Product details
Overview
TMPG06-39AHE3/73 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 37.1 V to 41.0 V breakdown voltage (VBR), 33.3 V stand-off voltage (VWM), 53.9 V clamping voltage (VC) at 7.4 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - deployed to safeguard MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the TMPG06-39AHE3/73 datasheet, TMPG06-39AHE3/73 pinout, TMPG06-39AHE3/73 application, or TMPG06-39AHE3/73 equivalent, this page delivers verified electrical parameters, package dimensions, clamping behavior under surge conditions, thermal derating curves, and direct AEC-Q101-compliant alternatives for automotive-grade ESD and load-dump protection design.
Technical Context
This TVS diode operates as a shunt-clamping device with fast response time (<1 ns) and low incremental resistance, enabling rapid energy diversion during transient events such as ISO 7637-2 load dump or ISO 16750-2 jump-start surges. Its unidirectional polarity and 185 °C maximum junction temperature support high-reliability operation in under-hood automotive environments.
The device uses a passivated silicon junction molded in UL 94 V-0 epoxy (MPG06 package), with matte tin-plated leads compliant to J-STD-002 and JESD 22-B102 solderability standards. The HE3 suffix confirms JESD 201 Class 2 whisker resistance, critical for long-term reliability in vibration-prone systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 37.1 V / 41.0 V - Ensures reliable conduction onset above normal 33.3 V system operating voltage, preventing false triggering during ripple or tolerance drift. |
| VC @ IPPM | 53.9 V at 7.4 A - Clamps induced transients below IC absolute maximum ratings (e.g., ≤60 V for many 3.3 V/5 V interface ICs). |
| PPPM | 400 W (10/1000 µs) - Handles typical automotive load-dump energy without degradation when mounted on PCB with adequate copper area. |
| IFSM | 40 A (8.3 ms half-sine) - Withstands repetitive motor-switching surge currents common in body control modules and actuator drivers. |
| TJ max. | +185 °C - Enables placement near heat-generating components (e.g., DC-DC converters) without thermal shutdown risk. |
| VF @ 25 A | 3.5 V - Low forward voltage minimizes power loss during sustained fault conditions, reducing thermal stress during extended overvoltage events. |
| Leakage @ VWM | 1.0 µA at 33.3 V - Negligible standby current draw preserves battery life in always-on automotive subsystems (e.g., CAN wake-up receivers). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36AHE3/A | Lower VBR (36.0–40.0 V), same 400 W PPPM, SMA package (surface-mount) | Requires PCB rework for SMT layout; lacks axial lead mechanical robustness for high-vibration harness connections | Select when board space is constrained and automated assembly is preferred over through-hole mounting. |
| TPSMF36A | Same VBR range (36.0–40.0 V), 400 W rating, but SOD-123FL package with lower IPPM (7.1 A vs. 7.4 A) and higher VC (56.5 V) | Higher clamping voltage reduces margin for 5 V-tolerant interfaces; not AEC-Q101 qualified | Acceptable for cost-sensitive consumer applications where automotive qualification is unnecessary and 2.5 V extra clamping headroom is acceptable. |
Compared with SMAJ36AHE3/A and TPSMF36A, the TMPG06-39AHE3/73 provides superior mechanical stability via axial leads, guaranteed AEC-Q101 compliance, and tighter clamping (53.9 V vs. 56.5 V), making it the preferred choice for under-hood automotive power protection where vibration, temperature, and regulatory validation are critical.

FAQ
What is the breakdown voltage range for TMPG06-39AHE3/73?
The TMPG06-39AHE3/73 has a specified breakdown voltage (VBR) range of 37.1 V to 41.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent turn-on behavior across production lots and temperature extremes, directly supporting its use in 33 V nominal automotive systems where precise clamping threshold control is required. The TMPG06-39AHE3/73 maintains this specification under AEC-Q101 stress conditions.
Is TMPG06-39AHE3/73 suitable for ISO 7637-2 load dump protection?
Yes, the TMPG06-39AHE3/73 is validated for ISO 7637-2 Pulse 5a (load dump) protection due to its 400 W peak pulse power rating (10/1000 µs), 53.9 V clamping voltage at 7.4 A, and 185 °C maximum junction temperature. Its AEC-Q101 qualification confirms performance under automotive thermal and mechanical stress profiles. The TMPG06-39AHE3/73 is routinely deployed in BCM and ECU power inputs meeting this standard.
What does the "HE3" suffix indicate on TMPG06-39AHE3/73?
The "HE3" suffix on TMPG06-39AHE3/73 denotes RoHS-compliant construction, AEC-Q101 qualification, and JESD 201 Class 2 whisker resistance - confirmed by Vishay's internal testing protocol. It also specifies matte tin-plated leads meeting J-STD-002 solderability requirements. The HE3 designation is integral to the full part number and must be included for traceable procurement of the qualified variant. TMPG06-39AHE3/73 cannot be substituted with non-HE3 variants in automotive designs.
How does TMPG06-39AHE3/73 compare to bidirectional TVS diodes in sensor line protection?
The TMPG06-39AHE3/73 is unidirectional and optimized for DC-biased lines like 12 V power rails or LIN bus, where reverse conduction is not required. For AC-coupled or bidirectional signal lines (e.g., CAN), a bidirectional TVS would be necessary. The TMPG06-39AHE3/73 offers lower leakage (<1 µA) and tighter VBR tolerance than equivalent bidirectional parts, improving efficiency and precision in single-polarity applications. Its design intent excludes symmetrical clamping.
What is the maximum allowable lead temperature during soldering for TMPG06-39AHE3/73?
The TMPG06-39AHE3/73 supports solder dip at a maximum temperature of 275 °C for up to 10 seconds, per JESD 22-B106. This specification ensures compatibility with standard wave soldering processes used in automotive PCB assembly. Exceeding this limit risks epoxy cracking or junction degradation. The TMPG06-39AHE3/73 must be handled per Vishay's recommended thermal profile to maintain AEC-Q101 reliability metrics.
