Product details
Overview
TMPG06-18HE3/73 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 V to 18.9 V breakdown voltage (VBR), 15.3 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 15.9 A peak pulse current (IPPM), and clamps to ≤25.5 V at rated surge - deployed on engine control units, sensor interfaces, and 12 V/24 V DC systems.
For engineers reviewing the TMPG06-18HE3/73 datasheet, TMPG06-18HE3/73 pinout, TMPG06-18HE3/73 application, or TMPG06-18HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, low 0.088 %/°C VBR temperature coefficient, unidirectional polarity with cathode band marking, and MPG06 package compatibility with high-reliability automotive PCB layouts.
Technical Context
The TMPG06-18HE3/73 operates as a silicon avalanche diode that enters controlled breakdown above VWM to shunt transient energy away from downstream ICs and MOSFETs. Its 10/1000 µs waveform response enables suppression of inductive switching spikes and ESD-induced transients without thermal runaway.
It delivers stable clamping performance across -65 °C to +185 °C operating range, with <1.0 µA reverse leakage at VWM, 3.5 V max forward voltage at 25 A, and JESD22-B106-compliant solderability (275 °C, 10 s). The device is qualified per AEC-Q101 stress test conditions for automotive under-hood use.

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). | Less suitable for sustained under-hood ambient >125 °C due to lower TJ rating (150 °C) and no AEC-Q101 qualification. | Select SMAJ18A only for cost-sensitive non-automotive applications where space is constrained and thermal cycling is mild. |
| 1.5KE18A | Higher PPPM (1500 W), larger DO-201 package, same VBR range, but not AEC-Q101 qualified and higher VC (28.5 V). | Designed for general-purpose industrial surge suppression; lacks automotive-grade process controls and whisker resistance. | Choose 1.5KE18A for high-energy single-event protection in non-automotive power supplies where board space allows larger package. |
Compared with SMAJ18A and 1.5KE18A, the TMPG06-18HE3/73 provides superior automotive reliability via AEC-Q101 qualification, tighter VBR tolerance (±5.5 %), lower clamping voltage (25.5 V vs. ≥28.5 V), and verified 185 °C operation - making it the preferred choice for safety-critical vehicle subsystems requiring long-term field stability.

FAQ
What is the maximum clamping voltage of the TMPG06-18HE3/73 at its rated peak pulse current?
The TMPG06-18HE3/73 has a maximum clamping voltage (VC) of 25.5 V at its rated peak pulse current of 15.9 A (10/1000 µs waveform). This value is guaranteed per the Vishay datasheet revision 17-Sep-2021 (Document Number: 88404) and ensures safe operation of downstream 30 V-rated components. The TMPG06-18HE3/73 achieves this clamping performance while maintaining low incremental resistance and stable thermal behavior up to 185 °C junction temperature.
Is the TMPG06-18HE3/73 qualified for automotive applications?
Yes, the TMPG06-18HE3/73 is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88404, Revision: 17-Sep-2021). It meets all stress tests required for automotive under-hood use, including temperature cycling, humidity bias, and mechanical shock. The HE3 suffix further certifies compliance with JESD201 Class 2 whisker resistance, making the TMPG06-18HE3/73 suitable for safety-critical vehicle subsystems such as engine control, ADAS sensors, and body electronics.
What does the "HE3/73" suffix indicate in TMPG06-18HE3/73?
The "HE3" suffix denotes RoHS-compliant construction, AEC-Q101 qualification, and JESD201 Class 2 whisker resistance; "73" is Vishay's internal packaging code indicating 5500-unit tape-and-reel delivery in 13" diameter reels with C-code packaging. This full designation confirms the TMPG06-18HE3/73 meets automotive reliability standards and supports automated SMT assembly. The TMPG06-18HE3/73 is not interchangeable with non-HE3 variants due to differing qualification and plating specifications.
How does the TMPG06-18HE3/73 compare to standard Zener diodes in transient suppression?
Unlike standard Zener diodes, the TMPG06-18HE3/73 is optimized for high-energy transient suppression with 400 W peak pulse power, low clamping voltage (25.5 V), and sub-nanosecond response time. It exhibits lower dynamic impedance and tighter VBR tolerance (±5.5 %) than general-purpose Zeners, enabling predictable protection margins. The TMPG06-18HE3/73 also features AEC-Q101 qualification and 185 °C operation - capabilities absent in standard Zener diodes used for voltage regulation rather than surge clamping.
Can the TMPG06-18HE3/73 be used in bidirectional configurations?
No, the TMPG06-18HE3/73 is specified for unidirectional polarity only, as stated in the Vishay datasheet. Its cathode is marked by a color band, and it conducts only in reverse breakdown - it does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a separate device such as the SMBJ18CA or a dual-diode array must be used. Using the TMPG06-18HE3/73 in reverse-biased signal paths without proper polarity alignment will result in failure to protect or unintended conduction. The TMPG06-18HE3/73 must be oriented with cathode toward the protected circuit's ground reference.
