Product details
Overview
P6SMB160CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 179 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It provides clamping protection for signal lines and power rails in automotive sensor interfaces and industrial control I/O.
For engineers reviewing the P6SMB160CAHE3/5B datasheet, P6SMB160CAHE3/5B pinout, P6SMB160CAHE3/5B application, or P6SMB160CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 219 V maximum clamping voltage at rated surge current, and compatibility with automated SMT assembly on standard PCB pads.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing ESD and inductive switching spikes.
The P6SMB160CAHE3/5B is rated for repetitive 10/1000 μs surges at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160CA | Same VWM (160 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary. |

FAQ
What is the clamping voltage of P6SMB160CAHE3/5B at its rated peak pulse current?
The P6SMB160CAHE3/5B has a maximum clamping voltage (VC) of 219 V at its rated peak pulse current (IPPM) of 2.7 A with a 10/1000 μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is guaranteed across the full operating temperature range and remains stable due to the device's glass-passivated junction structure.
Is P6SMB160CAHE3/5B suitable for automotive applications?
Yes, P6SMB160CAHE3/5B is AEC-Q101 qualified and carries the "HE3" suffix denoting RoHS-compliant and automotive-grade construction. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to meet automotive electronic module requirements. Its MSL Level 1 rating and 260 °C reflow compatibility further support use in automotive PCB assembly lines.
How does the bidirectional configuration of P6SMB160CAHE3/5B affect its PCB layout?
The bidirectional configuration of P6SMB160CAHE3/5B eliminates polarity marking and allows placement in either orientation on the PCB-no cathode band alignment is required. This simplifies layout, reduces assembly errors, and supports symmetric protection of differential or AC-coupled signals such as CAN FD or RS-422. Mounting uses standard 5.0 mm × 5.0 mm copper pads per datasheet recommendation to ensure thermal and surge performance.
What is the maximum reverse leakage current for P6SMB160CAHE3/5B at rated standoff voltage?
The P6SMB160CAHE3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at its rated standoff voltage (VWM) of 160 V and TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and minimizes standby power loss in battery-operated systems. Leakage remains below 5 μA up to +125 °C per thermal derating curves in the datasheet.
Does P6SMB160CAHE3/5B require special handling or baking prior to reflow soldering?
No, P6SMB160CAHE3/5B is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be processed using standard lead-free reflow profiles without pre-baking. Its moisture sensitivity is negligible due to the UL 94 V-0 molded package and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
