Product details
Overview
TMPG06-12AHE3_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 11.4 V to 12.6 V breakdown voltage (VBR), 10.2 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 16.7 V clamping voltage at 24.0 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TMPG06-12AHE3_A/B datasheet, TMPG06-12AHE3_A/B pinout, TMPG06-12AHE3_A/B application, or TMPG06-12AHE3_A/B equivalent, key selection criteria include clamping performance under 10/1000 µs transients, junction temperature derating up to +185 °C, unidirectional polarity with cathode band marking, and RoHS-compliant, whisker-tested matte tin leads.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its specified breakdown range. Its low incremental resistance and fast response time ensure effective suppression of inductive switching spikes and ESD events without latch-up or thermal runaway.
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 infinite heatsink at TL = 75 °C, and maintains stable clamping behavior across -65 °C to +185 °C operating junction temperature - critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V - defines precise avalanche onset range for reliable triggering above normal operating voltage |
| VWM | 10.2 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 16.7 V - clamping voltage at 24.0 A peak pulse current; limits downstream voltage stress during transients |
| PPPM | 400 W - peak pulse power handling capability with 10/1000 µs waveform, enabling protection against ISO 7637-2 pulses |
| TJ max. | +185 °C - extended junction temperature rating supports operation in high-ambient automotive and industrial locations |
| IFSM | 40 A - surge current withstand for 8.3 ms half-sine wave, suitable for motor driver and relay coil snubbing |
| Polarity | Unidirectional - protects against negative-going transients only; cathode marked by color band |
Pinout & Package
Package: MPG06 - molded epoxy case with UL 94 V-0 flammability rating, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, HE3 suffix qualified per JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Avalanche conduction terminal | Marked with color band; connected to protected line (e.g., 12 V rail or sensor input) to clamp positive transients |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units, body electronics, and ADAS sensor interfaces |
| 400 W peak pulse power (10/1000 µs) | Meets ISO 7637-2 Pulse 1, 2a, 3a/b immunity requirements for 12 V systems |
| Low clamping ratio (VC/VBR ≈ 1.39) | Minimizes overvoltage margin between clamping and breakdown, improving system-level surge margin |
| +185 °C maximum junction temperature | Enables placement near heat sources (e.g., power MOSFETs, DC/DC converters) without derating penalties |
| RoHS-compliant, whisker-tested leads | Ensures long-term solder joint integrity in high-vibration automotive assemblies |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Value: 400 W PPPM absorbs energy from motor inductance; low VC/VBR ratio preserves MOSFET SOA during transient events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ12A | Lower PPPM (400 W same), but higher VC (20.9 V @ 19.2 A); SMA package (smaller footprint, lower thermal mass) | Less suitable for high-temperature under-hood use due to lower TJ max (150 °C vs. 185 °C) | Select SMAJ12A only if board space is constrained and ambient temperature remains below 105 °C. |
| 1.5KE12A | Higher PPPM (1500 W), TO-218 package; larger size, higher VC (20.1 V @ 74.6 A), not AEC-Q101 qualified | Applicable in non-automotive industrial power supplies where qualification and compactness are secondary | Choose 1.5KE12A for higher-energy surge environments where AEC-Q101 is not required and PCB area allows. |
Compared with SMAJ12A and 1.5KE12A, TMPG06-12AHE3_A/B delivers superior thermal robustness and automotive qualification in a compact MPG06 package, making it the preferred choice for space-constrained, high-reliability vehicle subsystems requiring validated AEC-Q101 compliance.

FAQ
What is the exact breakdown voltage range for TMPG06-12AHE3_A/B?
The TMPG06-12AHE3_A/B has a guaranteed breakdown voltage (VBR) range of 11.4 V to 12.6 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures predictable turn-on behavior in 12 V automotive and industrial systems where precise clamping thresholds are critical for protecting downstream ICs.
Is TMPG06-12AHE3_A/B suitable for bidirectional transient protection?
No - TMPG06-12AHE3_A/B is unidirectional only, with polarity indicated by a cathode color band. It protects against positive transients on the cathode side relative to anode (ground). For bidirectional protection, two devices in series opposition or a dedicated bidirectional TVS such as SMBJ12CA would be required instead of TMPG06-12AHE3_A/B.
Does TMPG06-12AHE3_A/B meet automotive qualification standards?
Yes - TMPG06-12AHE3_A/B is explicitly AEC-Q101 qualified, as confirmed in Vishay document 88404. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of TMPG06-12AHE3_A/B under surge conditions?
The maximum clamping voltage (VC) of TMPG06-12AHE3_A/B is 16.7 V at 24.0 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can TMPG06-12AHE3_A/B be used in high-temperature environments like engine compartments?
Yes - TMPG06-12AHE3_A/B supports an operating junction temperature range of -65 °C to +185 °C, significantly exceeding typical automotive under-hood requirements. Its thermal design, combined with AEC-Q101 qualification, makes TMPG06-12AHE3_A/B appropriate for direct placement on engine control modules and other high-ambient-temperature locations.
