Product details
Overview
TMPG06-12AHE3_A/D 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 16.7 V under 24.0 A peak pulse current, and operates with a 11.4–12.6 V breakdown voltage at 1 mA test current. Its AEC-Q101 qualification and 185 °C max junction temperature support use in engine control units and battery management systems.
For engineers reviewing the TMPG06-12AHE3_A/D datasheet, TMPG06-12AHE3_A/D pinout, TMPG06-12AHE3_A/D application, or TMPG06-12AHE3_A/D equivalent, key selection criteria include clamping voltage (VC = 16.7 V), stand-off voltage (VWM = 10.2 V), low incremental resistance, fast response time, and RoHS-compliant, whisker-tested matte tin-plated leads in MPG06 package.
Technical Context
This TVS diode uses a passivated silicon junction in a molded epoxy MPG06 case rated UL 94 V-0, optimized for high-reliability transient suppression in harsh environments. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked until clamping threshold is exceeded.
The device exhibits 0.078 %/°C temperature coefficient of VBR and maintains stable clamping performance up to 150 °C junction temperature, with <1 μA reverse leakage at VWM and 5 μA at TJ = 150 °C - critical for low-power sensor interfaces and always-on automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 11.4–12.6 V at 1 mA - defines precise clamping onset threshold for 12 V nominal systems |
| Stand-off Voltage VWM | 10.2 V - ensures no conduction during normal 12 V rail operation, minimizing standby leakage |
| Clamping Voltage VC | 16.7 V at IPPM = 24.0 A - limits transient voltage seen by downstream ICs to safe levels |
| Peak Pulse Power PPPM | 400 W (10/1000 µs) - withstands ISO 7637-2 Pulse 1/2a/5a transients in automotive ECUs |
| Max Junction Temperature | 185 °C - supports placement near hot components like power MOSFETs or DC-DC converters |
| AEC-Q101 Qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
| Package | MPG06 - axial-leaded, 2.54 mm lead spacing, compatible with through-hole reflow and wave soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ12A | Same VWM (10.2 V) and VC (16.7 V), but SMB package (surface-mount); lower PPPM (600 W) not applicable - actual PPPM = 400 W matches | Requires PCB redesign for SMD layout; better suited for space-constrained boards vs. through-hole mounting | Select SMBJ12A when board real estate is limited and reflow assembly is used; verify thermal pad design for 1.0 W PD |
| P6SMB12A | Identical electrical specs (VBR, VWM, VC, PPPM), same AEC-Q101 qualification, but legacy SMB package with different moisture sensitivity level (MSL 1) | No change in protection performance; differs only in packaging logistics and handling requirements | Choose P6SMB12A if existing SMT process already qualifies MSL 1 parts; otherwise TMPG06-12AHE3_A/D offers axial-leaded ease-of-use and wave-solder compatibility |
Compared with SMBJ12A and P6SMB12A, TMPG06-12AHE3_A/D provides identical clamping behavior and automotive qualification but delivers mechanical robustness and thermal resilience via its axial-leaded MPG06 package - ideal for high-vibration environments and mixed-technology assemblies requiring both through-hole and SMT components.

FAQ
What is the maximum clamping voltage of the TMPG06-12AHE3_A/D under specified test conditions?
The TMPG06-12AHE3_A/D has a maximum clamping voltage (VC) of 16.7 V when subjected to a 24.0 A peak pulse current with a 10/1000 µs waveform. This value is measured per JEDEC standards and ensures downstream components remain within safe operating voltage limits during transient events. The clamping performance is guaranteed across the full operating temperature range up to 150 °C junction temperature.
Is the TMPG06-12AHE3_A/D suitable for automotive applications?
Yes, the TMPG06-12AHE3_A/D is AEC-Q101 qualified and explicitly designed for automotive use. It meets rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD immunity. Its 185 °C maximum junction temperature, low leakage (<1 μA at VWM), and UL 94 V-0 package make it appropriate for engine control units, body control modules, and battery management systems.
What does the "HE3_A/D" suffix indicate in TMPG06-12AHE3_A/D?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads that pass JESD 201 Class 2 whisker testing, while "_A/D" indicates the revision code per Vishay's ordering nomenclature - confirming compliance with the 17-Sep-2021 revision of document 88404. This suffix ensures traceability to the qualified manufacturing lot and material specification.
How does the TMPG06-12AHE3_A/D compare to bidirectional TVS diodes in circuit design?
The TMPG06-12AHE3_A/D is unidirectional only, meaning it blocks reverse voltage up to –10.2 V and clamps positive transients above +12.6 V. Unlike bidirectional variants, it cannot protect AC or bipolar signal lines. Its advantage lies in lower leakage and tighter VBR tolerance for DC-biased rails - making it optimal for 12 V power inputs, LIN bus, and sensor supply lines where polarity is fixed.
What is the thermal derating behavior of TMPG06-12AHE3_A/D above 25 °C ambient?
The TMPG06-12AHE3_A/D follows standard derating per Figure 2 in its datasheet: peak pulse power decreases linearly above TA = 25 °C, reaching ~50 % of 400 W at 125 °C ambient. Continuous power dissipation (PD = 1.0 W) is rated at TL = 75 °C lead temperature; for higher ambient operation, thermal relief (e.g., wider copper pours) is recommended to maintain junction temperature ≤185 °C.
