Product details
Overview
P6SMB160AHE3_A/H 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 a 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - deployed in automotive power rail protection and industrial sensor interface circuits.
For engineers reviewing the P6SMB160AHE3_A/H datasheet, P6SMB160AHE3_A/H pinout, P6SMB160AHE3_A/H application, or P6SMB160AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 to +150 °C), and compliance with J-STD-020 MSL level 1 reflow profile.
Technical Context
This TVS diode operates as a clamping device in reverse-biased configuration, activating when transient voltage exceeds its breakdown threshold (VBR = 152–168 V). Its low incremental surge resistance ensures minimal voltage overshoot during fast transients, while glass-passivated junction enhances reliability under repetitive surge stress.
The device is rated for 600 W peak pulse power under standardized 10/1000 μs waveform, with derating above 25 °C ambient per Fig. 2. Its unidirectional polarity and cathode band marking enable correct PCB orientation, and it meets JEDEC JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements.

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and inductive switching transients per ISO 16750-2. IC Role / Device Role / Timing Role: Unidirectional clamping TVS placed between power input and ground, activated within nanoseconds of overvoltage event.

Use Value: Withstands 100 A IFSM surge and operates up to +150 °C, ensuring reliability in thermally constrained adapter enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/52 | Same VWM (136 V), lower PPPM (400 W), SMA package (larger RθJA = 130 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump | Select if cost-sensitive and thermal margin allows higher junction temperature rise |
| 1.5SMC160A | Same VWM and VC, but SMC package (higher power rating: 1500 W), larger footprint | Better suited for high-reliability industrial mains input stages with space allowance | Choose when 1500 W surge capacity is required and PCB area permits SMC outline |
Compared with P6SMB160AHE3_A/H, SMAJ160A-E3/52 offers reduced surge handling and thermal performance in a smaller package, while 1.5SMC160A delivers higher power rating in a larger, non-AEC-Q101-qualified SMC form factor - making P6SMB160AHE3_A/H the optimal balance of automotive qualification, SMB footprint, and 600 W capability.

FAQ
What is the clamping voltage of P6SMB160AHE3_A/H at its rated peak pulse current?
The P6SMB160AHE3_A/H has a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM) of 2.7 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB160AHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is P6SMB160AHE3_A/H qualified for automotive applications?
Yes, P6SMB160AHE3_A/H is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's datasheet 88370. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD, validating its suitability for automotive powertrain, body control, and ADAS subsystems. The P6SMB160AHE3_A/H meets the reliability requirements for under-hood and cabin-mounted electronics.
What is the thermal resistance of P6SMB160AHE3_A/H, and how does it affect PCB layout?
The P6SMB160AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" x 0.2" (5.0 mm x 5.0 mm) copper pads per terminal. This value directly impacts maximum allowable power dissipation: exceeding 5.0 W continuous power risks junction temperature exceeding +150 °C. To maintain thermal safety, PCB layout must replicate the specified pad dimensions and avoid excessive trace narrowing near the SMB terminals.
How does the unidirectional configuration of P6SMB160AHE3_A/H influence circuit placement?
The unidirectional configuration of P6SMB160AHE3_A/H requires correct orientation: the cathode (marked by a band) must connect to the line being protected, and the anode to ground or reference potential. Reversal prevents clamping action and may cause catastrophic failure under forward surge. This polarity constraint makes P6SMB160AHE3_A/H unsuitable for AC-coupled or bidirectional signal lines unless paired with complementary devices - unlike bidirectional variants such as P6SMB160CA.
What is the maximum peak forward surge current rating for P6SMB160AHE3_A/H?
The P6SMB160AHE3_A/H is rated for a maximum non-repetitive peak forward surge current (IFSM) of 100 A at 8.3 ms single half-sine wave, per JEDEC standards. This rating applies only in forward-biased fault conditions (e.g., accidental reverse PCB assembly), not during normal reverse-biased clamping operation. The P6SMB160AHE3_A/H leverages this robustness to survive miswiring events without degradation, supporting manufacturing resilience.
