Product details
Overview
TPSMP15AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the eSMP® Series, designed for high-reliability automotive and industrial overvoltage protection. It features a 14.3 V to 15.8 V breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 400 W peak pulse power (PPPM), 18.9 A peak pulse current (IPPM), and 21.2 V clamping voltage (VC) at IPPM, housed in an SMP (DO-220AA) package with 1.0 mm profile.
For engineers reviewing the TPSMP15AHM3_A/H datasheet, TPSMP15AHM3_A/H pinout, TPSMP15AHM3_A/H application, or TPSMP15AHM3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, low incremental surge resistance, fast response time, and suitability for protecting sensor signal lines and drive transistors in harsh environments.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-power-density transient suppression. Its unidirectional polarity enables precise reverse-biased clamping during voltage surges, with a maximum clamping voltage of 21.2 V at 18.9 A (10/1000 μs waveform) and a low 0.084 %/°C temperature coefficient of VBR.
Rated for operation from −65 °C to +185 °C, it meets MSL Level 1 per J-STD-020 and supports automated SMT placement. The device delivers 2.5 W steady-state power dissipation at 75 °C on infinite heatsink and withstands 40 A non-repetitive forward surge current (10 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 14.3 V / 15.8 V - defines reliable turn-on threshold under surge conditions |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 1 μA |
| VC @ IPPM | 21.2 V - clamped voltage seen by protected circuit during 18.9 A transient |
| PPPM | 400 W - peak transient energy absorption capability (10/1000 μs waveform) |

Applications
| Automotive Sensor Protection | Industrial Motor Drive Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed between signal line and ground. Use Value: Limits transient voltage to ≤21.2 V during 18.9 A surges, preserving signal integrity and preventing latch-up in downstream ASICs. | Use Scenario: Safeguarding gate drivers and microcontroller I/O pins connected to motor feedback circuits (e.g., hall-effect sensors, encoder lines). IC Role / Device Role / Timing Role: Standoff-clamping protector on low-voltage digital/analog interface lines subject to inductive kickback. Use Value: Withstands 40 A surge current and operates up to +185 °C, enabling robust protection in enclosed motor control enclosures. |

Use Scenario: Secondary-side surge suppression on 12 V DC output rails of wall adapters exposed to ESD and conducted noise. IC Role / Device Role / Timing Role: Fast-response clamping diode placed adjacent to connector or LDO input. Use Value: 21.2 V clamping ensures downstream regulators remain within absolute maximum ratings during 1 kV EFT bursts. | Use Scenario: Protecting RS-485/RS-232 control lines in outdoor telecom cabinets subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Point-of-entry TVS on differential data lines referenced to local ground plane. Use Value: 400 W PPPM and low incremental surge resistance minimize let-through energy to <100 mJ, reducing risk of transceiver damage. |
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 | Higher VC = 24.4 V at same IPPM; lower PPPM = 400 W but larger SMA package (2.5 mm height) | Less suitable for ultra-low-profile automotive modules due to 2.5× height increase | Choose SMAJ15A only if board height budget allows and legacy SMA footprint is fixed |
| TPSMA6.8A | Lower VBR (6.45–7.14 V); same SMP package but rated for 300 W PPPM and 23.8 V VC | Designed for 5 V rail protection, not compatible for 12 V systems requiring ≥14.3 V VBR | Select TPSMA6.8A only for sub-8 V signal line protection; TPSMP15AHM3_A/H is required for 12 V automotive interfaces |
Compared with SMAJ15A and TPSMA6.8A, TPSMP15AHM3_A/H uniquely combines AEC-Q101 qualification, 1.0 mm profile, and precise 14.3–15.8 V VBR in DO-220AA - making it the only option validated for space-constrained, high-temperature automotive signal line protection.

FAQ
What is the clamping voltage of the TPSMP15AHM3_A/H at its rated peak pulse current?
The TPSMP15AHM3_A/H has a maximum clamping voltage (VC) of 21.2 V when subjected to its rated peak pulse current of 18.9 A using the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected ICs experience no more than 21.2 V during transient events, critical for safeguarding 12 V system interfaces.
Is the TPSMP15AHM3_A/H qualified for automotive applications?
Yes, the TPSMP15AHM3_A/H is AEC-Q101 qualified and rated for operation from −65 °C to +185 °C. Its construction-halogen-free molding compound, matte tin-plated leads, and MSL Level 1 reflow compatibility-meets automotive manufacturing and reliability requirements, making TPSMP15AHM3_A/H suitable for engine control, ADAS, and body electronics.
What package type does the TPSMP15AHM3_A/H use, and what are its key mechanical features?
The TPSMP15AHM3_A/H uses the SMP (DO-220AA) package: a surface-mount, low-profile case measuring 3.61 mm × 2.18 mm × 1.0 mm. Key features include a cathode identification band, UL 94 V-0 compliant molding compound, and terminals qualified for J-STD-002 solderability and JESD 201 Class 2 whisker resistance-ensuring robust assembly and field reliability.
How does the TPSMP15AHM3_A/H compare to the TPSMP12A in terms of breakdown voltage and application scope?
The TPSMP15AHM3_A/H has a VBR range of 14.3–15.8 V versus 11.4–12.6 V for TPSMP12A, making TPSMP15AHM3_A/H appropriate for 12 V nominal systems where higher standoff is needed. Its 400 W PPPM also exceeds TPSMP12A's 300 W, allowing TPSMP15AHM3_A/H to handle larger transients in demanding automotive and industrial environments.
What is the maximum reverse leakage current of the TPSMP15AHM3_A/H at its stand-off voltage?
At its 12.8 V stand-off voltage (VWM) and ambient temperature of 25 °C, the TPSMP15AHM3_A/H exhibits a maximum reverse leakage current (IR) of 1.0 μA. At elevated junction temperature (TJ = 150 °C), leakage increases to 5.0 μA-still well within safe limits for low-power sensor and communication line protection.
