Product details
Overview
TPSMP13AHM3_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 surge protection. It features a 12.4 V to 13.7 V breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 400 W peak pulse power (PPPM), 185 °C maximum junction temperature, and SMP (DO-220AA) package with 1.0 mm typical height - used to protect sensor signal lines and drive transistors against ESD and lightning-induced transients.
For engineers reviewing the TPSMP13AHM3_A/H datasheet, TPSMP13AHM3_A/H pinout, TPSMP13AHM3_A/H application, or TPSMP13AHM3_A/H equivalent, key selection criteria include clamping voltage (18.2 V at IPPM), low incremental surge resistance, AEC-Q101 qualification, unidirectional polarity, and MSL Level 1 reflow compatibility.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for junction stability under repetitive surge stress. Its unidirectional architecture enables precise reverse-biased clamping during overvoltage events, with fast response time and low dynamic impedance ensuring effective suppression of 10/1000 µs transients up to 22.0 A peak pulse current.
The device operates across -65 °C to +185 °C and is rated for 2.5 W steady-state power dissipation on infinite heatsink at 75 °C. Its SMP (DO-220AA) package supports automated placement and meets UL 94 V-0 flammability rating, JESD 201 Class 2 whisker resistance, and halogen-free, RoHS-compliant construction.

Pinout & Package
TPSMP13AHM3_A/H uses a two-terminal SMP (DO-220AA) package: anode and cathode are marked by a color band denoting the cathode end. The device has no internal leads or multi-pin configuration - terminals are matte tin-plated for solderability per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to ground or low-impedance return path in unidirectional TVS configurations |
| Cathode | Clamping node | Connected to protected line; conducts when reverse voltage exceeds VWM, clamping to ≤18.2 V |
Key Features

Use Scenario: Shielding USB-C PD communication lines and auxiliary power rails in compact wall adapters subjected to ESD and conducted EMI. IC Role / Device Role / Timing Role: Low-capacitance TVS mounted directly at connector entry point to shunt fast transients before IC-level protection. Use Value: 1.0 mm height allows integration into ultra-thin adapter PCBs; halogen-free, RoHS-compliant construction meets IEC 62368-1 safety requirements. | Use Scenario: Protecting analog front-end inputs (e.g., ECG, EEG amplifiers) from electrostatic discharge during patient contact or probe handling. IC Role / Device Role / Timing Role: High-reliability TVS placed at signal conditioning stage input to prevent latch-up or offset shift in precision op-amps. Use Value: AEC-Q101 qualification ensures long-term parameter stability and low IR drift - critical for FDA-cleared diagnostic accuracy compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Higher VC (21.5 V), lower PPPM (400 W same but derated faster above 25 °C), SMA package (2.5 mm height) | Less suitable for space-constrained automotive modules; requires larger PCB footprint | Select if legacy SMA footprint compatibility is required and height budget allows ≥2.5 mm |
| TPSMA6.8A | Lower VBR (6.45–7.14 V), same package, lower PPPM (250 W), not AEC-Q101 qualified | Not validated for automotive use; limited to consumer/industrial applications with less stringent reliability demands | Choose only for cost-sensitive non-automotive designs where 11.1 V VWM and AEC-Q101 are unnecessary |
Compared with SMAJ13A and TPSMA6.8A, TPSMP13AHM3_A/H delivers superior height efficiency (1.0 mm vs. 2.5 mm), guaranteed AEC-Q101 qualification, and tighter VBR tolerance - making it the preferred choice for next-generation automotive electronics requiring miniaturization and certified reliability.

FAQ
What is the clamping voltage of TPSMP13AHM3_A/H at its rated peak pulse current?
The clamping voltage (VC) of TPSMP13AHM3_A/H is 18.2 V when subjected to its maximum peak pulse current (IPPM) of 22.0 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain below critical voltage thresholds during surge events. TPSMP13AHM3_A/H maintains this performance across its full operating temperature range.
Is TPSMP13AHM3_A/H qualified for automotive applications?
Yes, TPSMP13AHM3_A/H is AEC-Q101 qualified and rated for operation from -65 °C to +185 °C, making it suitable for under-hood and transmission-control applications. Its construction meets JESD 201 Class 2 whisker resistance, MSL Level 1 reflow, and halogen-free RoHS compliance - all verified per Vishay's qualification report for the TPSMP family. TPSMP13AHM3_A/H is explicitly listed in the automotive-grade ordering table.
What does the "HM3_A/H" suffix indicate in TPSMP13AHM3_A/H?
The "HM3" denotes the halogen-free, RoHS-compliant, AEC-Q101-qualified SMP (DO-220AA) package variant; "A" is the revision code; "/H" specifies packaging in 7-inch plastic tape and reel with 3000 units per reel. This suffix confirms TPSMP13AHM3_A/H meets material and assembly standards required for automotive production, including J-STD-002 solderability and UL 94 V-0 flammability.
How does TPSMP13AHM3_A/H compare to bidirectional TVS diodes in signal line protection?
TPSMP13AHM3_A/H is unidirectional and optimized for DC-biased lines where only reverse-polarity transients occur - offering lower leakage (<1 μA at 11.1 V) and tighter VBR tolerance than equivalent bidirectional devices. Unlike bidirectional TVS diodes, TPSMP13AHM3_A/H avoids forward conduction during normal operation, preserving signal fidelity in analog and digital interfaces where bias stability is critical.
What is the maximum steady-state power dissipation for TPSMP13AHM3_A/H?
The maximum steady-state power dissipation (PD) for TPSMP13AHM3_A/H is 2.5 W when mounted on an infinite heatsink at 75 °C ambient. Derating follows the curve in Figure 6 of the datasheet, dropping to ~1.25 W at 125 °C ambient. This rating applies only to continuous DC or low-duty-cycle conditions - transient suppression relies on the 400 W PPPM rating, not PD. TPSMP13AHM3_A/H must be applied within these thermal limits to ensure long-term reliability.
