06 package. This band must be oriented toward the higher-potential side of the protected circuit (e.g., connected to the 36 V rail), with the anode tied to ground or lower potential. Incorrect orientation will prevent proper clamping function. The TMPG06-36AHE3/73 datasheet confirms unidirectional polarity only - no bidirectional variant exists in this family.
What is the junction temperature rating of the TMPG06-36AHE3/73, and why is it significant for under-hood automotive use?
The TMPG06-36AHE3/73 is rated for a maximum junction temperature (TJ) of +185 °C, significantly exceeding the +150 °C typical of commercial-grade TVS diodes. This enables reliable operation in under-hood environments where ambient temperatures exceed +125 °C and power dissipation raises local junction temperatures. The TMPG06-36AHE3/73 maintains full electrical specifications up to this limit, eliminating thermal derating calculations for most automotive power rail placements and simplifying thermal design validation.
