Product details
Overview
TMPG06-20A-E3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in MPG06 package, designed for automotive-grade overvoltage protection. It features 19.0–21.0 V breakdown voltage (VBR), 1.0 W steady-state power dissipation (PD), 400 W peak pulse power (PPPM) at 10/1000 µs, 14.4 A peak pulse current (IPPM), and clamps to ≤27.7 V at rated surge. It protects MOSFETs and sensor signal lines in automotive ECUs against inductive switching transients.
For engineers reviewing the TMPG06-20A-E3/73 datasheet, TMPG06-20A-E3/73 pinout, TMPG06-20A-E3/73 application, or TMPG06-20A-E3/73 equivalent, this page delivers verified electrical specs, thermal limits, clamping behavior, RoHS-compliant construction, and AEC-Q101-relevant reliability data - all specific to the E3/73 commercial-grade variant with matte tin-plated leads and UL 94V-0 epoxy case.
Technical Context
This TVS diode uses patented PAR® construction for low incremental surge resistance and fast response (<1 ns), enabling effective suppression of fast-rising transients from load dump or relay bounce. Its unidirectional polarity and cathode band marking align with standard PCB layout conventions for reverse-biased protection across DC rails.
Rated for TJ = –65 °C to +185 °C operation, it maintains stable VBR with 0.090 %/°C temperature coefficient and exhibits <1.0 µA reverse leakage at 17.0 V (VWM) - critical for low-power sensor interfaces where standby current must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.0 V / 21.0 V at 1.0 mA test current - defines reliable conduction onset under transient stress |
| VC @ IPPM | ≤27.7 V at 14.4 A - maximum clamped voltage seen by protected IC during 10/1000 µs surge |
| PPPM | 400 W - peak surge energy handling per single 10/1000 µs pulse, duty cycle ≤0.01 % |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without failure, critical for motor driver protection |
| TJ max. | +185 °C - enables placement near high-temperature components in engine control modules |
| VWM | 17.0 V - maximum continuous reverse working voltage before significant leakage begins |
| Leakage @ VWM | ≤1.0 µA at 25 °C - ensures minimal loading on low-current sensor supply rails |
Pinout & Package
Package: MPG06 - molded epoxy case, UL 94V-0 rated, matte tin-plated leads solderable per J-STD-002B/JESD22-B102D. Cathode denoted by color band.

Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ20A | Same VBR range (19.0–21.0 V), but lower PPPM = 400 W only at 10/1000 µs; SMA package vs. MPG06 - smaller footprint but lower thermal mass | Less suitable for high-temperature under-hood locations due to lower TJ max. (150 °C vs. 185 °C) | Select SMAJ20A only if board space is constrained and ambient temperature remains below 105 °C. |
| SMCJ20A | Higher PPPM = 1500 W, same VBR, but larger SMC package; TJ max. = 175 °C | Better for high-energy surge environments (e.g., heavy-duty vehicle battery leads), but requires more PCB area | Choose SMCJ20A when system-level testing reveals >400 W surge exposure or when derating margin is insufficient with TMPG06-20A-E3/73. |
Compared with SMAJ20A and SMCJ20A, the TMPG06-20A-E3/73 offers optimal balance of high-temperature capability (+185 °C), compact MPG06 form factor, and precise 17.0 V working voltage - making it preferred for space-constrained automotive modules requiring extended thermal robustness without sacrificing surge rating.

FAQ
What is the maximum clamping voltage of the TMPG06-20A-E3/73 at its rated peak pulse current?
The TMPG06-20A-E3/73 clamps to a maximum of 27.7 V when subjected to its rated peak pulse current of 14.4 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Electrical Characteristics table of Vishay Document Number 88404. The clamping performance ensures protected circuits remain within safe operating voltage limits during surge events. This specification directly supports design margin calculations for 24 V automotive systems using the TMPG06-20A-E3/73.
Is the TMPG06-20A-E3/73 suitable for automotive applications requiring AEC-Q101 qualification?
The TMPG06-20A-E3/73 is the commercial-grade variant (E3 suffix); full AEC-Q101 qualification applies to the HE3 suffix version (e.g., TMPG06-20A-HE3). However, the TMPG06-20A-E3/73 shares identical die, PAR® construction, and thermal ratings (TJ max. = +185 °C), making it widely used in automotive pre-production and non-safety-critical modules. For production deployment requiring formal AEC-Q101 certification, the HE3 variant must be specified. The TMPG06-20A-E3/73 remains fully compatible in layout and electrical behavior.
What does the "73" in TMPG06-20A-E3/73 indicate?
"73" is Vishay's internal packaging code indicating tape-and-reel delivery in 7-inch diameter reels. It corresponds to a base quantity of 5500 units per reel, consistent with the ordering information in Document Number 88404. This differs from the "54" code (13-inch reel) used for other variants. The TMPG06-20A-E3/73 is supplied in this format to support automated SMT assembly lines with standard feeder compatibility. All electrical and thermal specifications of the TMPG06-20A-E3/73 remain unchanged regardless of reel size.
How does the temperature coefficient of VBR affect the TMPG06-20A-E3/73 in high-temperature environments?
The TMPG06-20A-E3/73 has a VBR temperature coefficient of +0.090 %/°C, meaning its breakdown voltage increases by approximately 18 mV per °C rise above 25 °C. At +125 °C ambient, VBR shifts to ~21.8 V - still within safe margin for a 24 V system. This predictable positive drift prevents premature conduction while maintaining effective clamping. Designers using the TMPG06-20A-E3/73 in under-hood applications rely on this stable coefficient to ensure consistent protection across the full –40 °C to +125 °C operating range.
Can the TMPG06-20A-E3/73 replace a bidirectional TVS in AC-coupled signal line protection?
No - the TMPG06-20A-E3/73 is unidirectional only, with polarity marked by a cathode band. It conducts only during positive transients relative to its cathode. For AC-coupled or bipolar signal lines (e.g., USB, CAN, RS-485 differential pairs), a bidirectional TVS such as SMBJ20CA is required. Using the unidirectional TMPG06-20A-E3/73 in such roles risks forward conduction during negative excursions, potentially damaging the device or distorting signals. Always verify polarity alignment before substituting the TMPG06-20A-E3/73 into existing designs.
