Product details
Overview
TPSMP13HE3/85A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 11.7 V to 14.3 V breakdown voltage (VBR), 19.0 V clamping voltage (VC) at 21.1 A peak pulse current, and 400 W peak pulse power rating for VBR ≥ 13 V. It protects sensor signal lines and drive transistors in automotive ECUs.
For engineers reviewing the TPSMP13HE3/85A datasheet, TPSMP13HE3/85A pinout, TPSMP13HE3/85A application, or TPSMP13HE3/85A equivalent, key selection criteria include AEC-Q101 qualification, 1.0 mm profile for space-constrained PCBs, low incremental surge resistance, and RoHS-compliant matte tin terminations meeting JESD22-B102 solderability.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve excellent clamping capability and very fast response time (<1 ns). Its unidirectional configuration provides reverse-biased overvoltage protection with defined polarity (cathode band marked).
Rated for operation from −65 °C to +185 °C junction temperature, it delivers stable performance under automotive thermal cycling. The device meets MSL Level 1 per J-STD-020 and is qualified to AEC-Q101 for high-reliability automotive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7 V / 14.3 V - Ensures reliable triggering above system operating voltage while avoiding false trips during transients. |
| VC @ IPPM | 19.0 V at 21.1 A - Limits downstream IC voltage stress during ISO 7637-2 pulse 1/2a/5a events. |
| PPPM | 400 W - Sustains high-energy transients common in 12 V automotive power nets. |
| IFSM | 40 A - Withstands repetitive load dump surges without degradation. |
| TJ max | +185 °C - Supports under-hood placement near engines or power modules. |
| Package | DO-220AA (SMP) - 1.0 mm height enables ultra-low-profile layout on compact automotive PCBs. |
| Qualification | AEC-Q101 qualified - Validated for automotive reliability including temperature cycling, HTRB, and ESD. |
Pinout & Package
DO-220AA (SMP) surface-mount package with cathode indicated by color band; two-terminal device with no internal circuitry requiring orientation beyond polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input side of unidirectional clamp | Connected to protected line; conducts only during forward surge (e.g., load dump). |
| Cathode | Output side / reference node | Connected to ground or lower-potential rail; clamps reverse transients to VC. |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables stable VBR and low leakage (<1 µA at VWM) across lifetime and temperature. |
| MSL Level 1 rating | Allows direct placement without baking; compatible with standard reflow profiles up to 260 °C peak. |

| UL 94 V-0 molding compound | Prevents flame propagation in enclosed automotive enclosures during fault conditions. |
| Low profile (1.0 mm typical height) | Reduces board-level mechanical interference in stacked modules and tight-fitting connectors. |
Applications
| Automotive Sensor Protection | Powertrain Control Unit (ECU) Input Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors exposed to battery transients and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between sensor output and microcontroller ADC input. Use Value: Clamps ISO 10605 ESD (±25 kV air) and ISO 7637-2 pulse 1 (−100 V) to <19.0 V, preserving ADC integrity. |
Use Scenario: Shielding digital inputs (e.g., ignition timing signals) in engine control units from load dump and jump-start surges. IC Role / Device Role / Timing Role: Primary transient suppressor on 12 V supply rail feeding MCU I/O buffers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC package (2.79 mm height); 13.0 V nominal VBR; 300 W PPPM; not AEC-Q101 qualified. | Limited to industrial/commercial use; unsuitable for under-hood automotive deployment. | Select when cost sensitivity outweighs automotive qualification and board height constraints. |
| TPSMP13AHE3/85A | Narrower VBR range (12.4 V–13.7 V); identical package, PPPM, and AEC-Q101 status. | Better suited for systems requiring tighter VBR tolerance near 13 V nominal supply rails. | Choose for improved margin against false triggering in 13.5 V nominal systems. |
Compared with SMAJ13A and TPSMP13AHE3/85A, the TPSMP13HE3/85A offers broader VBR tolerance (11.7–14.3 V) for relaxed design margins, maintains full AEC-Q101 compliance, and enables thinner PCB stacking via its 1.0 mm profile-critical for modern ADAS and body electronics modules.

FAQ
What is the clamping voltage of the TPSMP13HE3/85A and how is it measured?
The TPSMP13HE3/85A has a maximum clamping voltage (VC) of 19.0 V at 21.1 A peak pulse current (IPPM) using a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 standards and reflects the voltage seen by downstream circuitry during worst-case transient events. The TPSMP13HE3/85A achieves this clamping performance through low incremental surge resistance and optimized chip geometry.
Is the TPSMP13HE3/85A suitable for bidirectional transient protection?
No, the TPSMP13HE3/85A is a unidirectional TVS diode and must be used with correct polarity-cathode connected to ground or reference rail. It does not provide symmetrical clamping for both positive and negative transients. For bidirectional protection, a separate device such as the TPSMP13AH (AEC-Q101 qualified bidirectional variant) is required. The TPSMP13HE3/85A datasheet explicitly specifies "Uni-direction only" in its features.
Does the TPSMP13HE3/85A meet automotive reliability standards?
Yes, the TPSMP13HE3/85A is AEC-Q101 qualified and rated for operation from −65 °C to +185 °C junction temperature. It passes automotive-specific stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per ISO 10605. The HE3 suffix confirms high-reliability automotive grade per Vishay's internal qualification protocol.
What is the significance of the "85A" in TPSMP13HE3/85A?
The "85A" denotes the preferred packaging code: 13-inch diameter plastic tape and reel, containing 10,000 units. This format supports high-volume automated SMT placement. The alternative "84A" code indicates 7-inch reel (3,000 units). Both share identical electrical and mechanical specifications-the "85A" refers solely to packaging and quantity, not performance or qualification.
How does the DO-220AA package of the TPSMP13HE3/85A compare to SMA or SMB packages?
The DO-220AA (SMP) package of the TPSMP13HE3/85A measures just 1.0 mm typical height-less than half the height of SMA (2.29 mm) and SMB (2.79 mm) packages. Its footprint is also smaller (2.67 mm × 1.15 mm vs. SMA's 4.57 mm × 2.79 mm), enabling denser layouts. Unlike SMA/SMB, DO-220AA is optimized for low-inductance, high-current transient handling in automotive applications.
