Product details
Overview
TMPG06-9.1HE3/73 from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor diode in MPG06 package, featuring 9.1 V breakdown voltage (VBR min/max: 8.19–10.0 V), 400 W peak pulse power (10/1000 µs), 21.7 V clamping voltage at 50 A IPPM, and AEC-Q101 qualification for engine control units and sensor protection.
For engineers reviewing the TMPG06-9.1HE3/73 datasheet, TMPG06-9.1HE3/73 pinout, TMPG06-9.1HE3/73 application, or TMPG06-9.1HE3/73 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating to +185 °C, RoHS-compliant matte tin leads, and compatibility with J-STD-002 solderability standards.
Technical Context
This TVS diode uses patented PAR® construction for low incremental surge resistance and fast response time (<1 ns), enabling robust suppression of inductive switching transients in automotive power electronics. Its unidirectional polarity and 1.0 VWM standoff voltage support DC-biased signal and power line protection.
The device operates across –65 °C to +185 °C junction temperature range with 0.068 %/°C VBR temperature coefficient, and maintains stable clamping up to 50 A peak pulse current per 10/1000 µs waveform-critical for protecting MOSFETs and microcontrollers in harsh environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 8.19 V / 10.0 V - Ensures reliable conduction onset above normal operating voltage while avoiding false triggering. |
| VC @ IPPM | 21.7 V at 50 A - Limits downstream voltage stress during 10/1000 µs surges to safe levels for 3.3 V/5 V ICs. |
| PPPM | 400 W - Sustains high-energy transients common in automotive load-dump and ISO 7637-2 pulse 5a events. |
| IFSM | 40 A - Withstands 8.3 ms half-sine surge without degradation, supporting motor driver and alternator interface designs. |
| TJ max. | +185 °C - Enables placement near heat sources (e.g., power modules) without thermal derating penalties. |
| VWM | 1.0 V - Matches low-voltage logic and sensor supply rails where minimal leakage and tight standoff are essential. |
| Leakage @ VWM | 10 µA at 25 °C - Minimizes standby power loss in battery-critical systems like body control modules. |
Pinout & Package
Package: MPG06 molded epoxy case, UL 94 V-0 rated, with matte tin-plated leads compliant with J-STD-002 and JESD22-B102. Cathode denoted by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected circuit ground or low-side return path; enables unidirectional clamping to ground. |
| Cathode | Current exit point during reverse-biased clamping | Connected to protected line (e.g., CAN_H, LIN, sensor VCC); sinks surge current to ground when VLINE exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR® construction | Reduces incremental surge resistance for tighter VC tolerance and lower let-through energy during fast transients. |
| AEC-Q101 qualified | Validated for automotive under-hood applications including powertrain and ADAS sensor interfaces with zero infant mortality. |
| RoHS-compliant HE3 suffix | Meets JESD201 Class 2 whisker resistance, ensuring long-term reliability in vibration-prone automotive harnesses. |
| 185 °C max junction temperature | Supports direct mounting on high-temperature PCB zones (e.g., near ignition coils or DC-DC converters) without heatsinking. |
| 400 W peak pulse rating | Handles repeated ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 5a (load dump) without parameter shift. |
Applications
| Engine Control Unit Protection | Automotive Sensor Interface |
|---|---|
|
Use Scenario: Protecting MCU I/O pins and analog front-ends from load-dump transients induced by fuel injector or solenoid coil de-energization. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between protected signal line and chassis ground. Use Value: Clamps 10/1000 µs surges to ≤21.7 V, preventing latch-up or gate oxide damage in 5 V tolerant microcontrollers. |
Use Scenario: Safeguarding LIN bus transceivers and analog sensor outputs (e.g., oxygen, pressure) against ESD and switching noise. IC Role / Device Role / Timing Role: Standoff voltage of 1.0 V ensures no interference with 12 V nominal LIN signaling while suppressing >100 V spikes. Use Value: 10 µA leakage at VWM avoids signal offset errors in precision ratiometric sensor bridges. |
| Body Control Module Power Rail | Electric Power Steering Motor Driver |
|
Use Scenario: Decoupling 12 V supply lines feeding door lock actuators, window lift motors, and lighting drivers. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing repetitive inductive kickback from brushed DC motor commutation. Use Value: 40 A IFSM rating supports 8.3 ms surge survival during simultaneous actuator activation events. |
Use Scenario: Protecting half-bridge MOSFET gates and bootstrap circuits from Miller-induced voltage overshoot during high-speed PWM switching. IC Role / Device Role / Timing Role: Low-capacitance unidirectional clamp referenced to local ground, minimizing signal distortion on gate drive paths. Use Value: Fast <1 ns response time prevents gate oxide breakdown before controller overvoltage protection triggers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ9.0A | Lower PPPM (400 W same), but VC = 14.4 V @ 28.6 A; smaller SMA package (lower thermal mass). | Limited to ambient-temperature industrial use; not AEC-Q101 qualified or rated for TJ = 185 °C. | Select when cost and board space outweigh automotive qualification and high-temperature operation. |
| TPSMA6.8A | VBR = 6.8 V (min/max 6.45–7.14 V); VC = 11.5 V @ 34.7 A; same MPG06 package and AEC-Q101 grade. | Better suited for 5 V rail protection where lower clamping voltage is critical, but insufficient for 12 V system transients. | Choose for 5 V logic or USB-C PD port protection where tighter VC and lower VBR improve margin. |
Compared with SMAJ9.0A and TPSMA6.8A, TMPG06-9.1HE3/73 uniquely combines AEC-Q101 qualification, +185 °C operation, and 9.1 V VBR optimized for 12 V automotive systems-making it the only option validated for under-hood ECU and sensor node deployment.

FAQ
What is the clamping voltage of TMPG06-9.1HE3/73 at its rated peak pulse current?
The clamping voltage (VC) of TMPG06-9.1HE3/73 is 21.7 V at 50 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable overvoltage limiting for downstream 5 V and 12 V components. The TMPG06-9.1HE3/73 maintains this clamping performance across its full operating temperature range.
Is TMPG06-9.1HE3/73 qualified for automotive applications?
Yes, TMPG06-9.1HE3/73 is AEC-Q101 qualified and designated as high-reliability/automotive grade (base P/N HE3). It meets stringent requirements for temperature cycling, humidity, mechanical shock, and surge endurance-validated for under-hood use in ECUs, body control modules, and sensor nodes. The TMPG06-9.1HE3/73 datasheet explicitly references AEC-Q101 compliance in its mechanical data section.
What does the HE3 suffix indicate on TMPG06-9.1HE3/73?
The HE3 suffix on TMPG06-9.1HE3/73 denotes RoHS compliance, high-reliability construction, and qualification to JESD201 Class 2 for tin whisker resistance. It confirms matte tin-plated leads that meet J-STD-002 solderability standards and 260 °C solder dip (40 s) capability-critical for automotive reflow and wave soldering processes. The TMPG06-9.1HE3/73 HE3 marking is defined in the official Vishay document 88404.
What is the maximum operating junction temperature for TMPG06-9.1HE3/73?
The maximum operating junction temperature (TJmax) for TMPG06-9.1HE3/73 is +185 °C, as specified in the "Primary Characteristics" table and confirmed in the "Maximum Ratings" section of the Vishay datasheet. This allows direct placement near heat-generating components such as power MOSFETs or DC-DC converters without thermal derating. The TMPG06-9.1HE3/73 sustains full electrical performance up to this limit.
How does TMPG06-9.1HE3/73 differ from the TMPG06-9.1A variant?
TMPG06-9.1HE3/73 has a breakdown voltage range of 8.19–10.0 V and 10 µA leakage at VWM, whereas TMPG06-9.1A specifies 8.65–9.55 V VBR and 10 µA leakage at VWM. The "A" suffix indicates tighter VBR tolerance, but both share identical package, power rating, clamping voltage, and AEC-Q101 qualification. The TMPG06-9.1HE3/73 is the standard-grade version optimized for cost-sensitive automotive volume production.
