Product details
Overview
TMPG06-20AHE3_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 delivers 400 W peak pulse power (10/1000 µs), clamps at 27.7 V under 14.4 A peak pulse current, and operates across -65 °C to +185 °C junction temperature - enabling use in engine control units and battery management systems.
For engineers reviewing the TMPG06-20AHE3_A/B datasheet, TMPG06-20AHE3_A/B pinout, TMPG06-20AHE3_A/B application, or TMPG06-20AHE3_A/B equivalent, key selection criteria include its AEC-Q101 qualification, 17.0 V stand-off voltage, low 0.090 %/°C VBR temperature coefficient, and MPG06 package compatibility with high-reliability PCB assembly processes.
Technical Context
This TVS diode employs a passivated silicon junction in a molded epoxy MPG06 case rated UL 94 V-0, optimized for fast response (<1 ns) to ESD and inductive switching transients. Its low incremental resistance and 3.5 V max forward voltage at 25 A support effective clamping without excessive power dissipation during surge events.
Designed for repetitive 0.01 % duty cycle operation, it maintains stable performance under thermal stress: derated linearly above 25 °C ambient per Fig. 2, with 1.0 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature and full 40 A IFSM surge rating per JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 400 W - sustains automotive load-dump and ISO 7637-2 pulse 5a transients without failure |
| Stand-off Voltage VWM | 17.0 V - sets maximum continuous operating voltage before leakage exceeds 1 µA |
| Breakdown Voltage VBR | 19.0–21.0 V at 1 mA - defines onset of avalanche conduction for precise clamping threshold |
| Clamping Voltage VC | 27.7 V at 14.4 A IPPM - limits protected circuit voltage during worst-case surge |
| Junction Temperature Range | -65 °C to +185 °C - supports under-hood automotive placement and industrial high-temp environments |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
| Package | MPG06 - axial-leaded, RoHS-compliant, matte tin-plated leads, UL 94 V-0 molding compound |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential side of protected line; enables bidirectional surge suppression only when paired with complementary device |
| Cathode | Current exit terminal during forward conduction; marked by color band | Connected to higher-potential rail (e.g., VBAT) - defines unidirectional clamping direction from cathode to anode |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | DO-214AC package; 20 V VWM, 32.4 V VC at 12.3 A; 400 W rating; same AEC-Q101 qualification | Surface-mount footprint - requires PCB redesign; lower thermal mass limits sustained surge handling vs. axial MPG06 | Select when board space is constrained and reflow assembly is preferred over through-hole. |
| P6SMB20A | DO-214AA package; 20 V VWM, 32.4 V VC at 12.3 A; 600 W rating; AEC-Q101 qualified | Higher peak power but larger package; different thermal derating curve - may require revised layout for heat dissipation | Choose for higher surge margin where mechanical clearance allows larger SMC outline. |
Compared with SMAJ20A and P6SMB20A, TMPG06-20AHE3_A/B offers superior thermal robustness in axial through-hole mounting, tighter VBR tolerance (±5 %), and proven reliability in high-vibration automotive harness environments - making it optimal for legacy-compatible designs requiring field-proven mechanical stability.

FAQ
What is the maximum clamping voltage of TMPG06-20AHE3_A/B under rated surge conditions?
The TMPG06-20AHE3_A/B clamps to a maximum of 27.7 V when subjected to its rated 14.4 A peak pulse current (IPPM) using the 10/1000 µs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 88404) and reflects worst-case voltage seen by downstream circuitry during transient events - critical for ensuring protected ICs remain within absolute maximum ratings.
Is TMPG06-20AHE3_A/B suitable for automotive applications requiring AEC-Q101 certification?
Yes, TMPG06-20AHE3_A/B is explicitly AEC-Q101 qualified per the Vishay datasheet revision dated 17-Sep-2021. It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and unbiased highly accelerated stress test (uHAST), confirming suitability for under-hood and powertrain electronics where reliability is mission-critical.
How does the MPG06 package of TMPG06-20AHE3_A/B differ from DO-214 surface-mount alternatives?
The MPG06 package of TMPG06-20AHE3_A/B is an axial-leaded, through-hole molded epoxy case with ≥25.4 mm minimum length and tin-plated leads - offering higher thermal mass and mechanical robustness in vibration-prone environments. Unlike DO-214 variants, it supports manual or wave-solder assembly and provides superior heat dissipation in high-duty-cycle surge scenarios without requiring thermal pads or vias.
What is the reverse leakage current specification for TMPG06-20AHE3_A/B at its stand-off voltage?
At 25 °C and its 17.0 V stand-off voltage (VWM), TMPG06-20AHE3_A/B exhibits a maximum reverse leakage current (ID) of 1.0 µA. At elevated temperature (150 °C), leakage remains ≤5.0 µA - ensuring minimal power loss and no interference with low-current sensor or monitoring circuits powered from the same rail.
Can TMPG06-20AHE3_A/B be used in bidirectional transient protection configurations?
No - TMPG06-20AHE3_A/B is unidirectional only, as confirmed in the Vishay datasheet features section. For bidirectional protection, two devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated bidirectional TVS such as SMBJ20CA should be selected. Using a single TMPG06-20AHE3_A/B in reverse-biased configuration risks catastrophic failure due to lack of reverse breakdown specification.
