Product details
Overview
TMPG06-43HE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. It delivers 400 W peak pulse power (10/1000 µs), clamps at 59.3 V under 6.7 A peak pulse current, and operates across -65 °C to +185 °C junction temperature - enabling use in engine control units and high-temperature sensor interfaces.
For engineers reviewing the TMPG06-43HE3/73 datasheet, TMPG06-43HE3/73 pinout, TMPG06-43HE3/73 application, or TMPG06-43HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 36.8 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 automated SMT assembly.
Technical Context
This TVS diode uses a passivated silicon junction in a molded epoxy MPG06 case, optimized for fast response (<1 ns) and low incremental resistance to limit voltage overshoot during inductive switching transients. Its unidirectional polarity and color-band cathode marking support clear PCB orientation in DC-biased protection paths.
The device meets JESD 201 Class 2 whisker resistance and JESD 22-B106 solder dip requirements (275 °C, 10 s), confirming suitability for high-reliability reflow and wave-solder processes. Thermal derating follows a defined curve down to zero power at 185 °C junction temperature, with 1.0 W steady-state dissipation on infinite heatsink at 75 °C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 400 W - sustains repetitive surge events in automotive load-dump and ISO 7637-2 compliant circuits |
| Stand-off Voltage (VWM) | 36.8 V - blocks normal operating voltage up to 36.8 V while remaining non-conductive |
| Breakdown Voltage (VBR) | 40.9–45.2 V at 1 mA - initiates clamping before downstream ICs exceed absolute maximum ratings |
| Clamping Voltage (VC) | 59.3 V at 6.7 A IPPM - limits transient voltage seen by protected MOSFETs or microcontrollers |
| Operating Temperature Range | -65 °C to +185 °C - supports under-hood automotive placement without thermal derating loss |
| AEC-Q101 Qualified | Validated for automotive electronics per stress test requirements including HTGB, H3TRB, and TCT |
| Package | MPG06 - axial-leaded, RoHS-compliant, UL 94 V-0 rated epoxy case with matte tin-plated leads |
Pinout & Package
MPG06 is an axial-leaded package with cathode identified by a color band. Leads are matte tin-plated, solderable per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 2 for whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in unidirectional configuration | Connected to protected circuit's ground or low-side return path for clamp-to-rail operation |
| Cathode | Negative terminal; marked with color band | Connected to power rail (e.g., 24 V battery line) to shunt transients to ground when VRM exceeded |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables protection against severe ISO 7637-2 Pulse 5a/b load-dump events in 24 V systems |
| AEC-Q101 qualification | Confirms reliability for automotive ECUs, body control modules, and ADAS power supplies |
| 185 °C max junction temperature | Supports direct mounting near heat-generating components without external thermal relief |
| Low 1.0 µA reverse leakage at VWM | Minimizes standby power loss in always-on vehicle networks (e.g., CAN wake-up lines) |
| UL 94 V-0 molding compound | Meets flammability safety requirements for enclosed automotive and industrial enclosures |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | Same 43 V breakdown, but SMA package (SMT); lower 400 W rating applies only to 10/1000 µs waveform with 0.01 % duty cycle | Requires PCB redesign for surface-mount layout; lacks AEC-Q101 qualification and 185 °C TJ rating | Select when board space is constrained and automotive qualification is not required |
| P6SMB43A | Same VBR range and 400 W rating, but DO-214AA package; higher 1.0 µA leakage at VWM vs. TMPG06-43HE3/73's 1.0 µA (identical), but no AEC-Q101 validation | Used in industrial power supplies where extended temperature operation is not mandated | Choose for cost-sensitive non-automotive designs needing proven surge handling without qualification overhead |
Compared with SMAJ43A and P6SMB43A, TMPG06-43HE3/73 provides verified AEC-Q101 compliance, axial-leaded through-hole assembly compatibility, and guaranteed operation up to +185 °C - making it the only option qualified for under-hood automotive deployment without thermal derating penalties.

FAQ
What is the clamping voltage of TMPG06-43HE3/73 at its rated peak pulse current?
The TMPG06-43HE3/73 has a maximum clamping voltage (VC) of 59.3 V when subjected to its specified peak pulse current (IPPM) of 6.7 A using a 10/1000 µs waveform. This value is measured per Figure 3 in the Vishay datasheet 88404 and defines the upper voltage limit imposed on protected circuitry during transient events. The TMPG06-43HE3/73 maintains this clamping performance across its full operating temperature range.
Is TMPG06-43HE3/73 qualified for automotive applications?
Yes, TMPG06-43HE3/73 is explicitly AEC-Q101 qualified per the Vishay datasheet revision 17-Sep-2021. It has passed stress tests including high-temperature gate bias (HTGB), highly accelerated temperature-humidity bias (H3TRB), and temperature cycling (TCT). This qualification confirms its suitability for automotive powertrain, body, and chassis systems where reliability under thermal and electrical stress is mandatory. TMPG06-43HE3/73 is not just automotive-capable - it is automotive-qualified.
What does the "HE3/73" suffix indicate in TMPG06-43HE3/73?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, while "73" identifies the specific tape-and-reel packaging configuration: 5500 units per 13-inch diameter reel in paper tape. Both markings appear in Vishay's official ordering information table and confirm conformance to JEDEC standards for solderability and mechanical handling. TMPG06-43HE3/73 is fully traceable to these specifications.
Can TMPG06-43HE3/73 be used in bidirectional protection configurations?
No, TMPG06-43HE3/73 is unidirectional only, as confirmed in the Vishay datasheet features section and electrical characteristics table. It conducts only when cathode voltage exceeds anode voltage by ≥VBR; it does not suppress negative-going transients on AC or bipolar rails. For bidirectional protection, a separate device such as SMBJ43CA or two back-to-back unidirectional TVS diodes would be required. TMPG06-43HE3/73 must be oriented with its cathode band toward the protected power rail.
What is the maximum steady-state power dissipation for TMPG06-43HE3/73?
The TMPG06-43HE3/73 has a maximum steady-state power dissipation (PD) of 1.0 W when mounted on an infinite heatsink at a lead temperature (TL) of 75 °C, as specified in the "Maximum Ratings" table. This rating decreases linearly above 75 °C per the derating curve in Figure 5 of datasheet 88404, reaching zero at 185 °C junction temperature. TMPG06-43HE3/73 is not intended for continuous power dissipation - its design focus is transient energy absorption.
