Product details
Overview
TMPG06-12HE3/73 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 12 V breakdown voltage (VBR = 11.4–12.6 V), 400 W peak pulse power (10/1000 µs), 16.7 V maximum clamping voltage at 24.0 A peak pulse current, and AEC-Q101 qualification for under-hood automotive use.
For engineers reviewing the TMPG06-12HE3/73 datasheet, TMPG06-12HE3/73 pinout, TMPG06-12HE3/73 application, or TMPG06-12HE3/73 equivalent, key selection criteria include clamping performance at 24 A, unidirectional polarity, 185 °C max junction temperature, RoHS-compliant HE3 packaging, and compatibility with high-reliability 12 V system protection against load dump and ESD transients.
Technical Context
This TVS diode operates as a shunt-clamping device that remains high-impedance below its stand-off voltage (VWM = 10.2 V) and rapidly transitions to low-impedance conduction above its breakdown threshold. Its low incremental resistance and fast response time ensure effective suppression of sub-microsecond transients induced by inductive switching or ESD events.
The device is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine), supports continuous power dissipation of 1.0 W on an infinite heatsink, and maintains stable clamping up to 185 °C junction temperature - enabling deployment in engine control units, powertrain modules, and industrial motor drives without derating penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V - Ensures reliable triggering above 12 V nominal rail while avoiding false trips during normal operation. |
| VWM | 10.2 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA at 25 °C. |
| VC @ IPPM | 16.7 V - Clamping voltage at 24.0 A peak pulse current; defines worst-case voltage seen by protected IC/MOSFET. |
| PPPM | 400 W - Peak pulse power handling per 10/1000 µs waveform; validates capability against ISO 7637-2 Pulse 1 & 2a. |
| IFSM | 40 A - Surge current rating for 8.3 ms half-sine wave; supports protection against load-dump transients in 12 V systems. |
| TJ max | +185 °C - Enables direct mounting near heat sources (e.g., power MOSFETs, ignition coils) without thermal derating. |
| Polarity | Unidirectional - Cathode marked by color band; suitable for DC-biased rails where reverse conduction is not required. |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.115–0.125 inch lead length, 0.023–0.026 inch lead diameter, compatible with standard through-hole reflow and wave soldering (275 °C max, 10 s).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12A | Same VBR range (11.4–12.6 V), but SMB package (smaller footprint, lower IPPM = 21.2 A, PPPM = 600 W) | Lower surge current capacity; suited for space-constrained consumer PCBs, not under-hood automotive | Select SMBJ12A only when board area is critical and peak transients remain ≤21 A. |
| TPSMF12A | Same MPG06 package, but higher VC = 19.9 V at 19.7 A; lower PPPM = 200 W; no AEC-Q101 qualification | Lacks automotive qualification and thermal margin; intended for cost-sensitive industrial/commercial use | Choose TPSMF12A only for non-automotive designs where 19.9 V clamping is acceptable and 185 °C operation is unnecessary. |
Compared with SMBJ12A and TPSMF12A, the TMPG06-12HE3/73 delivers superior automotive-grade reliability, higher surge current headroom (24.0 A vs. 21.2 A or 19.7 A), tighter clamping (16.7 V), and guaranteed 185 °C operation - making it the preferred choice for mission-critical 12 V rail protection where thermal and reliability margins are non-negotiable.

FAQ
What is the maximum clamping voltage of the TMPG06-12HE3/73 at its rated peak pulse current?
The TMPG06-12HE3/73 has a maximum clamping voltage (VC) of 16.7 V at its specified peak pulse current (IPPM) of 24.0 A, measured using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during transient events. The TMPG06-12HE3/73 achieves this performance while maintaining low incremental resistance and fast response time.
Is the TMPG06-12HE3/73 qualified for automotive applications?
Yes, the TMPG06-12HE3/73 is AEC-Q101 qualified, meaning it has passed rigorous stress tests for automotive-grade reliability including temperature cycling, high-temperature reverse bias, and mechanical shock. Its 185 °C maximum junction temperature and HE3 whisker-resistant plating further validate its suitability for under-hood and powertrain applications. The TMPG06-12HE3/73 is explicitly listed in Vishay's AEC-Q101 qualified product portfolio.
What does the "HE3" suffix indicate in TMPG06-12HE3/73?
The "HE3" suffix denotes compliance with JESD 201 Class 2 whisker resistance testing and RoHS-compliant construction. It confirms the device uses matte tin-plated leads processed to prevent tin whisker growth - a critical requirement for long-term reliability in high-vibration automotive and industrial environments. The TMPG06-12HE3/73 also meets UL 94 V-0 flammability standards via its molded epoxy MPG06 package.
Can the TMPG06-12HE3/73 be used in bidirectional configurations?
No, the TMPG06-12HE3/73 is unidirectional only, with cathode identified by a color band. It conducts only during positive transients relative to its anode and cannot suppress negative-going surges on AC or bipolar signal lines. For bidirectional protection, two TMPG06-12HE3/73 devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMBJ12CA should be selected instead.
What is the standoff voltage (VWM) and why is it important for TMPG06-12HE3/73 selection?
The TMPG06-12HE3/73 has a maximum working peak reverse voltage (VWM) of 10.2 V, meaning it remains non-conductive with leakage <1 µA up to this level. This parameter ensures the device does not interfere with normal 12 V system operation while remaining ready to clamp transients exceeding ~11.4 V. Selecting a VWM ≥10 % below nominal rail voltage prevents nuisance conduction - a key design rule applied in the TMPG06-12HE3/73's specification.
