Product details
Overview
T15B13AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for automotive-grade overvoltage protection of sensitive electronics. It delivers 1500 W peak pulse power (10/1000 μs), clamps at 18.5 V under 83.8 A surge current, and operates up to 185 °C junction temperature-ideal for protecting MOSFETs and sensor signal lines in engine control units.
For engineers reviewing the T15B13AHM3/I datasheet, T15B13AHM3/I pinout, T15B13AHM3/I application, or T15B13AHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, SMB (DO-214AA) package, 13.0 V nominal breakdown voltage, 11.1 V stand-off voltage, and 2.0 μA max reverse leakage at VWM-critical for low-power automotive sensor interfaces.
Technical Context
The T15B13AHM3/I employs passivated anisotropic rectifier technology to achieve stable clamping performance across temperature extremes. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow compatibility up to 260 °C peak, meeting stringent automotive reliability requirements.
As a unidirectional TVS diode, it conducts only during positive transients relative to cathode polarity (marked by color band). It meets IEC 61000-4-2 ESD immunity at ±30 kV (contact/air discharge), and its 0.072 %/°C VBR temperature coefficient enables predictable voltage threshold behavior from -65 °C to +185 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise breakdown onset for reliable overvoltage triggering |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 2.0 μA |
| IPPM | 83.8 A - peak surge current capability with 10/1000 μs waveform, enabling robust lightning/inductive spike suppression |
| VC @ IPPM | 18.5 V - clamping voltage limiting protected circuit stress during full-rated surge |
| PPPM | 1500 W - peak pulse power dissipation capacity under standardized transient conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same SMB package, 13 V VBR, but rated for 600 W PPPM and not AEC-Q101 qualified | Limited to industrial/commercial use; lacks automotive reliability validation and high-temp stability | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin |
| SMCJ13A | Higher 1500 W rating in larger SMC (DO-214AB) package; same VBR and VC, but 2.3 g unit weight vs. 0.107 g | Requires PCB area increase (~30% larger footprint); suitable where space permits and higher thermal mass is beneficial | Select when enhanced thermal dissipation is needed and layout allows SMC footprint |
Compared with SMBJ13A and SMCJ13A, the T15B13AHM3/I uniquely combines AEC-Q101 qualification, 185 °C operation, and 1500 W capability in the compact SMB outline-making it the only choice for space-constrained, high-reliability automotive signal and power line protection.

FAQ
What is the maximum junction temperature rating for the T15B13AHM3/I?
The T15B13AHM3/I has a maximum junction temperature (TJ) rating of +185 °C, verified per AEC-Q101 stress testing. This enables reliable operation in under-hood automotive locations where ambient temperatures exceed 125 °C. The T15B13AHM3/I maintains specified clamping and leakage performance up to this limit, with derating curves provided in the official Vishay datasheet (Document Number: 98360).
Is the T15B13AHM3/I compatible with lead-free reflow soldering processes?
Yes, the T15B13AHM3/I is fully compatible with lead-free reflow soldering. It meets MSL Level 1 per J-STD-020 and supports a maximum peak reflow temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the HM3 suffix confirms qualification to JESD 201 Class 2 whisker resistance-ensuring robust solder joint integrity in high-volume automotive manufacturing.
Does the T15B13AHM3/I meet automotive qualification standards?
Yes, the T15B13AHM3/I is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet (Revision: 19-Jan-2024, Document Number: 98360). This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the clamping voltage of the T15B13AHM3/I at its rated peak pulse current?
The T15B13AHM3/I exhibits a maximum clamping voltage (VC) of 18.5 V at its rated peak pulse current (IPPM) of 83.8 A, measured using the standard 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and ensures protected circuits remain within safe voltage limits during surge events. The T15B13AHM3/I datasheet specifies this parameter in the Electrical Characteristics table on page 2.
How does the T15B13AHM3/I differ from the T15B12AHM3/I in terms of electrical parameters?
The T15B13AHM3/I has a higher nominal breakdown voltage (13.0 V vs. 12.0 V), stand-off voltage (11.1 V vs. 10.2 V), and clamping voltage (18.5 V vs. 17.0 V) than the T15B12AHM3/I. Both share identical package, power rating (1500 W), and AEC-Q101 qualification. The T15B13AHM3/I is selected when system operating voltage margins require tighter VWM headroom above 12 V nominal rails.
