Product details
Overview
TPSMP13HM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of signal lines and power rails. It features 13 V breakdown voltage (VBR min/max: 11.7 V / 14.3 V), 400 W peak pulse power (10/1000 µs), 21.1 A peak pulse current (IPPM), and clamps to ≤19.0 V at rated surge. Used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the TPSMP13HM3/85A datasheet, TPSMP13HM3/85A pinout, TPSMP13HM3/85A application, or TPSMP13HM3/85A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 185 °C junction rating, low-profile 1.0 mm height, and MSL Level 1 reflow compatibility - all critical for automotive-grade PCB-level ESD and surge protection design.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5). Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (<1 µA at VWM = 10.5 V).
Thermal performance is enhanced by TJ max = 185 °C and derating per Fig. 2, supporting operation in under-hood automotive environments. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 molding compound requirements, confirming suitability for automated SMT assembly and long-term reliability in harsh conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7 V / 14.3 V - defines precise clamping onset threshold for circuit-level overvoltage detection and protection triggering |
| VWM | 10.5 V - maximum continuous reverse operating voltage; ensures no conduction during normal system operation |
| IPPM | 21.1 A - peak surge current handling capability with 10/1000 µs waveform; determines survivability against ISO 7637-2 Pulse 1/2/5a |
| VC @ IPPM | ≤19.0 V - clamped voltage under full surge; sets upper bound on protected IC's voltage stress during transient events |
| PPPM | 400 W - peak pulse power dissipation capacity; enables robust protection against high-energy transients without thermal runaway |
| TJ max | 185 °C - maximum junction temperature rating; supports extended operation in automotive under-hood and industrial control cabinet environments |
| Package | DO-220AA (SMP) - ultra-low-profile surface-mount package (1.0 mm typical height) compatible with fine-pitch automated placement |
Pinout & Package
TPSMP13HM3/85A uses the DO-220AA (SMP) package: a two-terminal, unidirectional surface-mount device with cathode indicated by a color band. Terminals are matte tin-plated, solderable per J-STD-002 and JESD22-B102, and qualified to JESD201 Class 2 for whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point during clamping | Connected to protected line (e.g., CAN_H, LIN, sensor output); conducts when transient exceeds VBR |
| Cathode | Reverse-biased terminal; marked with color band | Connected to ground or lower-potential rail; establishes unidirectional clamping direction and defines polarity-sensitive placement |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, body electronics, and ADAS sensor interfaces |
| Junction passivation optimized design | Reduces leakage drift and improves long-term stability under thermal cycling and humidity stress |
| 185 °C junction temperature rating | Enables reliable operation in under-hood environments where ambient temperatures exceed 125 °C |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow without moisture-related popcorn failure or delamination |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ESD), improving protection margin |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VBR range (11.7–14.3 V), but SMA package (2.5 mm height); lower PPPM = 400 W only at 25 °C, derates faster above 75 °C | Less suitable for space-constrained automotive modules; requires larger PCB footprint and higher profile | Select TPSMP13HM3/85A when board height <1.1 mm is required or AEC-Q101 qualification is mandatory |
| TPSMAJ13A | Identical electrical specs and AEC-Q101 qualification, but in DO-214AC (SMA) package; 2.5 mm height vs. 1.0 mm for TPSMP13HM3/85A | Compatible for prototyping or legacy designs using SMA footprints; not drop-in for SMP layouts | Choose TPSMP13HM3/85A for new compact automotive designs needing lowest possible profile and highest thermal robustness |
Compared with SMAJ13A and TPSMAJ13A, the TPSMP13HM3/85A delivers identical clamping performance in a 60 % lower profile package with superior thermal derating above 75 °C and guaranteed AEC-Q101 compliance - making it the preferred choice for next-generation automotive and space-limited industrial protection.

FAQ
What is the breakdown voltage tolerance for TPSMP13HM3/85A?
The TPSMP13HM3/85A has a breakdown voltage (VBR) range of 11.7 V to 14.3 V at 1.0 mA test current, corresponding to ±10 % tolerance around the nominal 13 V rating. This tolerance is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88471 and applies to all units shipped under this part number.
Is TPSMP13HM3/85A suitable for bidirectional transient protection?
No, TPSMP13HM3/85A is strictly unidirectional. Its internal structure and polarity marking (cathode band) support clamping only in reverse bias. For bidirectional protection, Vishay offers the TPSMP13CA variant; the "A" suffix in TPSMP13HM3/85A denotes unidirectional configuration and ±10 % VBR tolerance, not symmetry.
Does TPSMP13HM3/85A meet automotive qualification standards?
Yes, TPSMP13HM3/85A is AEC-Q101 qualified, as explicitly stated in the Features section and Mechanical Data notes of Vishay document 88471. It also meets JESD201 Class 2 whisker resistance, MSL Level 1 reflow, and UL 94 V-0 flammability requirements - all essential for automotive electronics deployment.
What is the maximum clamping voltage of TPSMP13HM3/85A under surge conditions?
The maximum clamping voltage (VC) of TPSMP13HM3/85A is 19.0 V at IPPM = 21.1 A with a 10/1000 µs waveform, per the Electrical Characteristics table. This value represents the worst-case voltage seen by downstream circuitry during full-rated surge events and is measured at TA = 25 °C.
How does the DO-220AA package of TPSMP13HM3/85A compare to SMA in height and thermal performance?
The DO-220AA (SMP) package of TPSMP13HM3/85A has a typical height of 1.0 mm - less than half the 2.5 mm height of standard SMA packages. Its thermal resistance is optimized for PCB-mounted operation with 5.0 mm × 5.0 mm copper pads, enabling better power dissipation per unit volume and improved derating above 75 °C compared to SMA equivalents like SMAJ13A.
