Product details
Overview
TPSMP15AHM3/84A 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 14.3 V (min) to 15.8 V (max) breakdown voltage at 1 mA, 12.8 V stand-off voltage, 21.2 V clamping voltage at 18.9 A peak pulse current, and 300 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor signal lines and industrial I/O interfaces.
For engineers reviewing the TPSMP15AHM3/84A datasheet, TPSMP15AHM3/84A pinout, TPSMP15AHM3/84A application, or TPSMP15AHM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and uni-directional polarity with cathode band marking - critical for automotive-grade PCB layout and surge immunity validation.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for fast response time and low incremental surge resistance. Its unidirectional configuration enables robust forward-biased clamping during positive transients while maintaining tight reverse leakage (<1 μA at 12.8 V, 25 °C) and stable temperature coefficient (0.084 %/°C).
The device operates across -65 °C to +185 °C junction temperature range and delivers 300 W peak pulse power under standard 10/1000 μs waveform conditions when mounted on 5.0 mm × 5.0 mm copper pads. Its 2.5 V maximum forward voltage at 25 A supports reliable surge handling without excessive conduction loss.
Key Specifications

Pinout & Package
TPSMP15AHM3/84A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) surface-mount package. Polarity is marked by a cathode band on the case; the terminal with the band is the cathode (K), and the opposite end is the anode (A).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC (SMA) package; 15 V nominal VBR; 400 W PPPM; higher profile (2.29 mm) | Higher surge capacity but larger footprint and lower thermal performance in confined spaces | Prefer SMAJ15A where board area permits and >300 W pulse handling is required |
| TPSMA6.8A | Same DO-220AA package; lower VBR (6.45–7.14 V); 250 W PPPM; not AEC-Q101 qualified | Designed for consumer-grade 5 V systems, not automotive-qualified | Select TPSMA6.8A only for cost-sensitive non-automotive applications with lower voltage rails |
Compared with SMAJ15A and TPSMA6.8A, the TPSMP15AHM3/84A uniquely combines AEC-Q101 qualification, 1.0 mm height, and 300 W pulse rating in DO-220AA - making it optimal for space-constrained automotive signal protection where reliability and thermal margin are prioritized over raw power rating.

FAQ
What is the breakdown voltage range of the TPSMP15AHM3/84A?
The TPSMP15AHM3/84A has a guaranteed breakdown voltage (VBR) range of 14.3 V (minimum) to 15.8 V (maximum) measured at 1 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in automotive and industrial circuits where the TPSMP15AHM3/84A is deployed.
Is the TPSMP15AHM3/84A suitable for automotive applications?
Yes, the TPSMP15AHM3/84A is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C junction temperature. Its DO-220AA package, MSL Level 1 rating, and passivated anisotropic rectifier technology meet automotive reliability requirements - making the TPSMP15AHM3/84A appropriate for engine control, body electronics, and ADAS sensor protection.
What is the clamping voltage of the TPSMP15AHM3/84A at its rated peak pulse current?
The TPSMP15AHM3/84A clamps to a maximum of 21.2 V at 18.9 A peak pulse current (10/1000 μs waveform). This value is specified in the Vishay datasheet and directly determines the maximum voltage imposed on downstream circuitry during surge events - a critical parameter when selecting the TPSMP15AHM3/84A for protecting 12 V automotive systems.
Does the TPSMP15AHM3/84A have polarity marking, and how is it identified?
Yes, the TPSMP15AHM3/84A features a cathode band printed on the case to indicate polarity. The terminal adjacent to the band is the cathode (K), and the opposite end is the anode (A). This unidirectional configuration requires correct orientation during PCB placement - misalignment would prevent proper clamping function and render the TPSMP15AHM3/84A ineffective.
What packaging format is used for the TPSMP15AHM3/84A?
The TPSMP15AHM3/84A is supplied in 7-inch plastic tape and reel format with a base quantity of 3000 units per reel (package code 84A). The tape complies with EIA-481 standards and supports automated SMT placement. The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification - all verified for the TPSMP15AHM3/84A.
