Product details
Overview
TMPG06-20-1HE3_A/B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. It features a 19.0–21.0 V breakdown voltage (VBR), 17.0 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 14.4 A peak pulse current (IPPM), and clamps to ≤27.7 V at rated surge - deployed on 12 V battery lines, sensor supply inputs, and MOSFET gate drivers.
For engineers reviewing the TMPG06-20-1HE3_A/B datasheet, TMPG06-20-1HE3_A/B pinout, TMPG06-20-1HE3_A/B application, or TMPG06-20-1HE3_A/B equivalent, key selection criteria include AEC-Q101 qualification, 185 °C max junction temperature, unidirectional polarity with cathode band marking, low incremental resistance, and high-temperature stability under repetitive transients.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, triggering when reverse voltage exceeds its specified VBR range (19.0–21.0 V). Its low dynamic impedance ensures rapid voltage suppression during ESD or load-dump events, with response time under 1 ns and clamping ratio (VC/VBR) of ~1.39.
Rated for 40 A non-repetitive forward surge (8.3 ms half-sine), it sustains 1.0 W steady-state power dissipation at TL = 75 °C and exhibits <1.0 µA reverse leakage at VWM (17.0 V) up to 150 °C - confirming suitability for high-reliability automotive environments per AEC-Q101 stress test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 19.0 V / 21.0 V - defines precise clamping initiation threshold; ensures reliable turn-on before downstream IC damage. |
| VWM | 17.0 V - maximum continuous reverse operating voltage; allows safe operation across 12 V nominal systems with ripple margin. |
| IPPM (10/1000 µs) | 14.4 A - peak surge current handling capacity; supports ISO 7637-2 Pulse 1 & 2a load-dump immunity. |
| VC @ IPPM | ≤27.7 V - clamped voltage during full-rated surge; guarantees protected node stays below 30 V absolute maximum rating. |
| PPPM | 400 W - peak pulse power rating; enables single-device protection against high-energy transients without derating. |
| TJ max | +185 °C - extended junction temperature rating; supports under-hood placement and high-ambient industrial use. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per AEC standard. |

Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables targeted protection of DC power rails without interfering with forward-biased signal paths. |
| 400 W peak pulse power (10/1000 µs) | Provides single-device resilience against ISO 16750-2 load-dump and ISO 7637-2 Pulse 5a surges in automotive ECUs. |
| AEC-Q101 qualification | Confirms compliance with automotive stress tests including high-temperature reverse bias and accelerated life testing. |
| 185 °C max junction temperature | Supports direct mounting near heat sources (e.g., power converters) without thermal derating penalties. |
| Low incremental resistance | Minimizes VC – VBR spread, ensuring tighter clamping control and reduced energy dissipation in protected circuits. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Module |

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 VWM (17.1 V), lower PPPM (400 W same), but SMA package (smaller footprint, lower IPPM = 13.9 A) | Preferred for space-constrained PCBs where thermal mass is sufficient; not AEC-Q101 qualified | Select when automotive qualification is not required and board area is critical. |
| TPSMF20A | Same VWM (17.1 V), identical PPPM (400 W), SOD-123FL package, AEC-Q101 qualified, but lower IFSM (30 A vs. 40 A) | Better suited for high-density layouts with automated assembly; limited surge endurance in high-current inductive switching | Choose for reflow-compatible surface-mount designs needing AEC-Q101 compliance and smaller form factor. |
Compared with SMAJ20A and TPSMF20A, TMPG06-20-1HE3_A/B offers superior surge current handling (40 A IFSM), axial-leaded mechanical robustness for through-hole reliability, and proven thermal performance up to +185 °C - making it optimal for under-hood and high-vibration industrial deployments.

FAQ
What is the exact breakdown voltage range for TMPG06-20-1HE3_A/B?
The TMPG06-20-1HE3_A/B has a guaranteed breakdown voltage (VBR) range of 19.0 V to 21.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35 standards. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 12 V system designs.
Is TMPG06-20-1HE3_A/B qualified for automotive applications?
Yes, TMPG06-20-1HE3_A/B is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling. Its 185 °C max junction temperature and robust construction make it suitable for engine compartment and chassis-mounted automotive modules.
What does the "HE3_A/B" suffix indicate in TMPG06-20-1HE3_A/B?
The "HE3" suffix denotes RoHS-compliant matte tin plating meeting JESD 201 Class 2 whisker resistance, while "A/B" specifies the revision code per Vishay's internal manufacturing control. Both revisions share identical electrical specifications, thermal ratings, and mechanical dimensions per Document Number 88404.
Can TMPG06-20-1HE3_A/B be used in bidirectional protection configurations?
No - TMPG06-20-1HE3_A/B is unidirectional only, with cathode marked by a color band. For bidirectional AC or dual-polarity DC protection, a separate pair of unidirectional devices or a dedicated bidirectional TVS (e.g., SMBJ20CA) must be used; this part is not rated for reverse conduction beyond its specified clamping curve.
What is the maximum clamping voltage of TMPG06-20-1HE3_A/B under full-rated surge?
The maximum clamping voltage (VC) of TMPG06-20-1HE3_A/B is 27.7 V at its rated peak pulse current of 14.4 A (10/1000 µs waveform). This value is guaranteed across temperature and lifetime, ensuring protected circuits remain within safe operating limits during standardized surge events like ISO 7637-2 Pulse 5a.
