Product details
Overview
TMPG06-20AHE3/73 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 delivers 400 W peak pulse power (10/1000 µs), clamps at 27.7 V under 14.4 A peak pulse current, and operates across -65 °C to +185 °C junction temperature - qualified to AEC-Q101 for under-hood automotive electronics.
For engineers reviewing the TMPG06-20AHE3/73 datasheet, TMPG06-20AHE3/73 pinout, TMPG06-20AHE3/73 application, or TMPG06-20AHE3/73 equivalent, key selection criteria include its 19.0–21.0 V breakdown voltage range, 17.0 V stand-off voltage, low 1.0 µA reverse leakage at VWM, 3.5 V max forward voltage at 25 A, and MPG06 package compatibility with high-reliability PCB assembly processes.
Technical Context
This TVS diode employs a passivated silicon junction in a molded epoxy MPG06 case, optimized for fast response (<1 ns) and low incremental resistance to limit transient-induced voltage overshoot during inductive switching events. Its AEC-Q101 qualification confirms performance under accelerated temperature cycling, humidity bias, and mechanical shock conditions required for automotive ECUs and sensor modules.
The device sustains 40 A non-repetitive forward surge current (8.3 ms half-sine) and derates linearly above 25 °C ambient, maintaining 1.0 W power dissipation at 75 °C lead temperature. Clamping behavior is characterized at IPPM = 14.4 A, where VC = 27.7 V ensures MOSFET gate drivers and CAN transceivers remain within safe operating limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 19.0 V / 21.0 V - Ensures reliable triggering above 17.0 V system stand-off voltage while avoiding false trips during normal operation. |
| VWM | 17.0 V - Maximum continuous reverse working voltage compatible with 12 V automotive systems and industrial 15 V rails. |
| PPPM | 400 W - Peak pulse power handling for 10/1000 µs transients, sufficient for ISO 7637-2 Pulse 1/2a/5a compliance testing. |
| IPPM | 14.4 A - Peak pulse current at which clamping voltage reaches 27.7 V, defining protection margin for downstream ICs. |
| VC @ IPPM | 27.7 V - Clamped voltage level that safeguards 30 V-rated MOSFETs and 5 V/3.3 V logic interfaces during ESD or load dump. |
| TJ max | +185 °C - Enables placement near heat sources (e.g., power converters) without thermal derating penalties in engine control units. |
| Polarity | Unidirectional - Protects against positive-going transients only; requires external series resistor or complementary diode for bidirectional coverage. |
Pinout & Package
Package: MPG06 - axial-leaded, molded epoxy case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards; cathode indicated by color band; UL 94 V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (banded end) | Current entry point during forward conduction | Connected to ground or low-side reference; enables clamping of positive transients to GND when cathode is tied to protected line. |
| Cathode (color-banded end) | Transient voltage sensing and clamping node | Connected directly to the line being protected (e.g., 12 V battery rail); conducts avalanche current to anode during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HAST, and mechanical shock - suitable for engine control, ADAS, and body electronics. |
| 400 W peak pulse power (10/1000 µs) | Withstands ISO 7637-2 load-dump surges up to 120 V/100 ms without degradation, supporting long-term field deployment in harsh environments. |
| Low 1.0 µA reverse leakage @ VWM | Minimizes standby power loss in always-on systems such as telematics and smart sensors, preserving battery life in 12 V vehicle architectures. |
| Fast response time (<1 ns) | Clamps transients before they propagate through sensitive analog front-ends or microcontroller I/O pins, preventing latch-up or data corruption. |
| Solder dip tolerance: 275 °C / 10 s | Supports wave soldering and reflow profiles used in high-volume automotive PCB assembly without delamination or parameter shift. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ20A | Same VWM (17.1 V), lower PPPM (600 W), SMC package (surface-mount), higher VC (32.4 V at 12.3 A) | Preferred for space-constrained PCBs; less effective clamping margin for 24 V systems due to higher VC | Select SMBJ20A only if board real estate is critical and clamping voltage margin >4.7 V is acceptable. |
| 1.5KE20A | Higher VBR range (18.2–21.8 V), same PPPM (400 W), DO-201 package (larger axial leaded), VF = 3.5 V, TJ max = 175 °C | Legacy replacement with lower thermal rating; not AEC-Q101 qualified; unsuitable for new automotive designs | Use 1.5KE20A only for cost-sensitive industrial retrofits where AEC-Q101 is not mandated. |
Compared with SMBJ20A and 1.5KE20A, TMPG06-20AHE3/73 offers superior thermal endurance (+185 °C vs. +175 °C), automotive qualification, and tighter VBR tolerance (±5 % vs. ±10 %), making it the preferred choice for next-generation automotive and high-reliability industrial designs requiring validated long-term stability.

FAQ
What is the breakdown voltage range for TMPG06-20AHE3/73?
The TMPG06-20AHE3/73 has a guaranteed breakdown voltage range of 19.0 V to 21.0 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight ±5 % tolerance ensures predictable clamping onset across temperature and production lots, critical for protecting 12 V automotive electronics without nuisance triggering during cold-cranking dips.
Is TMPG06-20AHE3/73 suitable for automotive applications?
Yes, TMPG06-20AHE3/73 is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C junction temperature. Its construction meets automotive reliability requirements including temperature cycling, humidity bias, and mechanical shock - making it appropriate for engine control units, body control modules, and ADAS sensor power rails where long-term field reliability is mandatory.
What does the "HE3" suffix indicate in TMPG06-20AHE3/73?
The "HE3" suffix in TMPG06-20AHE3/73 denotes RoHS-compliant, matte tin-plated leads that meet JESD 201 Class 2 whisker resistance requirements and J-STD-002/JESD 22-B102 solderability standards. It also signifies AEC-Q101 qualification and UL 94 V-0 flammability rating of the MPG06 epoxy molding compound - essential for high-reliability automotive and industrial use.
How does TMPG06-20AHE3/73 compare to standard 1N400x rectifiers in surge protection?
TMPG06-20AHE3/73 is not a rectifier but a purpose-built TVS diode with optimized avalanche characteristics, 400 W pulse power, and sub-nanosecond response - unlike 1N400x devices, which lack controlled clamping, have higher VF, and degrade rapidly under repetitive transients. Using TMPG06-20AHE3/73 instead of 1N400x prevents catastrophic failure during ISO 7637-2 testing and ensures repeatable protection performance over product lifetime.
Can TMPG06-20AHE3/73 be used in bidirectional protection configurations?
No - TMPG06-20AHE3/73 is unidirectional only, with cathode marked by a color band. For bidirectional protection, two TMPG06-20AHE3/73 devices must be connected in series opposition (anode-to-anode), or a dedicated bidirectional TVS like SMAJ20A should be selected. Misusing a single unidirectional device for negative transients risks permanent breakdown and short-circuit failure.
