Product details
Overview
TMPG06-6.8HE3/54 from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor diode in MPG06 package, featuring 6.12 V to 7.48 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), 1.0 W steady-state power dissipation, 40 A peak forward surge current, and AEC-Q101 qualification for engine control units and sensor protection circuits.
For engineers reviewing the TMPG06-6.8HE3/54 datasheet, TMPG06-6.8HE3/54 pinout, TMPG06-6.8HE3/54 application, or TMPG06-6.8HE3/54 equivalent, key selection criteria include clamping voltage (27.8 V at 1000 A), stand-off voltage (10.0 V), reverse leakage (5.5 µA at 25 °C), junction temperature range (–65 °C to +185 °C), and RoHS-compliant matte tin-plated leads.
Technical Context
This TVS diode uses patented PAR® construction for stable clamping under repetitive transients and operates with low incremental surge resistance to minimize voltage overshoot during fast-rising ESD or load-dump events. Its unidirectional polarity and 10.0 V stand-off voltage make it suitable for DC-biased signal and power line protection.
The device delivers 27.8 V maximum clamping voltage at 1000 A peak pulse current (10/1000 µs), with 0.057 %/°C temperature coefficient of VBR, enabling predictable performance across automotive thermal ranges. It is rated for solder dip at 260 °C for 40 s and passes JESD201 Class 2 whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.8A-E3/5AT | Lower PPPM (400 W same), but higher VC (11.5 V), smaller SMA package, non-automotive grade | Not AEC-Q101 qualified; unsuitable for under-hood automotive use | Select when cost-sensitive consumer designs require basic ESD protection without automotive reliability |
| 1.5SMC6.8A | Same VBR range and PPPM, but larger SMC package, higher IFSM (100 A), no HE3 whisker rating | Lacks JESD201 Class 2 compliance; not recommended for long-life sealed modules | Choose for high-surge industrial power supplies where board space allows larger footprint |
Compared with SMAJ6.8A-E3/5AT and 1.5SMC6.8A, the TMPG06-6.8HE3/54 uniquely combines AEC-Q101 qualification, JESD201 Class 2 whisker resistance, and MPG06's optimized thermal path for sustained high-temperature operation-critical for automotive ECU longevity.

FAQ
What is the breakdown voltage tolerance for TMPG06-6.8HE3/54?
The TMPG06-6.8HE3/54 has a minimum breakdown voltage (VBR) of 6.12 V and a maximum of 7.48 V at 10 mA test current, yielding a ±10% tolerance around the nominal 6.8 V rating. This range ensures consistent turn-on behavior across production lots while accommodating thermal and process variation. The device maintains this specification across its full operating temperature range.
Is TMPG06-6.8HE3/54 suitable for bidirectional transient protection?
No, TMPG06-6.8HE3/54 is unidirectional only, as confirmed in the Vishay datasheet Document Number 88404. It must be connected with cathode toward the protected line and anode to ground. For bidirectional AC-line protection, a separate symmetric TVS pair or dedicated bidirectional device such as SMBJ6.8CA is required. Using TMPG06-6.8HE3/54 in reverse bias beyond VWM risks permanent damage.
What does the HE3/54 suffix indicate in TMPG06-6.8HE3/54?
The HE3 suffix denotes RoHS-compliant, high-reliability automotive grade with JESD201 Class 2 whisker resistance; the /54 indicates packaging in 13" diameter paper tape and reel with 5500 units per reel. This configuration ensures compatibility with high-speed automated placement equipment and meets stringent automotive supply chain traceability requirements for the TMPG06-6.8HE3/54.
Does TMPG06-6.8HE3/54 require a heatsink for 1.0 W continuous operation?
No, the TMPG06-6.8HE3/54 achieves its 1.0 W power dissipation rating at lead temperature (TL) of 75 °C without external heatsinking, as specified in Figure 5 of the datasheet. Its MPG06 package provides sufficient thermal conduction through leads to PCB copper; however, layout should include ≥10 mm² of 2-oz copper connected to both terminals to maintain TJ ≤ 185 °C under worst-case ambient conditions.
How does the temperature coefficient affect TMPG06-6.8HE3/54 performance in automotive applications?
The TMPG06-6.8HE3/54 has a VBR temperature coefficient of +0.057 %/°C, meaning breakdown voltage increases ~0.4 V over a 70 °C rise (e.g., from 25 °C to 95 °C). This positive drift ensures clamping remains effective at elevated under-hood temperatures and avoids premature conduction during hot-cranking, preserving system reliability across the full –65 °C to +185 °C junction range.
