Product details
Overview
TPSMP13AHM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-energy surge protection on power and signal lines. It features a 12.4 V to 13.7 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), 22.0 A peak pulse current (IPPM), and clamps to ≤18.2 V at rated surge. It is AEC-Q101 qualified and rated for automotive-grade operation up to TJ = 185 °C.
For engineers reviewing the TPSMP13AHM3/85A datasheet, TPSMP13AHM3/85A pinout, TPSMP13AHM3/85A application, or TPSMP13AHM3/85A equivalent, this device is selected for robust ESD/surge protection in automotive ECUs, industrial sensor interfaces, and DC power rail conditioning where low-profile surface-mount reliability and MSL Level 1 reflow compatibility are required.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective clamping of fast-rising transients such as ISO 7637-2 pulses and IEC 61000-4-5 surges. Its unidirectional configuration supports DC-biased lines with cathode-anode polarity alignment.
The DO-220AA (SMP) package delivers high power density in a 1.0 mm typical height profile, optimized for automated placement and compatible with J-STD-002/JESD 22-B102 soldering standards. The HM3 suffix confirms halogen-free, RoHS-compliant construction and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 12.4 V / 13.7 V - Ensures reliable turn-on above normal operating voltage while avoiding false triggering on ripple or transients. |
| VC @ IPPM | ≤18.2 V - Clamping voltage limits downstream IC stress during 22.0 A surge events. |
| PPPM | 400 W (10/1000 µs) - Supports high-energy surge immunity per ISO 7637-2 Pulse 5a/b and IEC 61000-4-5 Level 4. |
| IFSM | 40 A - Withstands repetitive 10 ms half-sine surge currents without degradation. |
| TJ max | 185 °C - Enables under-hood automotive deployment and long-term thermal reliability in sealed enclosures. |
| VWM | 11.1 V - Stand-off voltage allows use on 12 V nominal systems with margin for load dump overshoot. |
| Package | DO-220AA (SMP) - 1.0 mm height enables ultra-thin PCB designs; MSL Level 1 supports lead-free reflow at 260 °C peak. |
Pinout & Package
TPSMP13AHM3/85A is a two-terminal unidirectional TVS diode in DO-220AA (SMP) package. Polarity is marked by a color band indicating the cathode terminal. The device has no active control pins - terminals serve only as anode and cathode for transient shunting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Surge current sink node | Connected to protected line; conducts during overvoltage to divert energy to ground or return path. |
| Anode | Reference/return node | Typically tied to system ground or lower-potential rail; completes clamping path during transient event. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements including temperature cycling, HTRB, and ESD. |
| 185 °C junction rating | Enables operation in engine bay, powertrain, and ADAS modules without derating in ambient >125 °C environments. |
| Low-profile DO-220AA package | 1.0 mm height reduces board stack-up and improves airflow in dense power modules. |
| MSL Level 1 rating | Allows single-pass lead-free reflow at 260 °C without preconditioning or baking. |
| Halogen-free & RoHS-compliant (HM3) | Meets global environmental compliance mandates and supports green manufacturing programs. |
Applications
| Automotive Body Control Module (BCM) | Industrial CAN Transceiver Protection |
|---|---|
Use Scenario: Protecting LIN bus and 12 V supply inputs in BCMs exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed at connector entry point before LDO regulators and microcontrollers.

Use Scenario: Protecting 12 V power input of rear-view or surround-view cameras mounted externally. IC Role / Device Role / Timing Role: Unidirectional TVS on camera module power feedthrough, paired with reverse-polarity protection MOSFET. Use Value: 185 °C TJ rating ensures sustained operation in sealed housings subject to solar heating and engine radiant heat. |
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-E3/5AT | DO-214AC (SMA) package; 400 W PPPM; VBR = 14.4–15.9 V; higher VC = 21.2 V | Larger footprint (2.5 mm height); less suitable for ultra-thin automotive modules | Select when legacy SMA layout exists and 1.0 mm height is not constrained. |
| TPSMA6.8A-Q | Same DO-220AA package; lower VBR = 7.13–7.88 V; PPPM = 300 W; AEC-Q101 qualified | Optimized for 5 V/3.3 V rails; insufficient clamping margin for 12 V systems | Choose for low-voltage digital interfaces where tighter VBR tolerance is critical. |
Compared with SMAJ13A-E3/5AT and TPSMA6.8A-Q, the TPSMP13AHM3/85A offers superior height reduction (1.0 mm vs. 2.5 mm), lower clamping voltage (18.2 V vs. 21.2 V), and identical AEC-Q101 qualification - making it optimal for space-constrained 12 V automotive power protection where thermal and mechanical envelope are critical.

FAQ
What is the breakdown voltage range of the TPSMP13AHM3/85A?
The TPSMP13AHM3/85A has a specified breakdown voltage (VBR) range of 12.4 V to 13.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This range ensures consistent turn-on behavior across production lots while providing sufficient margin above 12 V nominal systems to avoid nuisance conduction during normal operation.
Is the TPSMP13AHM3/85A suitable for automotive applications?
Yes, the TPSMP13AHM3/85A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and body electronics applications. Its DO-220AA package meets MSL Level 1 and supports lead-free reflow, fulfilling key automotive manufacturing and reliability requirements.
What is the clamping voltage of the TPSMP13AHM3/85A at its rated peak pulse current?
The TPSMP13AHM3/85A clamps to a maximum of 18.2 V at its rated peak pulse current (IPPM) of 22.0 A under 10/1000 µs waveform conditions. This clamping performance is verified per standard test methods and ensures downstream components remain within safe operating voltage limits during surge events.
Does the TPSMP13AHM3/85A have polarity marking, and how is it identified?
Yes, the TPSMP13AHM3/85A uses a color band to denote the cathode terminal, consistent with industry-standard diode marking. The banded end must be connected toward the protected line side (e.g., 12 V rail), while the anode connects to ground or return path to enable proper unidirectional clamping action.
What packaging format is supplied for the TPSMP13AHM3/85A?
The TPSMP13AHM3/85A is supplied in 13-inch diameter plastic tape and reel format, with a base quantity of 10,000 units per reel. The "85A" in the part number explicitly denotes this delivery mode, supporting high-volume SMT assembly without manual handling or transfer steps.
