Product details
Overview
P6SMB160A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to 219 V at 2.7 A peak pulse current and is used for overvoltage protection of MOSFETs, ICs, and sensor signal lines in industrial power supplies and telecom interfaces.
For engineers reviewing the P6SMB160A-E3/52 datasheet, P6SMB160A-E3/52 pinout, P6SMB160A-E3/52 application, or P6SMB160A-E3/52 equivalent, key selection criteria include unidirectional polarity, 136 V maximum reverse leakage at 160 V standoff, 150 °C max junction temperature, RoHS-compliant matte tin plating, and MSL Level 1 moisture sensitivity rating.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (152–168 V), limiting transient energy to protected downstream circuitry. Its low incremental surge resistance and fast response time ensure effective suppression of ESD and inductive switching spikes.
The device uses a glass-passivated silicon junction and is mounted on 5.0 mm × 5.0 mm copper pads per terminal to sustain 600 W peak pulse power under JEDEC-standard 10/1000 μs waveform conditions with 0.01% duty cycle. Thermal resistance is 100 °C/W junction-to-ambient and 20 °C/W junction-to-lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during 600 W transient; critical for IC voltage tolerance margining. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustained single-pulse energy handling capability; validates robustness against lightning and load-switch surges. |
| ID (Reverse Leakage) | 1.0 μA max at 136 V - Minimal standby power loss and signal integrity impact in high-impedance sensing paths. |
| TJ max | 150 °C - Enables reliable operation in enclosed industrial enclosures or near heat-generating components. |
| RθJA | 100 °C/W - Requires thermal pad layout per datasheet (0.2" × 0.2" copper) to maintain safe junction temperature under repeated pulses. |
Pinout & Package

|---|---|
|
Use Scenario: Protecting gate drivers and feedback sensors from flyback voltage spikes generated by IGBT/MOSFET switching in variable-frequency drives. IC Role / Device Role / Timing Role: Unidirectional TVS placed between gate driver output and power switch gate, clamping negative-going transients to prevent gate oxide damage. Use Value: Limits transient voltage to ≤219 V, ensuring gate-source voltage stays within ±20 V absolute maximum rating of common 650 V SiC MOSFETs. |
Use Scenario: Shielding RS-485 transceivers and PHY layer components from induced surges on outdoor telecom wiring exposed to lightning coupling. IC Role / Device Role / Timing Role: Primary-level TVS on differential bus lines (A/B), shunting surge energy before it reaches transceiver ESD structures. Use Value: Withstands 600 W pulses while maintaining <1.0 μA leakage at 136 V, preserving signal integrity and bias stability on high-impedance data lines. |
| Power Supply Input Stage | Sensor Signal Conditioning |
|
Use Scenario: Safeguarding AC-DC converter front-end rectifiers and PFC controllers against line surges per IEC 61000-4-5 Level 3 (2 kV/1 kA). IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor input, activated after MOV clamping to handle residual fast-rising edges. Use Value: Fast response time and low clamping voltage (219 V) reduce stress on 400 V-rated electrolytic capacitors and bridge rectifiers during repetitive surges. |
Use Scenario: Protecting analog front-ends of pressure, temperature, or current sensors in factory automation systems subject to relay coil kickback. IC Role / Device Role / Timing Role: Low-leakage (1.0 μA) unidirectional TVS on sensor output line, referenced to local ground to suppress sub-100 ns transients. Use Value: Prevents ADC saturation and op-amp latch-up without introducing offset error or bandwidth degradation due to minimal parasitic capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A | Same VWM (136 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 150 °C/W) | Limited to lower-energy transients; less suitable for industrial motor drive snubbing where 600 W margin is required. | Select P6SMB160A-E3/52 when board space allows larger SMB package and full 600 W surge rating is mandatory. |
| 1.5SMC160A | Same VWM/VBR/VC specs, but SMC (DO-214AB) package - 2.5× larger footprint, lower RθJA (60 °C/W), higher IFSM (200 A) | Better thermal performance for high-duty-cycle environments; overkill for space-constrained telecom modules. | Choose P6SMB160A-E3/52 for balanced surge capability and compactness in consumer/industrial PCBs with moderate thermal budget. |
Compared with SMAJ160A and 1.5SMC160A, P6SMB160A-E3/52 delivers optimal trade-off between 600 W pulse handling, SMB footprint compatibility, and manufacturability in automated SMT lines - especially where JEDEC-compliant MSL Level 1 reflow and RoHS compliance are required.

FAQ
What is the clamping voltage of P6SMB160A-E3/52 at its rated peak pulse current?
The P6SMB160A-E3/52 has a maximum clamping voltage (VC) of 219 V at its specified peak pulse current (IPPM) of 2.7 A under a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is P6SMB160A-E3/52 RoHS-compliant and lead-free?
Yes, P6SMB160A-E3/52 is RoHS-compliant and lead-free. The "E3" suffix explicitly denotes Vishay's commercial-grade, RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability requirements and JESD 201 Class 2 whisker resistance testing.
What is the maximum operating junction temperature for P6SMB160A-E3/52?
The maximum operating junction temperature (TJ max) for P6SMB160A-E3/52 is +150 °C. This rating enables reliable operation in enclosed industrial enclosures or near heat-generating components, provided the PCB layout follows Vishay's recommended 0.2" × 0.2" copper pad per terminal to maintain thermal resistance at 100 °C/W.
Does P6SMB160A-E3/52 have AEC-Q101 qualification?
The base P6SMB160A-E3/52 is not AEC-Q101 qualified; however, the automotive-grade variant P6SMB160AHE3_B/H is fully AEC-Q101 qualified. That version retains identical electrical specs but adds extended reliability testing for automotive under-hood and body-control module applications.
What is the reverse leakage current of P6SMB160A-E3/52 at its standoff voltage?
At its maximum standoff voltage (VWM) of 136 V, P6SMB160A-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor and communication circuits while minimizing standby power loss.
