Product details
Overview
TPSMB36AHE3/52T from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 36 V breakdown voltage (VBR = 34.2–37.8 V at IT = 1 mA), 30.8 V stand-off voltage (VWM), 49.9 V maximum clamping voltage (VC) at 12 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB36AHE3/52T datasheet, TPSMB36AHE3/52T pinout, TPSMB36AHE3/52T application, or TPSMB36AHE3/52T equivalent, key selection criteria include unidirectional polarity, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, clamping performance under 10/1000 µs surge, and thermal derating above 25 °C ambient.
Technical Context
The TPSMB36AHE3/52T employs passivated anisotropic rectifier technology optimized for high-temperature stability and low incremental surge resistance. Its junction design enables reliable operation at TJ = 185 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
It delivers fast response time (<1 ns) and excellent clamping ratio (VC/VBR ≈ 1.39), with specified reverse leakage ≤1 µA at VWM and ≤5 µA at TJ = 150 °C - critical for low-power sensor rail protection where standby current integrity matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V at 1 mA - defines precise overvoltage triggering threshold for robust system-level ESD/surge immunity |
| VWM | 30.8 V - maximum continuous working voltage without significant leakage; sets upper limit for protected rail nominal voltage |
| VC @ IPPM | 49.9 V at 12 A - clamping voltage during 10/1000 µs surge; determines worst-case stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling capacity; supports repetitive surge events at 0.01% duty cycle |
| TJ max. | +185 °C - enables use in under-hood automotive modules and high-ambient industrial enclosures without thermal derating penalties |
| Polarity | Unidirectional - protects only against positive transients relative to cathode; requires correct orientation in series with power line |
| Package | SMB (DO-214AA) - standardized surface-mount footprint with 0.205" × 0.220" pad layout; compatible with automated SMT assembly |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 rated compound, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Anode of internal PN junction | Connected to protected circuit's higher-potential side (e.g., VIN); absorbs positive transients toward ground |
| Anode | Cathode of internal PN junction | Connected to system ground or return path; completes clamping current loop during overvoltage event |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for engine control, ADAS, and body electronics |
| Junction passivation | Reduces surface leakage and improves long-term stability under humid/high-bias conditions - critical for outdoor telecom and industrial gateways |
| Low incremental surge resistance | Minimizes VC overshoot during fast-rising transients - enhances protection margin for 3.3 V/5 V logic interfaces |
| MSL Level 1 rating | Supports lead-free reflow up to 260 °C peak without moisture-induced popcorning - eliminates pre-bake requirement in high-volume manufacturing |
| 185 °C TJ capability | Enables placement near heat sources (e.g., power MOSFETs, DC-DC inductors) without thermal shutdown or parameter drift |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V/24 V battery-fed ECUs from load dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges above 30.8 V. Use Value: Limits peak stress on LDOs and microcontrollers to ≤49.9 V during ISO 7637-2 Pulse 5a events, preserving functional safety compliance. |
Use Scenario: Shielding analog sensor outputs (e.g., pressure, temperature) from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-leakage TVS mounted at connector entry point to shunt transients before signal conditioning stage. Use Value: Maintains <1 µA reverse leakage at 30.8 V, preventing DC offset errors in precision 24-bit ADC front-ends. |
| Telecom Line Card Surge Suppression | Consumer Power Adapter Input Protection |
Use Scenario: Safeguarding PoE-powered Ethernet ports against lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Paired unidirectional TVS on each DC feed line to clamp differential and common-mode overvoltages. Use Value: Withstands 600 W pulses per IEC 61000-4-5 Combination Wave (10/700 µs), meeting EN 61000-6-2 immunity requirements. |
Use Scenario: Adding secondary surge protection after primary MOV in AC/DC adapters for smart home devices. IC Role / Device Role / Timing Role: Fast-response TVS supplementing slower-acting MOV to handle fast-rising ESD and switching spikes. Use Value: Sub-1 ns response time captures transients that bypass MOV thermal inertia, reducing failure rate in Class II double-insulated designs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | 400 W PPPM, VC = 58.1 V @ 6.9 A, same SMB package | Limited to lower-energy surges; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 600 W headroom |
| SMCJ36A | 1500 W PPPM, VC = 58.1 V @ 25.8 A, larger SMC (DO-214AB) package | Requires PCB layout change; suited for higher-energy industrial mains protection | Choose when system-level surge test levels exceed IEC 61000-4-5 Level 4 (4 kV/2 kA) |
Compared with SMAJ36A and SMCJ36A, the TPSMB36AHE3/52T offers optimal balance of AEC-Q101 compliance, 600 W capability, and SMB footprint - making it the preferred choice for space-constrained automotive and industrial modules requiring validated reliability without board redesign.

FAQ
What is the AEC-Q101 qualification status of the TPSMB36AHE3/52T?
The TPSMB36AHE3/52T carries full AEC-Q101 qualification, confirmed in Vishay's official documentation (Doc. #88406, Rev. 23-Jan-2024). This includes stress testing for temperature cycling, high-temperature reverse bias, and surge endurance - validating its suitability for automotive powertrain, chassis, and body electronics applications where reliability is mission-critical. The HE3 suffix explicitly denotes AEC-Q101 compliance.
Does the TPSMB36AHE3/52T support lead-free reflow soldering?
Yes, the TPSMB36AHE3/52T meets J-STD-020 MSL Level 1 and is rated for lead-free reflow with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing - ensuring robust solder joint integrity in high-volume SMT production without pre-bake requirements.
What is the maximum clamping voltage of the TPSMB36AHE3/52T under standard surge conditions?
The TPSMB36AHE3/52T has a maximum clamping voltage (VC) of 49.9 V at 12 A peak pulse current (IPPM) using the industry-standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during surge events - essential for ensuring downstream ICs remain within absolute maximum ratings.
How does the TPSMB36AHE3/52T differ from the TPSMB36AHM3/52T variant?
The TPSMB36AHE3/52T is RoHS-compliant and AEC-Q101 qualified, while the TPSMB36AHM3/52T adds halogen-free construction alongside RoHS compliance and AEC-Q101 qualification. Both share identical electrical specs, thermal performance (TJ = 185 °C), and SMB packaging - the HM3 variant is selected only when halogen-free material content is mandated by environmental policy or regional regulations.
Can the TPSMB36AHE3/52T be used in bidirectional protection configurations?
No - the TPSMB36AHE3/52T is strictly unidirectional, as confirmed in Vishay's datasheet (Section "FEATURES": "Available in unidirectional polarity only"). For bidirectional transient suppression, a separate pair of TPSMB36AHE3/52T devices must be used in back-to-back configuration, or a dedicated bidirectional TVS such as the TPSMB36CA should be selected instead.
