Product details
Overview
TPSMP7.5A-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade ESD and surge protection. It features 7.13 V to 7.88 V breakdown voltage (VBR), 6.40 V standoff voltage (VWM), 150 µA max reverse leakage at VWM, 500 A peak pulse current (IPPM), and clamps to 26.5 V at IPPM, protecting signal lines in engine control units and sensor interfaces.
For engineers reviewing the TPSMP7.5A-E3/84A datasheet, TPSMP7.5A-E3/84A pinout, TPSMP7.5A-E3/84A application, or TPSMP7.5A-E3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 300 W peak pulse power rating (10/1000 µs), 1.0 mm profile, matte tin-plated terminals, and RoHS/WEEE compliance for automotive electronics design.
Technical Context
The TPSMP7.5A-E3/84A uses patented PAR oxide passivated chip construction to deliver low incremental surge resistance and excellent clamping performance under fast transient events. Its unidirectional configuration enables integration into DC-biased signal paths where reverse polarity protection is not required.
Designed for surface-mount placement on PCBs with 5.0 × 5.0 mm copper pads per terminal, it meets MSL Level 1 per J-STD-020C and withstands solder dip at 260 °C for 40 seconds. Junction temperature range spans –65 °C to +185 °C, supporting under-hood automotive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | DO-214AC (SMA) package; 1.9 mm height; 400 W PPPM; 500 A IPPM; VC = 12.4 V | Higher clamping ratio but larger footprint; less suitable for ultra-thin modules | Choose SMAJ7.5A when board height budget allows and higher surge margin is needed over compactness |
| TPSMA6.8A | Same DO-220AA package; lower VBR (6.45–7.14 V); same 300 W rating; VC = 10.5 V | Better clamping for 5 V systems but reduced margin against overvoltage in 12 V domains | Choose TPSMA6.8A only if system operates below 6.4 V nominal and requires tighter clamping voltage |
Compared with SMAJ7.5A and TPSMA6.8A, the TPSMP7.5A-E3/84A delivers optimal balance of ultra-low profile (1.0 mm), AEC-Q101 readiness, and 26.5 V clamping for 12 V automotive signal lines-making it preferred for space-constrained, high-reliability modules where thermal and mechanical envelope are critical.

FAQ
What is the breakdown voltage tolerance of the TPSMP7.5A-E3/84A?
The TPSMP7.5A-E3/84A has a specified breakdown voltage range of 7.13 V to 7.88 V at 10 mA test current (IT), representing ±5% tolerance around the nominal 7.5 V rating. This tight VBR window ensures consistent triggering behavior across production lots and supports reliable design margins in 12 V automotive systems where precise clamping onset is critical.
Is the TPSMP7.5A-E3/84A AEC-Q101 qualified?
No-the TPSMP7.5A-E3/84A carries the "E3" suffix indicating commercial-grade qualification. For AEC-Q101 compliance, the HE3-suffix variant (e.g., TPSMP7.5A-HE3/84A) must be selected. The TPSMP7.5A-E3/84A shares identical electrical specs and DO-220AA packaging but lacks the extended reliability testing required for automotive qualification.
What is the maximum clamping voltage of the TPSMP7.5A-E3/84A under surge conditions?
The TPSMP7.5A-E3/84A clamps to a maximum of 26.5 V when subjected to its rated 500 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This clamping voltage is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
Can the TPSMP7.5A-E3/84A be used in bidirectional configurations?
No-the TPSMP7.5A-E3/84A is strictly unidirectional and must be installed with correct polarity (cathode band oriented toward the higher-potential side). Bidirectional protection requires separate devices such as the TPSMP7.5CA series or dual-diode configurations; using TPSMP7.5A-E3/84A in reverse orientation risks permanent failure due to avalanche breakdown in the wrong direction.
What is the thermal derating behavior of the TPSMP7.5A-E3/84A above 25 °C ambient?
The TPSMP7.5A-E3/84A follows a linear derating curve from 100 % power at 25 °C ambient down to 0 % at 175 °C, as shown in Figure 2 of Vishay document 88937. At 100 °C ambient, its peak pulse power capability drops to approximately 60 % of the rated 300 W, requiring system-level thermal analysis when deployed in high-temperature zones like engine compartments.
