Product details
Overview
TPSMA13AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching and lightning-induced transients on power rails and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 22.0 A peak pulse current (IPPM), 18.2 V maximum clamping voltage (VC) at IPPM, 400 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive sensor protection and industrial power supply input stages.
For engineers reviewing the TPSMA13AHE3_B/I datasheet, TPSMA13AHE3_B/I pinout, TPSMA13AHE3_B/I application, or TPSMA13AHE3_B/I equivalent, key selection criteria include unidirectional polarity, SMA (DO-214AC) package compatibility, AEC-Q101 qualification status, TJ = 185 °C thermal rating, and verified clamping performance under 10/1000 µs surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping across temperature. Its unidirectional architecture enables forward-biased conduction during overvoltage events while maintaining low leakage (<1.0 µA at VWM = 11.1 V) and fast response time.
The device is rated for 40 A non-repetitive peak forward surge current (IFSM) and exhibits 0.072 %/°C temperature coefficient of VBR, enabling predictable voltage threshold shift from −65 °C to +185 °C. It meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 V / 13.0 V / 13.7 V - defines precise clamping onset threshold at 1.0 mA test current |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1.0 µA |
| VC @ IPPM | 18.2 V - clamped voltage during 22.0 A 10/1000 µs surge, limiting downstream IC stress |
| PPPM | 400 W - peak pulse power handling capability under standardized transient waveform |
| TJ max. | +185 °C - enables operation in high-temperature engine bay or industrial power converter environments |
| IFSM | 40 A - withstands 8.3 ms half-sine surge without failure, critical for motor drive protection |
| αT | 0.072 %/°C - quantifies VBR drift with temperature, supporting accurate thermal design margining |
Pinout & Package
Package: SMA (DO-214AC) - surface-mount plastic case with matte tin-plated leads, UL 94 V-0 rated molding compound, and cathode band marking. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per JEDEC standard layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink node | Connected to protected line; conducts surge current to ground when VAK > VBR |
| Anode | Reference/ground return path | Typically tied to system ground or low-impedance return plane to complete clamping loop |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A (Bourns) | Same VBR range (12.4–13.7 V), but SMB package (DO-214AA); 600 W PPPM; higher VC = 21.5 V | Larger footprint; better suited for higher-energy surges where board space allows | Select when higher pulse power margin is required and PCB layout accommodates larger SMB outline |
| 1.5SMC13A (ON Semiconductor) | Same VBR and VC; SMC (DO-214AB) package; 1500 W PPPM; 1.5 kW rating reflects different test condition (1.5 kW vs. 400 W at 10/1000 µs) | Higher energy handling but larger size and higher cost; not AEC-Q101 qualified | Choose for non-automotive industrial systems needing greater single-pulse robustness without qualification constraints |
Compared with SMBJ13A and 1.5SMC13A, the TPSMA13AHE3_B/I offers optimal balance of AEC-Q101 compliance, compact SMA footprint, and validated 400 W clamping performance - making it preferred for space-constrained automotive and industrial designs requiring production-grade reliability.

FAQ
What is the breakdown voltage tolerance for TPSMA13AHE3_B/I?
The TPSMA13AHE3_B/I has a guaranteed breakdown voltage range of 12.4 V (minimum) to 13.7 V (maximum) at 1.0 mA test current, with 13.0 V nominal value. This ±5% tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage protection design margins in 12 V systems.
Is TPSMA13AHE3_B/I RoHS-compliant and halogen-free?
Yes, the TPSMA13AHE3_B/I carries the HE3 suffix, indicating RoHS-compliance and AEC-Q101 qualification. It is not halogen-free; for halogen-free compliance, the HM3 suffix variant (e.g., TPSMA13AHM3_B/I) must be selected. Both meet JESD201 Class 2 whisker resistance and J-STD-002 solderability standards.
What is the maximum clamping voltage of TPSMA13AHE3_B/I under surge conditions?
The TPSMA13AHE3_B/I clamps to a maximum of 18.2 V when subjected to its rated 22.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This VC value is measured at TA = 25 °C on specified PCB pad layout and defines the upper voltage limit imposed on protected circuitry during transient events.
Can TPSMA13AHE3_B/I be used in bidirectional configurations?
No, TPSMA13AHE3_B/I is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts surge current only from cathode to anode during reverse overvoltage events. For bidirectional protection, a dedicated bidirectional TVS (e.g., TPSMA13CA) or back-to-back unidirectional configuration would be required - neither of which applies to this part number.
What is the thermal resistance junction-to-ambient (RθJA) for TPSMA13AHE3_B/I?
Vishay does not publish RθJA for TPSMA13AHE3_B/I in the provided datasheet. Thermal performance is characterized via derating curves (Fig. 2) showing pulse power vs. initial junction temperature. Designers must use the 185 °C maximum junction temperature rating and apply appropriate PCB copper area (0.2" × 0.2" pads per terminal) to ensure safe operation under sustained power dissipation.
