Product details
Overview
TPSMB13AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping inductive switching transients and lightning-induced surges on power and signal lines. It features 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 18.2 V maximum clamping voltage at 33 A peak pulse current, 600 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature - enabling robust protection in automotive engine control units and industrial sensor interfaces.
For engineers reviewing the TPSMB13AHM3_A/I datasheet, TPSMB13AHM3_A/I pinout, TPSMB13AHM3_A/I application, or TPSMB13AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, halogen-free RoHS compliance, MSL Level 1 rating, and verified 185 °C thermal capability for under-hood automotive deployments.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, triggering into avalanche conduction when reverse voltage exceeds its 12.4–13.7 V breakdown range. Its low incremental surge resistance and fast response time ensure effective suppression of sub-microsecond transients without latch-up or thermal runaway.
The device uses passivated anisotropic rectifier technology to achieve stable performance across -65 °C to +185 °C operating range, with 0.072 %/°C temperature coefficient of VBR and <2 µA reverse leakage at 11.1 V (TA = 25 °C). It is rated for 75 A non-repetitive forward surge current (8.3 ms half-sine) and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise avalanche onset threshold for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 2 µA |
| VC @ IPPM | 18.2 V at 33 A - clamped voltage during 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W (10/1000 µs waveform) - peak surge energy handling capacity under standardized test conditions |
| TJ max. | +185 °C - enables operation in high-temperature environments such as automotive powertrain modules |
| Polarity | Unidirectional - protects against positive-going transients only; cathode band denotes terminal orientation |
| Package | SMB (DO-214AA) - industry-standard surface-mount outline with 0.220" x 0.130" footprint and MSL Level 1 reflow compatibility |
Pinout & Package
SMB (DO-214AA) package with two terminals: cathode (marked by color band) and anode. Matte tin-plated leads meet J-STD-002 solderability and JESD22-B102 mechanical reliability standards. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts avalanche current to ground during overvoltage events |
| Anode | Reference/return path | Typically tied to system ground or low-impedance return plane to complete clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standard |
| Halogen-free & RoHS-compliant | Meets EU Directive 2011/65/EU and IPC-1752A material declaration requirements |
| MSL Level 1 (260 °C peak) | Enables single-reflow assembly without moisture sensitivity concerns or baking preconditioning |
| 185 °C junction rating | Supports placement near heat sources (e.g., power MOSFETs, ignition coils) without derating |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during fast transients, reducing risk of gate oxide damage in protected FETs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VBR range (12.4–13.7 V), but lower PPPM = 400 W and VC = 21.2 V at 19.3 A; SMA package (smaller thermal mass) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or high-current inductive switching | Select TPSMB13AHM3_A/I when 600 W surge handling and 185 °C operation are required. |
| TPSMB13AHE3_A/I | Identical electrical specs and SMB package; differs only in termination - HE3 suffix indicates standard RoHS (non-halogen-free) construction | No functional difference; HE3 variant lacks halogen-free certification required for some automotive OEMs | Choose TPSMB13AHM3_A/I where halogen-free compliance and AEC-Q101 qualification are mandatory. |
Compared with SMAJ13A, TPSMB13AHM3_A/I delivers 50 % higher surge power handling and tighter clamping, while versus TPSMB13AHE3_A/I it adds halogen-free materials and identical AEC-Q101 validation - making it the preferred choice for Tier 1 automotive supply chains requiring full material compliance.

FAQ
What is the maximum clamping voltage of the TPSMB13AHM3_A/I under peak pulse conditions?
The TPSMB13AHM3_A/I exhibits a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current of 33 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and ensures downstream components with 20 V absolute maximum ratings remain within safe operating limits during transient events.
Is the TPSMB13AHM3_A/I qualified for automotive applications?
Yes, the TPSMB13AHM3_A/I is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade reliability. It has passed stress tests including high-temperature reverse bias, temperature cycling, and unbiased highly accelerated stress testing - confirming suitability for engine control, body electronics, and ADAS subsystems.
What does the "HM3" suffix signify in TPSMB13AHM3_A/I?
The "HM3" suffix in TPSMB13AHM3_A/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. It distinguishes this variant from the HE3 version (RoHS-compliant but not halogen-free) and confirms compliance with IPC-1752A material declarations and JEDEC J-STD-020 MSL Level 1 reflow specifications.
Can TPSMB13AHM3_A/I be used in bidirectional protection circuits?
No, the TPSMB13AHM3_A/I is unidirectional only, as confirmed in the Vishay datasheet. It protects against positive-going transients on the cathode side relative to anode. For bidirectional protection, a pair of TPSMB13AHM3_A/I devices in series-opposed configuration or a dedicated bidirectional TVS (e.g., TPSMB13CA) must be used.
What is the thermal derating behavior of TPSMB13AHM3_A/I above 25 °C ambient?
The TPSMB13AHM3_A/I follows linear derating above TA = 25 °C per Figure 2 in the datasheet: peak pulse power decreases by approximately 0.6 %/°C, reaching ~50 % of rated 600 W at 125 °C ambient. This allows continued operation up to TJ = 185 °C when PCB layout provides adequate copper thermal relief.
