Product details
Overview
TPSMP36AHM3/85A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial overvoltage protection. It features a 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 52.0 V clamping voltage (VC) at 8.0 A peak pulse current, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the TPSMP36AHM3/85A datasheet, TPSMP36AHM3/85A pinout, TPSMP36AHM3/85A application, or TPSMP36AHM3/85A equivalent, this device delivers verified 400 W peak pulse power (10/1000 µs), 185 °C junction temperature capability, low-profile 1.0 mm height, and MSL Level 1 moisture sensitivity - critical for automated SMT assembly in harsh-environment electronics.
Technical Context
The TPSMP36AHM3/85A employs passivated anisotropic rectifier technology optimized for fast response time and low incremental surge resistance. Its unidirectional configuration enables robust reverse-biased clamping during transients while maintaining low leakage (<1.0 µA at VWM) across its operating temperature range.
Designed for PCB-mounted protection with 5.0 mm × 5.0 mm copper pads per terminal, it sustains 40 A non-repetitive forward surge current (IFSM) and operates reliably from –65 °C to +185 °C. The device meets JESD201 Class 2 whisker testing and UL 94 V-0 flammability requirements via halogen-free molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - ensures precise triggering above normal 24 V system rail with ±5 % tolerance |
| VWM | 30.8 V - blocks normal operating voltage while allowing margin before clamping onset |
| VC @ IPPM | 49.9 V at 8.0 A - limits downstream IC voltage stress during 10/1000 µs surge events |
| PPPM | 400 W - supports high-energy transients common in automotive load-dump and ISO 7637-2 pulses |
| TJ max | +185 °C - enables placement near heat sources (e.g., power modules, ECUs) without derating |
| IR @ VWM | <1.0 µA - minimizes standby power loss and avoids false triggering in low-current sensor circuits |
| Package | DO-220AA (SMP) - 1.0 mm profile allows dense layout in space-constrained modules |
Pinout & Package
DO-220AA (SMP) surface-mount package with cathode indicated by color band; matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path during surge | Connected to protected line (e.g., 24 V supply rail); conducts transient energy to ground when clamped |
| Cathode | Reverse-biased clamping node | Connected to system ground; defines polarity-sensitive protection direction and sets VWM/VBR threshold |
Key Features
| Feature | Design Value |

| 185 °C junction rating | Eliminates thermal derating in engine control units and powertrain modules operating above 150 °C ambient |
| Low-profile 1.0 mm height | Reduces board-level mechanical interference in stacked modules and compact ECU housings |
| Halogen-free & RoHS-compliant | Meets EU ELV Directive and automotive OEM material compliance requirements (e.g., GMW3172, Ford WSS-M99P9999-A1) |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply inputs of body control modules (BCM) against load dump and jump-start surges per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input to clamp transients before LDOs or PMICs. Use Value: Withstands 400 W peak pulse power and 185 °C operation, enabling direct placement on high-temp PCB zones near fuse boxes. | Use Scenario: Safeguarding analog outputs of pressure/temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Reverse-biased clamping element on 4–20 mA current loop lines to absorb ESD and inductive switching spikes. Use Value: Sub-1 µA leakage at 30.8 V VWM prevents signal offset errors; DO-220AA footprint fits tight 2.54 mm pitch terminal blocks. |
| Automotive Lighting Driver Protection | Industrial Motor Drive Gate Control |
Use Scenario: Shielding LED driver ICs in adaptive front lighting systems (AFS) from alternator ripple and relay coil flyback. IC Role / Device Role / Timing Role: Fast-response TVS on high-side switch output to limit voltage overshoot during PWM turn-off. Use Value: 49.9 V clamping at 8.0 A ensures MOSFET drain voltage stays below 60 V rating during 10/1000 µs transients. | Use Scenario: Protecting isolated gate drivers in servo motor inverters from dv/dt-induced coupling and bus transients. IC Role / Device Role / Timing Role: Clamping component on gate drive supply rails (e.g., 15 V bias) to prevent driver latch-up or bootstrap capacitor overvoltage. Use Value: 30.8 V VWM provides 2× margin over 15 V rail; 1.0 mm height avoids interference with adjacent gate driver ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A | DO-214AC (SMA) package; 36.0–40.0 V VBR; 400 W PPPM; 150 °C TJ max | Larger 2.3 mm height; lower thermal endurance in high-ambient zones | Select when legacy SMA footprint exists and 185 °C operation is not required |
| TPSMA6.8A-Q | Same DO-220AA package; 6.45–7.14 V VBR; 300 W PPPM; AEC-Q101 qualified | Lower voltage rating; insufficient for 24 V systems requiring ≥30 V VWM | Use only for 5 V or 12 V rail protection where tighter VBR tolerance is needed |
Compared with SMAJ36A-E3/5A, TPSMP36AHM3/85A offers superior thermal robustness (185 °C vs. 150 °C) and smaller footprint; versus TPSMA6.8A-Q, it provides higher voltage rating and 400 W surge capacity essential for 24 V automotive power nets.
