Product details
Overview
T15B13AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for automotive-grade circuit protection. It delivers 1500 W peak pulse power (10/1000 μs), clamps at 18.5 V under 83.8 A surge current, and operates with 11.1 V stand-off voltage and 12.4–13.7 V breakdown range at 1 mA test current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning-induced surges.
For engineers reviewing the T15B13AHM3/H datasheet, T15B13AHM3/H pinout, T15B13AHM3/H application, or T15B13AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C junction temperature rating, SMB (DO-214AA) package compatibility, and verified clamping performance under standardized 10/1000 μs surge conditions.
Technical Context
The T15B13AHM3/H employs passivated anisotropic rectifier technology to achieve stable breakdown behavior and low leakage (<2 μA at 11.1 V, <10 μA at 150 °C). Its unidirectional architecture enables precise reverse-biased clamping without forward conduction during normal operation.
It meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow tolerance and supports high-reliability automotive environments via TJ = –65 °C to +185 °C operating range and IEC 61000-4-2 ±30 kV ESD immunity (contact/air discharge).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V at 1 mA - defines precise overvoltage triggering threshold for reliable clamping onset |
| VWM | 11.1 V - maximum continuous reverse working voltage before leakage exceeds 2 μA |
| VC @ IPPM | 18.5 V at 83.8 A - clamped voltage during full 1500 W surge, limiting downstream stress |
| PPPM | 1500 W (10/1000 μs) - peak transient energy absorption capability for automotive load-dump and ISO 7637-2 compliance |
| TJ max | +185 °C - enables placement near hot components (e.g., powertrain ECUs) without derating |
| ESD Rating | ±30 kV per IEC 61000-4-2 - protects sensor interfaces and CAN/LIN bus nodes from static discharge |
| AEC-Q101 | Qualified - certified for automotive electronic systems per stress-test requirements including HTGB, HTRB, and TCT |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-H | Same SMB package, 13 V VBR, but rated at 600 W PPPM (10/1000 μs); no AEC-Q101 qualification | Targeted at industrial/commercial designs where automotive qualification is not required | Select when cost sensitivity outweighs automotive reliability requirements and surge energy is ≤600 W |
| 1.5SMC13A | Same 13 V VBR family, 1500 W rating, but in larger SMC (DO-214AB) package; AEC-Q101 qualified | Used where PCB space allows larger footprint and higher thermal mass improves sustained surge handling | Choose when board layout permits SMC and enhanced thermal dissipation is needed for repetitive surge events |
Compared with SMBJ13A-H and 1.5SMC13A, the T15B13AHM3/H uniquely combines AEC-Q101 qualification, 1500 W capability, and SMB footprint-making it optimal for space-constrained automotive modules requiring full ISO 7637-2 compliance without package redesign.

FAQ
What is the clamping voltage of the T15B13AHM3/H under maximum surge current?
The T15B13AHM3/H exhibits a maximum clamping voltage (VC) of 18.5 V when subjected to its rated peak pulse current (IPPM) of 83.8 A using the standard 10/1000 μs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 98360) and ensures downstream components remain within safe voltage limits during transient events. The T15B13AHM3/H maintains this clamping performance across its full operating temperature range up to +185 °C.
Is the T15B13AHM3/H suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the T15B13AHM3/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Revision: 19-Jan-2024, Document Number: 98360). It passes all required stress tests-including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT)-making it approved for use in automotive powertrain, body electronics, and ADAS systems. The T15B13AHM3/H also meets MSL Level 1 and IEC 61000-4-2 ±30 kV ESD requirements.
What does the "HM3" suffix indicate in T15B13AHM3/H?
"HM3" denotes Vishay's halogen-free, RoHS-compliant, and AEC-Q101-qualified construction. It specifies matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, plus JESD 201 Class 2 whisker resistance. The "/H" suffix indicates packaging in 7″ plastic tape and reel (750 units per reel). This full designation confirms the T15B13AHM3/H meets stringent automotive material and process requirements beyond baseline commercial TVS diodes.
How does the T15B13AHM3/H compare to standard SMBJ-series TVS diodes?
The T15B13AHM3/H provides identical 13 V nominal breakdown voltage as SMBJ13A but delivers 1500 W peak pulse power (vs. 600 W for SMBJ13A) and carries AEC-Q101 qualification-neither of which applies to standard SMBJ parts. Its passivated anisotropic rectifier structure also yields tighter VBR tolerance (12.4–13.7 V) and lower leakage at elevated temperatures. These distinctions make the T15B13AHM3/H appropriate where the SMBJ13A would thermally saturate or fail qualification audits.
What is the maximum operating junction temperature for the T15B13AHM3/H?
The T15B13AHM3/H has a maximum rated junction temperature (TJ) of +185 °C, validated per the Vishay datasheet (Document Number: 98360). This rating enables reliable operation in under-hood automotive environments and near high-power components without thermal derating. The device's thermal performance is supported by its SMB (DO-214AA) package with optimized thermal resistance and passivated die structure, ensuring stable VBR and leakage behavior up to TJ = 185 °C.
