Product details
Overview
TPSMC13AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 18.2 V clamping voltage at 82.4 A peak surge current, and operates up to +185 °C junction temperature.
For engineers reviewing the TPSMC13AHE3_B/I datasheet, TPSMC13AHE3_B/I pinout, TPSMC13AHE3_B/I application, or TPSMC13AHE3_B/I equivalent, this page delivers verified electrical parameters, thermal limits, automotive qualification status (AEC-Q101), RoHS compliance, and real-world use context for ESD/surge protection in signal lines, power rails, and sensor interfaces.
Technical Context
The TPSMC13AHE3_B/I implements passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under repeated transients. Its unidirectional polarity enables forward-biased operation during positive surges while blocking reverse leakage up to 2.0 µA at VWM.
Rated for TJ = –65 °C to +185 °C, it supports high-temperature environments including under-hood automotive systems and industrial motor controls. The device meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing, confirming robust solderability and long-term reliability in reflow assembly.

| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN bus transceivers and analog sensor inputs (e.g., oxygen, pressure) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp positive transients only. Use Value: Maintains signal integrity below 18.2 V clamping threshold while surviving 1500 W surges per AEC-Q101 stress profiles. | Use Scenario: Shielding digital input modules from relay coil flyback and motor drive noise in factory automation cabinets. IC Role / Device Role / Timing Role: Standoff-rated TVS on 24 V DC input lines, absorbing repetitive 100–200 A inductive spikes. Use Value: 11.1 V VWM ensures no leakage interference on logic thresholds; 185 °C rating supports sealed enclosure operation. |
| Telecom Power Rail Protection | Consumer USB Port ESD Guard |
Use Scenario: Safeguarding 12 V bias rails feeding RF front-end ICs in base station power supplies against AC line transients. IC Role / Device Role / Timing Role: Primary-level TVS on DC input, coordinated with downstream polymer PTCs and ceramic capacitors. Use Value: 1500 W PPPM handles IEC 61000-4-5 Level 4 surges; low capacitance avoids signal distortion on high-frequency rails. | Use Scenario: Adding secondary-level surge immunity to USB 2.0 data lines (D+/D−) and VBUS in smart home hubs. IC Role / Device Role / Timing Role: Unidirectional TVS on VBUS line to absorb hot-plug inrush and contact ESD events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13AHE3_A/H | Lower PPPM (600 W), SMB (DO-214AA) package, same VBR/VWM tolerance | Not rated for AEC-Q101; limited to consumer/industrial use below 150 °C | Select when board space is constrained and surge energy requirements are ≤600 W |
| TPSMC13AHM3_B/I | Identical electrical specs; halogen-free molding compound, same AEC-Q101 qualification | No functional difference; used where halogen-free compliance is mandated (e.g., EU medical devices) | Choose for RoHS + halogen-free regulatory alignment without performance trade-offs |
Compared with SMBJ13AHE3_A/H and TPSMC13AHM3_B/I, the TPSMC13AHE3_B/I offers higher surge robustness (1500 W vs. 600 W) and automotive qualification in the larger SMC footprint-making it optimal for mission-critical 12 V systems where layout area permits and reliability is non-negotiable.

FAQ
What is the maximum clamping voltage of the TPSMC13AHE3_B/I under peak surge conditions?
The TPSMC13AHE3_B/I has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 82.4 A using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on the protected circuit during transient events. Engineers must verify that downstream components tolerate this clamped level under worst-case surge scenarios.
Is the TPSMC13AHE3_B/I qualified for automotive applications?
Yes, the TPSMC13AHE3_B/I is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified variants. This qualification covers stress tests including temperature cycling, humidity, mechanical shock, and high-temperature operating life-making the TPSMC13AHE3_B/I suitable for under-hood and cabin electronics in passenger vehicles and commercial fleets.
What does the "B/I" suffix mean in TPSMC13AHE3_B/I?
The "B/I" suffix in TPSMC13AHE3_B/I indicates two attributes: "B" is the revision code denoting the specific manufacturing revision per Vishay's internal documentation, and "I" specifies the packaging format-13-inch diameter plastic tape and reel with a base quantity of 3500 units. This differs from "H"-suffixed versions, which use 7-inch reels with 850-unit quantities.
Can the TPSMC13AHE3_B/I be used in bidirectional protection circuits?
No, the TPSMC13AHE3_B/I is unidirectional only, as explicitly stated in Vishay's datasheet. It conducts current in the forward direction (anode-to-cathode) during positive transients and blocks reverse current up to VWM. For bidirectional protection-such as AC line or differential signal applications-a dedicated bidirectional TVS like the SMAJ13CA or TPSMC13CA must be selected instead.
What is the thermal derating behavior of the TPSMC13AHE3_B/I above 25 °C ambient?
The TPSMC13AHE3_B/I follows Vishay's standard derating curve (Fig. 2 in datasheet 88407): peak pulse power decreases linearly from 100% at 25 °C to ~50% at 125 °C and ~25% at 175 °C. This reflects junction temperature rise limiting safe surge energy absorption. Designers must apply this derating when estimating survivability in high-ambient environments such as engine compartments or enclosed industrial enclosures.
