Product details
Overview
TMPG06-20HE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails and signal lines. It features a 19.0 V to 21.0 V breakdown voltage (VBR), 17.0 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 14.4 A peak pulse current (IPPM), and clamps to ≤27.7 V at rated surge - deployed on engine control units, sensor interfaces, and 12 V DC bus lines.
For engineers reviewing the TMPG06-20HE3/73 datasheet, TMPG06-20HE3/73 pinout, TMPG06-20HE3/73 application, or TMPG06-20HE3/73 equivalent, key selection criteria include AEC-Q101 qualification, 185 °C max junction temperature, low incremental resistance, fast response time, and compatibility with high-reliability automotive PCB layouts requiring RoHS-compliant, whisker-tested terminations.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating above its 17.0 V stand-off voltage to divert transient energy away from sensitive components. Its silicon avalanche structure delivers sub-nanosecond response and stable clamping performance across -65 °C to +185 °C operating range.
The MPG06 package supports high thermal reliability under repetitive surge conditions, with 1.0 W steady-state power dissipation and 40 A non-repetitive forward surge rating (8.3 ms half-sine). It meets JESD 201 Class 2 whisker resistance and JESD 22-B106 solder dip requirements (275 °C, 10 s).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.0 V / 21.0 V - defines precise avalanche initiation threshold for repeatable clamping onset |
| VWM | 17.0 V - maximum continuous reverse voltage before leakage exceeds 1 μA, ensuring no false triggering |
| IPPM | 14.4 A - peak surge current it safely clamps at 10/1000 µs waveform without degradation |
| VC | ≤27.7 V - clamped voltage at IPPM, limiting stress on downstream ICs during transients |
| PPPM | 400 W - peak pulse power handling capability under standardized surge test conditions |
| TJ max. | +185 °C - enables operation in under-hood automotive environments without derating loss |
| Polarity | Unidirectional - protects against positive-going transients only; cathode marked by band |
Pinout & Package

Applications
| Automotive Engine Control Unit (ECU) | Industrial CAN Bus Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | Same VWM (17.1 V), lower PPPM (400 W same), but SMA package (smaller footprint, lower thermal mass) | Limited to lower ambient temperatures due to 150 °C TJ max and no AEC-Q101 qualification | Select when board space is constrained and automotive qualification is not required |
| TPSMF20A | Same VWM (17.0 V), identical AEC-Q101 qualification, but SOD-123FL package with 1.5 mm lead spacing | Higher mounting density possible, but lower IFSM (30 A vs. 40 A) limits use in high-inductance motor circuits | Select for compact surface-mount designs where 30 A surge margin suffices |
Compared with SMAJ20A and TPSMF20A, the TMPG06-20HE3/73 provides superior thermal robustness (185 °C TJ max), higher surge current endurance (40 A IFSM), and axial-leaded mechanical stability ideal for high-vibration under-hood placements - making it the preferred choice for mission-critical automotive power rail protection.

FAQ
What is the breakdown voltage tolerance for TMPG06-20HE3/73?
The TMPG06-20HE3/73 has a specified breakdown voltage (VBR) range of 19.0 V to 21.0 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 20 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable design margining in safety-critical automotive systems where predictable overvoltage response is mandatory.
Is TMPG06-20HE3/73 suitable for bidirectional transient protection?
No, TMPG06-20HE3/73 is unidirectional only, as confirmed in the Vishay datasheet. It protects against positive transients on the cathode side relative to anode (ground). For bidirectional protection - such as AC lines or differential buses exposed to both polarities - a dedicated bidirectional TVS like SMBJ20CA or a back-to-back configuration would be required. Using TMPG06-20HE3/73 in reverse-biased mode risks permanent breakdown.
Does TMPG06-20HE3/73 meet automotive qualification standards?
Yes, TMPG06-20HE3/73 is explicitly AEC-Q101 qualified per the Vishay datasheet (Document Number 88404, Revision 17-Sep-2021). This includes stress testing for high-temperature reverse bias, temperature cycling, humidity bias, and mechanical shock - validating its suitability for under-hood and powertrain applications where long-term reliability under thermal and vibration stress is essential.
What is the maximum clamping voltage of TMPG06-20HE3/73 at rated surge current?
The maximum clamping voltage (VC) of TMPG06-20HE3/73 is 27.7 V at its rated peak pulse current (IPPM) of 14.4 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected downstream components experience no more than 27.7 V during worst-case surge events - critical for safeguarding 3.3 V or 5 V logic supplies and interface ICs.
How does the MPG06 package of TMPG06-20HE3/73 support high-reliability mounting?
The MPG06 package of TMPG06-20HE3/73 features matte tin-plated axial leads compliant with J-STD-002 and JESD 22-B102, plus JESD 201 Class 2 whisker resistance. Its 0.100" (2.54 mm) lead pitch and molded UL 94 V-0 epoxy body provide mechanical stability under thermal cycling and vibration - enabling secure through-hole mounting in automotive ECUs and industrial controllers where solder joint integrity is non-negotiable.
