Product details
Overview
TMPG06-43AHE3_A/B 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 400 W peak pulse power rating (10/1000 µs), 40.9–45.2 V breakdown voltage, 36.8 V stand-off voltage, 59.3 V clamping voltage at 6.7 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TMPG06-43AHE3_A/B datasheet, TMPG06-43AHE3_A/B pinout, TMPG06-43AHE3_A/B application, or TMPG06-43AHE3_A/B equivalent, key selection criteria include clamping performance under 10/1000 µs transients, high-temperature junction stability up to +185 °C, unidirectional polarity enforcement via cathode band, and RoHS-compliant matte tin-plated leads meeting J-STD-002 solderability.
Technical Context
This TVS diode operates as a shunt-clamping device that remains non-conductive below its stand-off voltage (VWM = 36.8 V) and rapidly transitions to low-impedance conduction above its breakdown threshold (VBR = 40.9–45.2 V). Its response time is sub-nanosecond, enabling effective suppression of fast-rising ESD and inductive switching transients.
The device uses a passivated silicon junction encapsulated in UL 94 V-0 epoxy (MPG06 package), with thermal derating defined per Fig. 2 and Fig. 5 - maintaining 1.0 W power dissipation at TL = 75 °C and supporting repetitive surge duty cycles up to 0.01 % at TA = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 400 W - sustains single high-energy transients without failure, e.g., ISO 7637-2 Pulse 1/2a/5a in automotive ECUs |
| Breakdown Voltage VBR | 40.9–45.2 V at 1 mA - defines precise clamping onset; ensures reliable turn-on before downstream IC damage thresholds |
| Stand-off Voltage VWM | 36.8 V - maximum continuous reverse voltage before leakage exceeds 1 µA; sets safe operating margin vs. 36 V nominal rail |
| Clamping Voltage VC | 59.3 V at IPPM = 6.7 A - actual voltage seen by protected circuit during worst-case surge; critical for MOSFET gate oxide safety |
| Operating Junction Temp | −65 °C to +185 °C - enables use in under-hood automotive environments and high-ambient industrial enclosures |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
| Package | MPG06 - axial-leaded, 2.54 mm lead spacing, UL 94 V-0 molded epoxy housing with cathode band marking |
Pinout & Package
MPG06 is an axial-leaded, through-hole package with two terminals: anode and cathode. The cathode is marked by a color band on the body. Leads are matte tin-plated and solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to ground or lower-potential node in unidirectional TVS configuration | Provides reference path for clamping; must be routed with low-inductance connection to minimize overshoot during surge |
| Cathode | Current exit point in forward bias; connected to protected line (e.g., 36 V supply rail or CAN-H) | Marked by color band; determines polarity orientation - reversal causes catastrophic failure under reverse surge |
Key Features

FAQ
What is the clamping voltage of the TMPG06-43AHE3_A/B at its rated peak pulse current?
The TMPG06-43AHE3_A/B has a maximum clamping voltage (VC) of 59.3 V at its peak pulse current (IPPM) of 6.7 A, measured under the standard 10/1000 µs waveform. This value is critical for verifying that protected circuits remain within their absolute maximum voltage ratings during surge events. The TMPG06-43AHE3_A/B achieves this clamping performance while maintaining low incremental resistance and thermal stability up to 185 °C junction temperature.
Is the TMPG06-43AHE3_A/B suitable for automotive applications?
Yes, the TMPG06-43AHE3_A/B is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and ADAS modules. Its 185 °C maximum junction temperature, RoHS-compliant HE3 plating (JESD 201 Class 2 whisker resistant), and validation across HTGB, HTRB, and temperature cycling tests confirm suitability for under-hood and chassis-mounted applications. The TMPG06-43AHE3_A/B meets ISO 7637-2 Pulse 1, 2a, and 5a immunity requirements when properly implemented.
What does the "HE3_A/B" suffix indicate in TMPG06-43AHE3_A/B?
The "HE3" suffix denotes RoHS-compliant matte tin plating that passes JESD 201 Class 2 whisker testing, ensuring long-term reliability in sealed or high-humidity environments. The "_A/B" indicates revision code - "A" and "B" are successive manufacturing revisions with identical electrical and mechanical specifications, both fully interchangeable in design. The TMPG06-43AHE3_A/B maintains full compliance with AEC-Q101 and UL 94 V-0 across both revisions.
How does the TMPG06-43AHE3_A/B compare to bidirectional TVS diodes?
The TMPG06-43AHE3_A/B is unidirectional only, meaning it protects against positive transients on a line referenced to ground - ideal for DC power rails like 36 V automotive supplies. Unlike bidirectional variants, it offers lower leakage (<1 µA at 36.8 V) and tighter VBR tolerance, but cannot suppress negative-going surges without external circuitry. For symmetric AC or data-line protection, a bidirectional part would be required; the TMPG06-43AHE3_A/B is optimized for asymmetric DC system protection.
What is the lead finish and solderability specification for TMPG06-43AHE3_A/B?
The TMPG06-43AHE3_A/B features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 for solderability, and withstands solder dip at 275 °C for up to 10 seconds per JESD 22-B106. The HE3 plating also satisfies JESD 201 Class 2 whisker resistance, eliminating risk of conductive filament growth in long-life applications. These attributes ensure consistent wetting and joint integrity during wave or hand-soldering processes used in TMPG06-43AHE3_A/B assembly.
