Overview

TMPG06-8.2AHE3/54 from Vishay General Semiconductor is an automotive-grade unidirectional transient voltage suppressor diode in MPG06 package, with 8.2 V nominal breakdown voltage (V_BR = 7.79–8.61 V), 400 W peak pulse power (10/1000 µs), 12.1 V clamping voltage at 200 A, and AEC-Q101 qualification for engine control units and sensor protection.

For engineers reviewing the TMPG06-8.2AHE3/54 datasheet, TMPG06-8.2AHE3/54 pinout, TMPG06-8.2AHE3/54 application, or TMPG06-8.2AHE3/54 equivalent, key selection criteria include clamping voltage under 200 A surge, junction temperature rating up to +185 °C, RoHS-compliant matte tin plating, and JESD201 Class 2 whisker resistance.

Technical Context

This TVS diode uses patented PAR® construction for stable clamping under repetitive transients and operates exclusively in unidirectional polarity. Its low incremental surge resistance and fast response time enable effective suppression of inductive switching spikes on 12 V automotive rails.

The device features a molded epoxy MPG06 case rated UL 94 V-0, color-banded cathode marking, and is qualified per AEC-Q101 for high-reliability automotive environments-supporting operation from −65 °C to +185 °C with 0.065 %/°C V_BR temperature coefficient.

FAQ

What is the clamping voltage of TMPG06-8.2AHE3/54 at its rated peak pulse current?

The TMPG06-8.2AHE3/54 has a maximum clamping voltage (V_C) of 12.1 V at 200 A peak pulse current (I_PPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream ICs remain within safe overvoltage limits during surge events. The clamping performance is guaranteed across the full operating temperature range and is integral to its AEC-Q101 qualification.

Is TMPG06-8.2AHE3/54 suitable for automotive under-hood applications?

Yes, TMPG06-8.2AHE3/54 is explicitly qualified to AEC-Q101 and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and camera power supplies. Its MPG06 package meets UL 94 V-0 flammability requirements and its matte tin leads comply with JESD201 Class 2 whisker testing-key criteria for high-reliability automotive deployment.

What does the "HE3/54" suffix mean in TMPG06-8.2AHE3/54?

The "HE3" suffix denotes RoHS-compliant, high-reliability/automotive-grade construction per Vishay's internal specification, including JESD201 Class 2 whisker resistance. The "/54" indicates packaging in 13-inch paper tape and reel with a base quantity of 5500 units. This ordering code ensures traceable, automotive-qualified material with verified solderability and long-term stability.

How does TMPG06-8.2AHE3/54 differ from the non-A version (TMPG06-8.2HE3/54)?

The "A" in TMPG06-8.2AHE3/54 signifies tighter parametric tolerances and full AEC-Q101 qualification, including extended temperature cycling, high-temperature operating life, and mechanical shock testing. The non-A version lacks this automotive validation and exhibits wider V_BR spread (7.38–9.02 V vs. 7.79–8.61 V) and higher clamping voltage (12.5 V vs. 12.1 V), making TMPG06-8.2AHE3/54 the only version approved for safety-critical automotive use.

Can TMPG06-8.2AHE3/54 be used in bidirectional configurations?

No, TMPG06-8.2AHE3/54 is unidirectional only, as confirmed in the Vishay datasheet Document Number 88404. It must be oriented with the cathode band toward the protected circuit's ground reference. For bidirectional protection, two devices in series opposition or a dedicated bidirectional TVS (e.g., SMBJ8.0CA) would be required-neither of which applies to the electrical or mechanical design of TMPG06-8.2AHE3/54.
