Product details
Overview
TMPG06-12HE3/54 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 12 V breakdown voltage (VBR = 11.4–12.6 V at 1 mA), 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 TMPG06-12HE3/54 datasheet, TMPG06-12HE3/54 pinout, TMPG06-12HE3/54 application, or TMPG06-12HE3/54 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 compatibility with lead-free reflow and solder dip (275 °C, 10 s).
Technical Context
The TMPG06-12HE3/54 operates as a silicon avalanche diode that enters controlled breakdown above its specified VBR, limiting transient voltages to ≤16.7 V at 24.0 A. Its low incremental resistance and fast response time ensure effective suppression of inductive switching spikes and ESD events without affecting normal circuit operation below VWM = 10.2 V.
Designed for high-reliability environments, it supports continuous operation from –65 °C to +185 °C junction temperature, with thermal derating per Figure 2 and compliance to JESD 201 Class 2 whisker testing. The device is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and exhibits only 1.0 µA reverse leakage at VWM and 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.4 V / 12.6 V at 1.0 mA - defines precise avalanche initiation threshold for predictable clamping onset |
| VWM | 10.2 V - maximum continuous working voltage before leakage exceeds 1.0 µA; sets safe operating margin below VBR |
| VC @ IPPM | 16.7 V at 24.0 A (10/1000 µs) - peak clamped voltage seen by protected IC/MOSFET during worst-case surge |
| PPPM | 400 W - energy-handling capacity for standardized lightning/surge transients per IEC 61000-4-5 |
| TJ max. | +185 °C - enables use in under-hood automotive modules and high-ambient industrial controls without thermal shutdown |
| Polarity | Unidirectional - protects against positive-going transients only; cathode marked by color band |
| Package | MPG06 - surface-mount DO-219AB outline (2.54 mm lead spacing, 3.18 mm body height), UL 94 V-0 compliant |
Pinout & Package
MPG06 package: molded epoxy case with matte tin-plated leads; cathode indicated by axial color band; lead spacing 0.100" (2.54 mm); RoHS-compliant and AEC-Q101 qualified.

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 | Same VWM (10.2 V) and VC (19.9 V @ 21.5 A), but lower PPPM (400 W same), larger SMA package (DO-214AC), higher VC/VBR ratio (1.66 vs. 1.39) | Less space-constrained PCBs; not AEC-Q101 qualified; suited for commercial-grade consumer electronics | Select when footprint flexibility exists and automotive qualification is unnecessary |
| SMCJ12A | Higher PPPM (1500 W), same VWM/VBR, larger SMC package (DO-214AB), VC = 19.9 V @ 75.0 A, no AEC-Q101 rating | Used where higher surge energy (e.g., IEC 61000-4-5 Level 4) must be absorbed; incompatible with MPG06 land pattern | Choose only if system-level surge test requirements exceed 400 W and board layout allows SMC footprint |
Compared with SMAJ12A and SMCJ12A, the TMPG06-12HE3/54 delivers superior clamping efficiency (lower VC/VBR) and automotive-grade reliability in the smallest qualified surface-mount TVS package, making it optimal for space- and qualification-critical 12 V rail protection.

FAQ
What is the maximum clamping voltage of the TMPG06-12HE3/54 under standard surge conditions?
The TMPG06-12HE3/54 clamps to a maximum of 16.7 V when subjected to a 10/1000 µs waveform with a peak pulse current of 24.0 A. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 88404) and represents the upper bound of voltage seen by protected circuitry during worst-case transient events. The TMPG06-12HE3/54 maintains this clamping performance across its full operating temperature range.
Is the TMPG06-12HE3/54 suitable for automotive applications?
Yes, the TMPG06-12HE3/54 is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive modules including body control units, lighting drivers, and battery management subsystems. Its MPG06 package meets JESD 201 Class 2 whisker resistance, and the TMPG06-12HE3/54 is explicitly listed in Vishay's AEC-Q101 stress-tested product table.
What does the "HE3/54" suffix indicate in TMPG06-12HE3/54?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. The "/54" indicates tape-and-reel packaging per EIA-481-D standard, with 5500 units per 13-inch reel. This full designation confirms the TMPG06-12HE3/54 is the production-ready, automotive-qualified variant shipped in industry-standard logistics format.
How does the TMPG06-12HE3/54 compare to bidirectional TVS diodes?
The TMPG06-12HE3/54 is unidirectional and protects only against positive transients relative to ground; it must be installed with cathode toward the protected line. Bidirectional variants (e.g., TMPG06-12CA) protect both polarities but exhibit higher leakage and reduced VBR precision. For 12 V DC systems where only positive surges occur-such as automotive battery rails-the TMPG06-12HE3/54 offers tighter clamping and lower leakage than equivalent bidirectional parts.
Can the TMPG06-12HE3/54 be used in parallel for higher surge current handling?
No-parallel connection of TMPG06-12HE3/54 devices is not recommended due to mismatch in VBR tolerance (±5 %) and dynamic impedance, which causes uneven current sharing and potential thermal runaway. For higher surge ratings, select a single higher-power device such as the SMCJ12A, or implement staged protection with upstream current-limiting elements before the TMPG06-12HE3/54.
