Product details
Overview
TMPG06-15AHE3_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 21.2 V under 18.9 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 TMPG06-15AHE3_A/B datasheet, TMPG06-15AHE3_A/B pinout, TMPG06-15AHE3_A/B application, or TMPG06-15AHE3_A/B equivalent, key selection criteria include its AEC-Q101 qualification, 12.8 V stand-off voltage, low 0.084 %/°C VBR temperature coefficient, and MPG06 package compatibility with high-reliability soldering processes.
Technical Context
This TVS diode employs a passivated silicon junction in a molded epoxy MPG06 case, optimized for fast response (<1 ns) and low incremental resistance to limit transient-induced voltage overshoot during inductive switching events. Its unidirectional polarity and cathode band marking ensure correct orientation in DC-biased protection circuits.
The device is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine), supports 1.0 W steady-state power dissipation on infinite heatsink at 75 °C, and maintains stable clamping performance up to 185 °C maximum junction temperature - meeting stringent thermal requirements in under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 400 W - sustains high-energy transients without failure in automotive load-dump or ISO 7637-2 pulse 5a scenarios |
| Stand-off Voltage (VWM) | 12.8 V - reliably blocks normal 12 V system operation while triggering above this threshold |
| Breakdown Voltage (VBR) | 14.3–15.8 V at 1 mA - defines precise conduction onset for predictable clamping behavior |
| Clamping Voltage (VC) | 21.2 V at 18.9 A - limits downstream IC voltage stress during worst-case surge conditions |
| Junction Temperature Range | -65 °C to +185 °C - enables deployment in extreme ambient environments including powertrain and battery modules |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements including HTGB, HTRB, and TCT |
| Package | MPG06 - axial-leaded, UL 94 V-0 molded epoxy case with matte tin-plated leads compliant to J-STD-002 |
Pinout & Package
MPG06 is an axial-leaded package with cathode identified by a color band. Leads are matte tin-plated and rated for solder dip at 275 °C for 10 s (JESD 22-B106). The device has two terminals: anode and cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to protected circuit ground or low-side return path | Completes conduction path during reverse-transient clamping when cathode is held at higher potential |
| Cathode | Negative terminal; marked with color band; connected to protected line or supply rail | Acts as the input node for transient energy absorption - clamps voltage relative to anode reference |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | 185 °C max junction temperature and 0.084 %/°C VBR coefficient ensure consistent clamping across automotive thermal cycles |
| AEC-Q101 qualification | Validated for automotive electronics per JEDEC stress tests - eliminates need for additional qualification effort in Tier-1 designs |
| Low incremental resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 16750-2 pulse 4a), improving protection margin for 12 V logic interfaces |
| 400 W peak pulse rating | Handles high-energy surges from inductive loads (e.g., fuel injectors, solenoids) without degradation over lifetime |
| RoHS-compliant HE3 suffix | Meets JESD 201 Class 2 whisker resistance and RoHS Directive 2011/65/EU - suitable for lead-free assembly and long-term reliability |
Applications
| Engine Control Unit (ECU) Power Input Protection | Automotive Battery Management System (BMS) Signal Line Protection |
|---|---|
Use Scenario: Protects 12 V supply input of ECU against load dump and alternator transients per ISO 7637-2.

IC Role / Device Role / Timing Role: Primary-stage TVS in coordination with MOVs to share energy and extend system surge life. Use Value: 400 W peak pulse power and low clamping ratio (VC/VBR ≈ 1.37) reduce stress on downstream filtering components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | Same 15 V nominal breakdown but SMA package (surface-mount); lower 400 W rating applies only at 25 °C (derates faster above TA) | Requires PCB rework for SMT layout; unsuitable for through-hole or high-vibration mechanical mounting | Select when board space is constrained and automated assembly is prioritized over mechanical robustness |
| P6SMB15A | Higher 600 W peak pulse power but larger SMB package; VC = 24.4 V at 24.7 A - less tight clamping than TMPG06-15AHE3_A/B | Better for higher-energy threats but increases risk of overvoltage stress on 12 V logic; not AEC-Q101 qualified | Choose only for non-automotive industrial applications where clamping voltage margin is secondary to energy handling |
Compared with SMAJ15A and P6SMB15A, TMPG06-15AHE3_A/B provides superior thermal endurance (185 °C TJ max), AEC-Q101 validation, and axial-leaded mechanical stability - making it the preferred choice for automotive power rail protection where reliability and mounting integrity are critical.

FAQ
What is the clamping voltage of the TMPG06-15AHE3_A/B at its rated peak pulse current?
The TMPG06-15AHE3_A/B has a maximum clamping voltage (VC) of 21.2 V at 18.9 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per Figure 3 in the Vishay datasheet 88404 and ensures predictable overvoltage limiting for downstream 12 V electronics. The TMPG06-15AHE3_A/B maintains this clamping performance across its full operating temperature range.
Is the TMPG06-15AHE3_A/B qualified for automotive applications?
Yes, the TMPG06-15AHE3_A/B is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 17-Sep-2021 (Document Number: 88404). It has passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), confirming suitability for under-hood and powertrain applications. The TMPG06-15AHE3_A/B also meets JESD 201 Class 2 whisker resistance and RoHS requirements.
What does the "HE3_A/B" suffix indicate in TMPG06-15AHE3_A/B?
The "HE3" suffix denotes Vishay's RoHS-compliant, matte tin-plated leads that meet JESD 201 Class 2 whisker resistance requirements. The "_A/B" indicates revision code - "A" and "B" refer to different manufacturing lots or process revisions, both fully compliant with the same electrical and mechanical specifications in datasheet 88404. The TMPG06-15AHE3_A/B is functionally identical across these revisions.
Can the TMPG06-15AHE3_A/B be used in bidirectional protection circuits?
No, the TMPG06-15AHE3_A/B is unidirectional only, as confirmed in the FEATURES section of the Vishay datasheet. It conducts in reverse bias to clamp positive transients relative to its cathode and cannot suppress negative-going surges on the anode side. For bidirectional protection, a separate device such as the SMBJ15CA or a back-to-back configuration would be required - the TMPG06-15AHE3_A/B is not rated or characterized for symmetrical clamping.
What is the maximum operating temperature for the TMPG06-15AHE3_A/B?
The TMPG06-15AHE3_A/B has a maximum junction temperature (TJ) of +185 °C and a storage temperature range of -65 °C to +185 °C. Its thermal performance is validated up to this limit, and derating curves (Figure 2 in datasheet 88404) define allowable pulse power reduction above 25 °C ambient. This makes the TMPG06-15AHE3_A/B suitable for high-temperature zones like engine compartments and power inverters.
