Product details
Overview
P6SMB36AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features 34.2 V to 37.8 V breakdown voltage (VBR) at 1 mA test current, 30.8 V maximum stand-off voltage (VWM), and clamps to 49.9 V at 12.0 A peak pulse current under 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB36AHE3/52 datasheet, P6SMB36AHE3/52 pinout, P6SMB36AHE3/52 application, or P6SMB36AHE3/52 equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 600 W peak pulse power rating, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that conducts above its breakdown voltage to divert transient energy away from downstream circuitry. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the unidirectional configuration provides forward conduction path only during reverse overvoltage events.
The device is rated for 600 W peak pulse power (10/1000 µs), 100 A non-repetitive forward surge current (8.3 ms half-sine), and operates across -65 °C to +150 °C junction temperature range. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), requiring appropriate PCB copper area for thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 34.2 V / 37.8 V at 1 mA - defines precise clamping onset threshold for overvoltage protection |
| VWM | 30.8 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 49.9 V at 12.0 A - clamped voltage seen by protected circuit during worst-case 10/1000 µs surge |
| PPPM | 600 W - peak transient power handling capability per JEDEC standard waveform |
| IPPM | 12.0 A - maximum single-pulse current the device can safely shunt without degradation |
| TJ max | +150 °C - maximum junction temperature enabling use in high-temperature industrial environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 0.220" × 0.205" footprint and matte tin-plated leads |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Dimensions: 0.220" × 0.205" × 0.096" (5.59 mm × 5.21 mm × 2.44 mm). Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side of protected line; enables normal forward bias operation when needed |
| Cathode | Reverse-biased clamping terminal | Marked with band; connected to higher-potential side; conducts during overvoltage to clamp to VC |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage (<1 µA at VWM) over lifetime and temperature |
| 600 W peak pulse power | Handles high-energy transients such as ISO 7637-2 Load Dump pulses without failure |
| MSL Level 1 (260 °C) | Compatible with standard lead-free reflow profiles without moisture sensitivity concerns |
| Low clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage stress on protected ICs compared to higher-ratio suppressors |
Applications
| Industrial Power Supply Protection | Automotive Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V DC input rails against load dump and inductive switching spikes in PLC modules and motor drives. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and ground to clamp transients before they reach DC-DC converters and microcontrollers. Use Value: Limits voltage excursion to ≤49.9 V during 12.0 A surges, preventing latch-up or gate oxide damage in downstream 36 V-rated components. |
Use Scenario: Safeguarding analog front-end inputs of pressure/temperature sensors in engine control units exposed to battery transients. IC Role / Device Role / Timing Role: Standoff voltage (30.8 V) matches nominal 24 V sensor supply; clamps fast ESD and ISO 10605 events at sensor pins. Use Value: Sub-50 V clamping enables direct interface with 5 V or 3.3 V ADC inputs via series resistor, eliminating need for additional level-shifting. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Control |
Use Scenario: Shielding Ethernet PHY power rails and RS-485 bus lines from lightning-induced surges in outdoor telecom cabinets. IC Role / Device Role / Timing Role: Mounted at board edge near connectors to absorb incoming transients before reaching communication ICs. Use Value: 600 W rating handles multi-kV induced surges per IEC 61000-4-5; low capacitance avoids signal integrity degradation on 100 Mbps links. |
Use Scenario: Suppressing commutation spikes generated by brushed DC motors in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Placed across motor terminals or H-bridge outputs to clamp flyback voltage during PWM switching. Use Value: Fast response (<1 ns) prevents voltage overshoot beyond MOSFET VDSS, reducing risk of avalanche failure in 60 V-rated switches. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/52 | Same VWM (30.8 V), identical SMB package, but rated for 400 W PPPM and lower IPPM (8.2 A) | Limited to lower-energy transients; not suitable for ISO 7637-2 Pulse 5a load dump | Select when cost sensitivity outweighs peak power requirement and layout space allows derating margin |
| 1.5SMC36A | Higher PPPM (1500 W), larger SMC (DO-214AB) package, same VBR range but 2.5× footprint area | Requires PCB redesign; better suited for primary-side AC/DC input protection | Choose only if system-level surge testing exceeds 600 W requirements and board space permits larger package |
Compared with SMAJ36A-E3/52 and 1.5SMC36A, P6SMB36AHE3/52 delivers optimal balance of AEC-Q101 qualification, 600 W capability, and compact SMB footprint - making it preferred for space-constrained automotive and industrial control boards where both reliability and size matter.

FAQ
What is the breakdown voltage tolerance of P6SMB36AHE3/52?
The P6SMB36AHE3/52 has a specified breakdown voltage (VBR) range of 34.2 V to 37.8 V at 1 mA test current, representing ±5% tolerance around the nominal 36 V rating. This tight tolerance ensures consistent clamping behavior across production lots and supports predictable overvoltage protection design margins in safety-critical systems.
Is P6SMB36AHE3/52 RoHS-compliant and halogen-free?
Yes, P6SMB36AHE3/52 carries the HE3 suffix, indicating it is RoHS-compliant and AEC-Q101 qualified. However, it is not halogen-free - that designation applies only to HM3-suffixed variants. The HE3 version uses standard molding compound meeting UL 94 V-0 flammability rating and JESD 201 Class 2 whisker resistance.
Can P6SMB36AHE3/52 be used in bidirectional configurations?
No, P6SMB36AHE3/52 is strictly unidirectional, as indicated by the "A" suffix and presence of cathode band marking. For bidirectional operation, Vishay specifies part numbers ending in "CA", such as P6SMB36CAHE3/52, which lacks polarity marking and conducts symmetrically in both directions.
What is the maximum reverse leakage current of P6SMB36AHE3/52 at rated VWM?
At its maximum stand-off voltage of 30.8 V and ambient temperature of 25 °C, the P6SMB36AHE3/52 exhibits ≤1.0 µA reverse leakage current (ID). This low leakage preserves efficiency in always-on circuits and avoids false triggering in high-impedance sensor bias networks.
Does P6SMB36AHE3/52 require derating at elevated ambient temperatures?
Yes, P6SMB36AHE3/52 must be derated above 25 °C ambient per Figure 2 in the datasheet. At 85 °C ambient, its peak pulse power drops to ~420 W (70% of 600 W), and at 125 °C, it falls to ~240 W (40%). Derating ensures junction temperature remains within the +150 °C limit during repetitive surge events.
