Product details
Overview
TPSMP36AHM3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the PAR® family, designed for high-reliability automotive and industrial surge protection. It features a 34.2 V to 37.8 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 185 °C maximum junction temperature, and SMP (DO-220AA) package with 1.0 mm profile - used to protect sensor signal lines and drive transistors in ADAS ECUs.
For engineers reviewing the TPSMP36AHM3_A/H datasheet, TPSMP36AHM3_A/H pinout, TPSMP36AHM3_A/H application, or TPSMP36AHM3_A/H equivalent, key selection criteria include clamping voltage (49.9 V at IPPM), low incremental surge resistance, AEC-Q101 qualification, MSL Level 1 rating, and unidirectional polarity for DC-biased interfaces.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve stable breakdown behavior and low leakage (<1 µA at VWM) across -65 °C to +185 °C operating range. Its junction passivation enables robust performance under repeated surge stress while maintaining tight VBR tolerance (±5 %) and low temperature coefficient (0.099 %/°C).
The device operates as a clamping-type protector: during transient events exceeding VWM, it avalanches to limit voltage across protected circuitry. With 8.0 A peak pulse current (IPPM) and 2.5 V max forward voltage at 25 A, it supports fast response (<1 ns) and low forward conduction loss in high-current surge scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V - defines minimum avalanche initiation and maximum guaranteed breakdown threshold at 1 mA test current |
| VWM | 30.8 V - maximum continuous reverse voltage before significant leakage; sets upper limit for DC bias in protected line |
| VC @ IPPM | 49.9 V - clamped voltage during 8.0 A 10/1000 µs surge; determines worst-case overvoltage seen by downstream IC |
| PPPM | 400 W - peak pulse power handling for 10/1000 µs waveform; enables protection against ISO 7637-2 Pulse 1/2/5a surges |
| TJ max | +185 °C - extended junction temperature rating supports under-hood automotive placement without derating |
| Package | SMP (DO-220AA) - 2.18 mm × 3.61 mm footprint, 1.0 mm height, halogen-free, RoHS-compliant, AEC-Q101 qualified |
| Polarity | Unidirectional - cathode-band marked; suitable only for DC-biased or single-polarity signal lines |
Pinout & Package
TPSMP36AHM3_A/H is a two-terminal surface-mount TVS diode in the SMP (DO-220AA) package. The cathode is marked by a color band on the body; the anode is the opposite end. No internal leads or multiple pins - terminals are soldered directly to PCB pads per JEDEC MO-290.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when VLINE exceeds VBR |
| Anode (unbanded end) | Reference node | Typically tied to system ground or low-impedance return path; completes clamping loop during avalanche |
Key Features
| Feature | Design Value |
|---|---|
| Junction passivation | Stabilizes VBR over temperature and lifetime; reduces parameter drift under thermal cycling and humidity stress |
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements including HTGB, HTRB, and temperature cycling |
| MSL Level 1 (260 °C) | Enables standard SMT reflow without moisture sensitivity concerns; no baking required prior to assembly |
| Low profile (1.0 mm height) | Reduces board clearance issues in space-constrained modules such as radar sensors and camera ECU housings |
| Halogen-free & RoHS | Complies with automotive material compliance standards (e.g., ELV, IMDS) and global environmental regulations |
Applications

IC Role / Device Role / Timing Role: Standoff-rated TVS placed between input terminal and controller GPIO to shunt surge current to common ground. Use Value: 30.8 V VWM allows reliable operation across full 20–30 V industrial supply range while blocking normal leakage. |
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 (Vishay) | DO-214AC (SMA) package; 400 W PPPM; VC = 58.1 V at same IPPM; 2.5 mm height | Higher clamping voltage increases risk to downstream ICs; larger footprint limits layout density | Select when legacy SMA footprint compatibility is required and board height >2.5 mm is acceptable |
| TPSMA6.8A-Q (ON Semiconductor) | AEC-Q101 qualified; DO-214AC; VBR = 6.45–7.14 V; PPPM = 400 W; VC = 11.5 V - not voltage-matched to TPSMP36AHM3_A/H | Designed for low-voltage logic rails (e.g., 5 V MCU I/O), not 24–36 V power/signal lines | Use only for sub-12 V systems; not interchangeable due to VBR mismatch and different application voltage class |
Compared with SMAJ36A-E3/5A and TPSMA6.8A-Q, TPSMP36AHM3_A/H delivers lower clamping (49.9 V vs. 58.1 V), smaller footprint (2.18 × 3.61 mm vs. 4.5 × 2.7 mm), and lower profile (1.0 mm vs. 2.5 mm), making it optimal for next-gen compact automotive modules where voltage margin and space are critical.

FAQ
What is the breakdown voltage tolerance for TPSMP36AHM3_A/H?
The TPSMP36AHM3_A/H has a specified breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1.0 mA test current, representing a ±5 % tolerance around the nominal 36 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margin design in safety-critical automotive circuits.
Is TPSMP36AHM3_A/H compatible with lead-free reflow processes?
Yes, TPSMP36AHM3_A/H is fully compatible with lead-free reflow processes. It meets MSL Level 1 per J-STD-020 with a maximum peak temperature of 260 °C, requires no pre-baking, and features matte tin-plated terminals qualified to J-STD-002 and JESD 22-B102 for reliable solderability and whisker resistance.
Does TPSMP36AHM3_A/H support bidirectional transient suppression?
No, TPSMP36AHM3_A/H is a unidirectional TVS diode, intended only for DC-biased or single-polarity signal/power lines. It does not provide symmetrical clamping for AC or bipolar transients. For bidirectional protection, a separate device such as the TPSMP36CA variant (not this part number) would be required.
What is the maximum clamping voltage of TPSMP36AHM3_A/H under surge conditions?
The maximum clamping voltage (VC) of TPSMP36AHM3_A/H is 49.9 V at its rated peak pulse current (IPPM) of 8.0 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the SMP (DO-220AA) package of TPSMP36AHM3_A/H compare to SMA (DO-214AC) in thermal performance?
The SMP (DO-220AA) package of TPSMP36AHM3_A/H offers comparable steady-state thermal resistance to SMA but achieves higher power density due to its reduced footprint (2.18 × 3.61 mm vs. 4.5 × 2.7 mm) and lower height (1.0 mm). Its optimized pad layout supports efficient heat spreading on FR-4 PCBs, enabling 400 W pulse handling despite smaller size.
