Product details
Overview
TPSMA13AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 22.0 A peak pulse current (IPPM), 18.2 V maximum clamping voltage (VC) at IPPM, and 400 W peak pulse power (10/1000 µs). It is used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial control systems.
For engineers reviewing the TPSMA13AHM3_B/H datasheet, TPSMA13AHM3_B/H pinout, TPSMA13AHM3_B/H application, or TPSMA13AHM3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction temperature rating, low clamping ratio (VC/VBR ≈ 1.40), and halogen-free, RoHS-compliant construction with MSL Level 1 moisture sensitivity.
Technical Context
This TVS diode operates as a voltage-clamping protection device using passivated anisotropic rectifier technology. Its unidirectional structure enables forward conduction only during reverse overvoltage events, with fast response time (<1 ns) and low incremental surge resistance ensuring effective suppression of 10/1000 µs transients up to 400 W.
Designed for high-reliability environments, the TPSMA13AHM3_B/H supports continuous operation from –65 °C to +185 °C junction temperature and meets AEC-Q101 stress test requirements. Its SMA (DO-214AC) package provides robust thermal dissipation on PCBs with 5.0 mm × 5.0 mm copper pads and complies with J-STD-020 MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nominal) | 13.0 V - Ensures reliable triggering above normal operating voltage while maintaining margin against false clamping. |
| VWM | 11.1 V - Maximum continuous reverse working voltage before leakage exceeds 1 µA; defines safe operating range for 12 V systems. |
| VC @ IPPM | 18.2 V - Clamped voltage during 22.0 A transient; limits downstream component stress in automotive 12 V rail protection. |
| PPPM | 400 W - Peak pulse power handling per 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 surge immunity testing. |
| TJ max. | +185 °C - Enables use in under-hood automotive modules and high-temperature industrial enclosures without derating. |
| Polarity | Unidirectional - Provides reverse-biased clamping only; requires correct orientation relative to protected line polarity. |
| Qualification | AEC-Q101 qualified - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with matte tin-plated leads. Cathode indicated by color band; terminals are anode and cathode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during clamping | Connected to protected line (e.g., 12 V supply or signal trace); conducts during reverse overvoltage event. |

| Halogen-free, RoHS-compliant | Meets EU Directive 2011/65/EU and automotive material compliance standards (e.g., GMW3172, Ford WSS-M99P9999-A1). |
| Low clamping ratio (VC/VBR = 1.40) | Minimizes overvoltage overshoot during transient suppression, improving safety margin for 13.5 V-rated components. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Voltage clamping element placed between power input and ground, triggered within nanoseconds of overvoltage onset. Use Value: Limits peak voltage to ≤18.2 V during 22 A surges, preventing damage to downstream DC-DC converters and microcontrollers. | Use Scenario: Shielding analog output lines of pressure/temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional transient shunt on low-current signal paths (e.g., 4–20 mA loops), leveraging unidirectional configuration with proper biasing. Use Value: Maintains signal integrity by clamping ESD and switching noise to <18.2 V while adding <1 pF junction capacitance at 0 V bias. |
| Consumer Device USB Port Protection | Telecom Base Station DC Input Protection |
Use Scenario: Safeguarding USB VBUS lines in portable medical monitors against hot-plug induced transients and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBUS and GND, sized to handle 10/1000 µs surges up to 400 W without latch-up. Use Value: Achieves <1 ns response time and 11.1 V stand-off to avoid interference with 5 V USB regulation while surviving ±15 kV contact ESD (IEC 61000-4-2). | Use Scenario: Protecting -48 V DC input stages of telecom remote radio units from lightning-induced surges on outdoor power feeds. IC Role / Device Role / Timing Role: Primary clamping device in multi-stage protection circuit, coordinated with GDT and MOV for staged energy absorption. Use Value: Delivers precise 13.0 V breakdown and 18.2 V clamping to interface cleanly with secondary TVS arrays and ensure system-level IEC 61000-4-5 compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13AHE3_A/H | Same SMA package, 13 V VBR, but rated for 400 W with 10/1000 µs waveform and AEC-Q101 qualified; differs in marking code and tape/reel packaging. | Identical electrical specs and qualification; differs only in ordering suffix (HE3 vs HM3) and halogen content (HE3 not halogen-free). | Select SMAJ13AHE3_A/H if halogen-free requirement is not mandated; otherwise TPSMA13AHM3_B/H is preferred for strict automotive material compliance. |
| 1.5SMC13A | Higher power (1500 W), larger SMC (DO-214AB) package, same 13 V VBR; not AEC-Q101 qualified; higher VC (21.5 V). | Used where higher surge energy handling is required and board space allows larger footprint; unsuitable for space-constrained AEC-Q101 designs. | Choose 1.5SMC13A only when surge energy exceeds 400 W capability and AEC-Q101 is not required; TPSMA13AHM3_B/H remains optimal for compact, qualified automotive layouts. |
Compared with SMAJ13AHE3_A/H, TPSMA13AHM3_B/H adds halogen-free compliance without sacrificing performance; versus 1.5SMC13A, it trades surge capacity for smaller size and automotive qualification-making it the preferred choice for space-limited, production-grade automotive and industrial PCBs requiring full material traceability.

FAQ
What is the breakdown voltage tolerance for TPSMA13AHM3_B/H?
The TPSMA13AHM3_B/H has a specified breakdown voltage (VBR) range of 12.40 V (min) to 13.70 V (max) at 1.0 mA test current, with 13.0 V as the nominal value. This ±5% tolerance ensures consistent clamping behavior across production lots while allowing margin for thermal drift, which is characterized by a typical temperature coefficient of +0.072 %/°C.
Is TPSMA13AHM3_B/H suitable for bidirectional transient protection?
No, TPSMA13AHM3_B/H is unidirectional only, as explicitly stated in the Vishay datasheet. It functions as a reverse-biased clamp and does not suppress positive-going transients on grounded lines. For bidirectional protection, a dedicated bidirectional TVS such as SMBJ13CA or a back-to-back unidirectional pair would be required-not the TPSMA13AHM3_B/H itself.
Does TPSMA13AHM3_B/H meet AEC-Q101 requirements?
Yes, TPSMA13AHM3_B/H is AEC-Q101 qualified, as confirmed by its HM3 suffix and documentation in Vishay's 88405 datasheet. The HM3 variant is halogen-free, RoHS-compliant, and validated across all AEC-Q101 stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT).
What is the maximum clamping voltage of TPSMA13AHM3_B/H at its rated peak pulse current?
The maximum clamping voltage (VC) of TPSMA13AHM3_B/H is 18.2 V at its rated peak pulse current (IPPM) of 22.0 A, measured under the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage margining in protected circuits.
Can TPSMA13AHM3_B/H be used in a 24 V system?
TPSMA13AHM3_B/H is not recommended for direct use on 24 V systems due to its 11.1 V stand-off voltage (VWM) and 13.0 V nominal breakdown-both below typical 24 V rail operating ranges. Using it there risks premature conduction and thermal runaway. For 24 V applications, higher-voltage variants like TPSMA27AHM3_B/H (VWM = 23.1 V) are appropriate alternatives.
