Product details
Overview
TPSMP7.5AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features a 7.13 V to 7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 300 W peak pulse power (10/1000 µs), 500 A peak pulse current (IPPM), and clamps to ≤26.5 V at rated surge - ideal for automotive sensor line and microcontroller I/O protection.
For engineers reviewing the TPSMP7.5AHM3/84A datasheet, TPSMP7.5AHM3/84A pinout, TPSMP7.5AHM3/84A application, or TPSMP7.5AHM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction rating, MSL Level 1 moisture sensitivity, 1.0 mm profile, and uni-directional polarity with cathode band marking - all critical for under-hood automotive and space-constrained industrial designs.
Technical Context
The TPSMP7.5AHM3/84A employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns). Its unidirectional architecture enables integration into DC-biased signal or power rails where reverse conduction must be blocked during normal operation.
Rated for TJ = -65 °C to +185 °C and qualified per AEC-Q101, it supports automotive-grade reliability without derating up to 150 °C ambient. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements, with matte tin-plated leads solderable per J-STD-002 and JESD22-B102.
Key Specifications

IC Role / Device Role / Timing Role: Fast-clamping TVS on 5 V/9 V/15 V output rails, coordinated with primary-side OVP and secondary-side shunt regulators. Use Value: 300 W peak power rating sustains multiple 10/1000 µs pulses without parametric shift, meeting IEC 61000-4-5 Level 3 requirements. | Use Scenario: Protecting LIN bus nodes and LED driver control lines in door modules and lighting ECUs against battery reverse connection and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS on 12 V supply inputs and LIN data lines, leveraging cathode-band polarity for correct orientation in high-volume SMT assembly. Use Value: Halogen-free, RoHS-compliant HM3 suffix and JESD201 Class 2 whisker resistance ensure long-term reliability in humid, vibration-prone cabin environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | DO-214AC (SMA) package; 7.0 V VBR min, 200 W PPPM, 32.4 V VC @ 32.6 A | Lower surge rating and larger footprint; suitable only for non-automotive, lower-energy circuits | Select SMAJ7.0A only if board space allows larger package and surge requirements are ≤200 W |
| TPSMA6.8A | DO-214AC (SMA) package; 6.8 V VBR min, 400 W PPPM, 17.5 V VC @ 22.9 A | Higher PPPM but wider VC spread; not AEC-Q101 qualified | Choose TPSMA6.8A for cost-sensitive industrial designs where automotive qualification is unnecessary |
Compared with SMAJ7.0A and TPSMA6.8A, the TPSMP7.5AHM3/84A delivers superior power density (300 W in 1.0 mm height), guaranteed AEC-Q101 compliance, and tighter VC specification - making it the preferred choice for space-constrained, high-reliability automotive signal line protection.

FAQ
What is the breakdown voltage range of the TPSMP7.5AHM3/84A?
The TPSMP7.5AHM3/84A has a specified breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports robust design margins for 5 V and 6.4 V nominal rails. The value is confirmed in Vishay Document Number 88471, Table on page 2.
Is the TPSMP7.5AHM3/84A suitable for automotive applications?
Yes, the TPSMP7.5AHM3/84A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and body-control module applications. Its DO-220AA package meets MSL Level 1, and the HM3 suffix confirms halogen-free, RoHS-compliant construction - all verified in Vishay's official datasheet revision 22-Jul-16.
What is the clamping voltage of the TPSMP7.5AHM3/84A at its rated peak pulse current?
The TPSMP7.5AHM3/84A clamps to a maximum of 26.5 V at its rated peak pulse current (IPPM) of 500 A with a 10/1000 µs waveform. This value is measured under standardized test conditions (mounted on 5.0 mm × 5.0 mm copper pads) and guarantees protection headroom for 3.3 V and 5 V logic interfaces downstream of the device.
Does the TPSMP7.5AHM3/84A have polarity marking, and how is it identified?
Yes, the TPSMP7.5AHM3/84A uses a cathode band to indicate polarity - the banded end is the cathode terminal, which connects to the line being protected. This marking is visible on the DO-220AA molded case and aligns with JEDEC-standard orientation for unidirectional TVS diodes, ensuring correct placement during automated SMT assembly.
What packaging format is supplied for the TPSMP7.5AHM3/84A?
The TPSMP7.5AHM3/84A is supplied in 7-inch plastic tape and reel format with a base quantity of 3000 units per reel (package code 84A).
