Product details
Overview
TPSMP13AHE3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade circuit protection. It features a breakdown voltage of 12.4 V to 13.7 V at 1 mA, clamps up to 18.2 V at 22.0 A peak pulse current, and delivers 400 W peak pulse power with 1.0 mm profile height.
For engineers reviewing the TPSMP13AHE3/85A datasheet, TPSMP13AHE3/85A pinout, TPSMP13AHE3/85A application, or TPSMP13AHE3/85A equivalent, this device serves as a high-reliability, AEC-Q101 qualified solution for protecting sensitive ICs and signal lines against ESD and surge transients in space-constrained automotive and industrial PCB layouts.
Technical Context
The TPSMP13AHE3/85A employs Vishay's patented PAR oxide-passivated chip construction, enabling low incremental surge resistance and excellent clamping performance under 10/1000 µs surge waveforms. Its unidirectional configuration supports DC-biased signal line protection with defined cathode polarity indicated by a color band.
Rated for operation from −65 °C to +185 °C junction temperature, it meets MSL Level 1 per J-STD-020 and is RoHS-compliant with matte tin-plated leads solderable per J-STD-002. The device is optimized for automated placement on FR-4 PCBs using Vishay's recommended 5.0 × 5.0 mm copper pads per terminal.

Applications
| Automotive Sensor Protection | Industrial I/O Interface Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) in engine bay modules exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role: Unidirectional TVS placed between signal line and ground to clamp transients before reaching sensitive input stages. Use Value: Clamps to 18.2 V at 22 A while maintaining 11.1 V standoff, ensuring signal integrity and preventing latch-up in 12 V automotive systems. |
Use Scenario: Safeguarding RS-485/RS-232 communication ports on PLC I/O cards subjected to field-induced surges and ESD events. IC Role / Device Role: Primary surge suppression element on differential data lines, coordinated with common-mode chokes. Use Value: Delivers 400 W peak pulse power handling with fast response time, meeting IEC 61000-4-5 Level 3 requirements without derating. |
| Consumer Power Adapter Input Protection | Automotive Body Control Module (BCM) |
Use Scenario: Secondary-side transient suppression on 5–12 V DC output rails of wall adapters and USB PD chargers. IC Role / Device Role: Standoff-rated TVS across output-to-ground to absorb coupling transients from primary-side switching noise or cable discharge. Use Value: Low leakage (<1 µA at 11.1 V) prevents standby power loss; 185 °C max junction temperature supports enclosed thermal environments. |
Use Scenario: Protecting microcontroller GPIOs and LED driver inputs in BCMs controlling lighting, door locks, and HVAC actuators. IC Role / Device Role: Point-of-load TVS on each protected signal path, leveraging DO-220AA's small footprint for multi-channel integration. Use Value: AEC-Q101 qualification ensures reliability over 15-year vehicle life; 1.0 mm height avoids interference with conformal coating or mechanical shields. |
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-E3/5AT | DO-214AC (SMA) package; 13.3 V VBR min; 200 W PPPM; higher clamping voltage (21.5 V) | Larger footprint (2.5 mm height); lower surge rating limits use in high-energy automotive transients | Preferred where board space allows and cost sensitivity outweighs peak power requirement |
| TPSMP13AHM3/85A | Same electrical specs but HE3 suffix replaced with HM3; identical DO-220AA package and AEC-Q101 qualification | No functional difference; HM3 denotes alternate tape-and-reel packaging (13" reel, same 10,000-unit quantity) | Select when sourcing alignment with Vishay's HM3 packaging standard or existing BOM harmonization |
Compared with TPSMP13AHE3/85A, SMAJ13A-E3/5AT offers lower cost but reduced surge robustness and larger footprint, while TPSMP13AHM3/85A provides identical protection performance with packaging variation only-making it a direct form-fit-function alternative for supply chain continuity.

FAQ
What is the clamping voltage of the TPSMP13AHE3/85A under a 10/1000 µs surge?
The TPSMP13AHE3/85A clamps to a maximum of 18.2 V at 22.0 A peak pulse current (IPPM) under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and reflects the actual voltage imposed on the protected circuit during standardized surge testing, ensuring compatibility with 12 V system ICs rated for ≤20 V absolute maximum input.
Is the TPSMP13AHE3/85A suitable for bidirectional signal line protection?
No, the TPSMP13AHE3/85A is a unidirectional TVS diode and must be used only in DC-biased applications where the cathode connects to the protected line and anode to ground. For bidirectional protection (e.g., AC-coupled data lines), a symmetric device such as the SMBJ13CA or a dual-diode array is required - the TPSMP13AHE3/85A does not support reverse conduction.
Does the TPSMP13AHE3/85A meet AEC-Q101 stress test requirements?
Yes, the TPSMP13AHE3/85A is explicitly qualified to AEC-Q101 standards for automotive discrete semiconductors. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life - confirmed in Vishay document 88471 and supported by the "A" suffix and HE3/85A packaging code denoting high-reliability automotive grade.
What is the maximum steady-state power dissipation for the TPSMP13AHE3/85A?
The TPSMP13AHE3/85A has a maximum steady-state power dissipation (PD) of 2.5 W when mounted on an infinite heatsink at TA = 75 °C. Under normal PCB conditions without heatsinking, derating applies per Figure 6 in the datasheet - at 125 °C ambient, usable power drops to approximately 1.25 W, limiting its use to transient-only duty cycles rather than continuous power dissipation.
How is polarity identified on the TPSMP13AHE3/85A package?
Polarity on the TPSMP13AHE3/85A is marked by a visible color band on the cathode end of the DO-220AA (SMP) package. This band aligns with the cathode terminal, which must be connected to the signal line being protected; the unmarked end is the anode and connects to ground or the return path. Correct orientation is essential for proper unidirectional clamping function.
