Product details
Overview
TMPG06-18AHE3/54 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 17.1–18.9 V breakdown voltage (VBR), 15.3 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 25.5 V clamping voltage at 15.9 A, and AEC-Q101 qualification - deployed to safeguard MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the TMPG06-18AHE3/54 datasheet, TMPG06-18AHE3/54 pinout, TMPG06-18AHE3/54 application, or TMPG06-18AHE3/54 equivalent, key selection criteria include verified unidirectional clamping performance, 185 °C maximum junction temperature, MPG06 package compatibility with high-reliability automotive PCB layouts, and compliance with JESD201 Class 2 whisker resistance and UL 94 V-0 molding.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (17.1–18.9 V), it avalanches rapidly (<1 ns response) to divert surge current away from downstream ICs. Its low incremental resistance ensures stable clamping at 25.5 V under 15.9 A IPPM, minimizing stress on protected circuits during 10/1000 µs transients.
The device is rated for 1.0 W steady-state power dissipation at TL = 75 °C, supports 40 A non-repetitive forward surge (8.3 ms half-sine), and maintains reliability across -65 °C to +185 °C junction temperature range - validated per AEC-Q101 for under-hood automotive environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ18A | Same VWM (15.3 V), but lower PPPM (400 W same), higher VC (29.2 V), SMA package (smaller footprint, lower thermal mass) | Limited to lower-energy transients due to reduced thermal derating margin; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is not required |
| SMCJ18A | Same VWM and VC, but higher PPPM (1500 W), larger SMC package, identical AEC-Q101 qualification | Overqualified for 400 W use cases; requires more PCB area and higher mounting force | Select when future-proofing against higher-energy threats or when shared BOM with higher-power variants is preferred |
Compared with SMAJ18A and SMCJ18A, the TMPG06-18AHE3/54 delivers optimal balance of AEC-Q101 compliance, 400 W surge capacity, and MPG06 package robustness - enabling direct integration into automotive power modules without thermal or layout compromise.

FAQ
What is the clamping voltage of TMPG06-18AHE3/54 at its rated peak pulse current?
The TMPG06-18AHE3/54 has a maximum clamping voltage (VC) of 25.5 V at its rated peak pulse current (IPPM) of 15.9 A, measured using the standardized 10/1000 µs waveform. This value ensures predictable overvoltage limiting during transient events and is confirmed in the Electrical Characteristics table of Vishay document 88404. The TMPG06-18AHE3/54 maintains this clamping performance across its specified operating temperature range.
Is TMPG06-18AHE3/54 qualified for automotive applications?
Yes, TMPG06-18AHE3/54 is AEC-Q101 qualified, meaning it has passed rigorous stress tests for automotive-grade reliability including temperature cycling, high-temperature operating life, and mechanical shock. The HE3 suffix further confirms compliance with JESD201 Class 2 whisker resistance. This qualification makes TMPG06-18AHE3/54 suitable for under-hood and body-control module applications where long-term stability is critical.
What does the "HE3/54" suffix indicate in TMPG06-18AHE3/54?
The "HE3" suffix denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads meeting J-STD-002 solderability and JESD201 Class 2 whisker resistance. The "/54" indicates tape-and-reel packaging per Vishay's preferred delivery mode: 5500 units per 13-inch reel. Both identifiers are defined in the Ordering Information section of document 88404 and apply specifically to the TMPG06-18AHE3/54 variant.
How does TMPG06-18AHE3/54 compare to bidirectional TVS diodes in circuit design?
TMPG06-18AHE3/54 is unidirectional and protects only against positive transients relative to ground - ideal for DC power rails where polarity is fixed. Unlike bidirectional types, it avoids leakage path complications in polarized circuits and offers lower capacitance. For AC or differential signal lines, a bidirectional device would be required; the TMPG06-18AHE3/54 must be oriented with cathode toward the higher-potential side to function correctly.
What is the maximum operating temperature for TMPG06-18AHE3/54?
The TMPG06-18AHE3/54 has a maximum junction temperature (TJ) of +185 °C and an operating junction/storage temperature range of –65 °C to +185 °C. This extended range supports deployment in high-ambient environments such as engine control units and industrial motor drives. Derating curves in Figure 2 of document 88404 define allowable power reduction above 25 °C ambient, ensuring safe operation of TMPG06-18AHE3/54 across its full thermal envelope.
