Product details
Overview
TMPG06-9.1AHE3/73 from Vishay General Semiconductor is an automotive-grade unidirectional transient voltage suppressor diode in MPG06 package, with 9.1 V nominal breakdown voltage (VBR = 8.65–9.55 V), 400 W peak pulse power (10/1000 µs), 22.4 V clamping voltage at 50 A, and AEC-Q101 qualification for engine control units and sensor protection.
For engineers reviewing the TMPG06-9.1AHE3/73 datasheet, TMPG06-9.1AHE3/73 pinout, TMPG06-9.1AHE3/73 application, or TMPG06-9.1AHE3/73 equivalent, key selection criteria include clamping voltage at rated IPPM, temperature coefficient of VBR (0.068 %/°C), junction temperature range (−65 °C to +185 °C), and RoHS-compliant HE3 suffix meeting JESD201 Class 2 whisker test.
Technical Context
This TVS diode uses Vishay's patented PAR® construction for stable high-temperature operation and low incremental surge resistance. It delivers 400 W peak pulse power under 10/1000 µs waveform with 0.01 % duty cycle, and exhibits fast response time (<1 ns) and excellent clamping linearity across its operating temperature range.
Designed for automotive environments, TMPG06-9.1AHE3/73 features a matte tin-plated lead finish compliant with J-STD-002 and JESD22-B102, and operates reliably up to TJ = 185 °C. Its unidirectional polarity and color-band cathode marking align with standard PCB layout conventions for reverse-polarity protection.

Use Value: 0.068 %/°C VBR tempco maintains consistent trigger threshold across cabin temperature extremes (−40 °C to +85 °C). |
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 VBR min/max = 10.0–11.1 V; no AEC-Q101 qualification | Rated for industrial/commercial use only; not validated for automotive thermal cycling or humidity testing | Select when cost sensitivity outweighs automotive qualification requirements and VBR tolerance margin permits higher trip point |
| TPSMA6.8A | VBR = 7.13–7.88 V; same PPPM, AEC-Q101 qualified; lower clamping voltage (20.8 V @ 50 A) | Better suited for 5 V rail protection where tighter VBR alignment reduces risk of false triggering | Choose for 5 V systems requiring tighter breakdown control and identical automotive reliability assurance |
Compared with SMAJ9.0A and TPSMA6.8A, TMPG06-9.1AHE3/73 offers optimal balance of 9.1 V nominal breakdown, AEC-Q101 validation, and 22.4 V clamping-making it preferred for 12 V automotive subsystems where precise trip voltage and under-hood thermal resilience are critical.

FAQ
What is the breakdown voltage range of the TMPG06-9.1AHE3/73?
The TMPG06-9.1AHE3/73 has a guaranteed breakdown voltage range of 8.65 V to 9.55 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This tight VBR window ensures consistent clamping behavior across production lots and supports reliable protection of 9 V nominal circuits without premature conduction or insufficient surge suppression.
Is the TMPG06-9.1AHE3/73 qualified for automotive applications?
Yes, the TMPG06-9.1AHE3/73 is AEC-Q101 qualified and designated as high-reliability/automotive grade (Base P/NHE3). It undergoes stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life-validating its suitability for engine control, transmission, and chassis electronics where failure is not acceptable.
What does the HE3 suffix indicate on the TMPG06-9.1AHE3/73?
The HE3 suffix on TMPG06-9.1AHE3/73 denotes RoHS compliance, high-reliability construction, and qualification to JESD201 Class 2 for tin whisker resistance. This ensures long-term solder joint integrity under thermal cycling conditions typical in automotive and industrial deployments, distinguishing it from commercial-grade variants.
What is the maximum clamping voltage of the TMPG06-9.1AHE3/73 at rated peak pulse current?
The TMPG06-9.1AHE3/73 clamps to a maximum of 22.4 V at its rated peak pulse current of 50 A (10/1000 µs waveform). This value is measured under standardized test conditions and defines the upper voltage limit imposed on protected circuitry during worst-case surge events, enabling accurate system-level overvoltage margin analysis.
Can the TMPG06-9.1AHE3/73 be used in bidirectional configurations?
No, the TMPG06-9.1AHE3/73 is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts only when cathode voltage exceeds anode voltage by ≥VBR; for AC or bipolar transient protection, a separate bidirectional device such as SMBJ9.0CA must be selected instead of relying on this part.
