Product details
Overview
P6SMB160A-M3/52 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 to protect MOSFETs, ICs, and sensor signal lines in industrial power supplies and automotive control modules.
For engineers reviewing the P6SMB160A-M3/52 datasheet, P6SMB160A-M3/52 pinout, P6SMB160A-M3/52 application, or P6SMB160A-M3/52 equivalent, key selection criteria include unidirectional polarity, 136 V maximum reverse leakage at VWM, halogen-free RoHS compliance (M3 suffix), MSL Level 1 rating, and AEC-Q101 qualification availability via HM3 variant.
Technical Context
This TVS diode operates as a clamping device with fast response time and low incremental surge resistance, enabling effective suppression of inductive switching spikes and lightning-induced surges on DC power rails and low-speed signal paths. Its glass-passivated junction ensures stable performance under repetitive transient stress.
The device is designed for surface-mount assembly on 0.2" × 0.2" copper pads per terminal, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead). It supports continuous power dissipation up to 5.0 W at 50 °C ambient and withstands 100 A non-repetitive forward surge current (8.3 ms half-sine).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 136 V - Maximum steady-state reverse voltage before conduction begins; defines safe operating margin below clamping threshold |
| VBR (min) | 152 V - Minimum breakdown voltage at 1 mA test current; guarantees reliable turn-on above system operating voltage |
| VC @ IPPM | 219 V - Clamping voltage at 2.7 A peak pulse current; determines maximum voltage seen by protected circuit during surge |
| IPPM | 2.7 A - Peak pulse current supported under 10/1000 μs waveform; defines surge energy handling capability |
| PPPM | 600 W - Peak pulse power rating; enables protection against high-energy transients like ISO 7637-2 Load Dump or IEC 61000-4-5 |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design limits for PCB layout and power derating |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint and 2.20 mm height; compatible with automated pick-and-place |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Dimensions: 5.59 mm × 4.06 mm × 2.20 mm. Mounting requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal per Vishay specification.

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), identical SMB package, but lower PPPM (400 W) and higher VC (259 V at 2.1 A) | Limited to lower-energy transients; not suitable for ISO 7637-2 Pulse 5a/b or high-duty-cycle industrial environments | Select when cost sensitivity outweighs peak surge margin and board space allows parallel devices for power scaling |
| 1.5SMC160A | Higher package thermal mass (SMC), same VWM/VBR, but larger footprint (7.11 mm × 6.22 mm) and 1.5 kW PPPM rating | Used where PCB layout permits larger SMC package and higher sustained surge energy must be absorbed | Choose for legacy designs requiring drop-in replacement in SMC footprints or where 1.5 kW pulse handling is mandated |
Compared with SMAJ160A and 1.5SMC160A, the P6SMB160A-M3/52 delivers optimal balance of 600 W surge capacity, compact SMB footprint, and halogen-free compliance-making it preferred for space-constrained, high-volume industrial and automotive applications requiring validated MSL Level 1 process compatibility.

FAQ
What is the maximum clamping voltage of the P6SMB160A-M3/52 under standard test conditions?
The P6SMB160A-M3/52 has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM) using 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. The P6SMB160A-M3/52 maintains this clamping performance across its specified operating temperature range and after repeated surge exposure.
Does the P6SMB160A-M3/52 meet automotive qualification standards?
The P6SMB160A-M3/52 itself is a commercial-grade halogen-free part; however, the P6SMB160AHM3_D/H variant is AEC-Q101 qualified for automotive use. The P6SMB160A-M3/52 shares identical electrical characteristics and SMB packaging but lacks the extended reliability testing required for automotive deployment. Engineers selecting for automotive applications should specify the HM3 suffix version to ensure qualification compliance.
How does the M3 suffix affect the P6SMB160A-M3/52's environmental compliance and processing?
The M3 suffix on the P6SMB160A-M3/52 indicates halogen-free, RoHS-compliant construction with matte tin-plated leads that meet J-STD-002 and JESD 22-B102 solderability standards. It also satisfies JESD 201 Class 2 whisker resistance and MSL Level 1 rating for 260 °C lead-free reflow-enabling direct integration into high-reliability commercial and industrial assemblies without special handling or baking.
Can the P6SMB160A-M3/52 be used in bidirectional protection circuits?
No-the P6SMB160A-M3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional protection, Vishay offers the P6SMB160CA variant (with CA suffix), which provides symmetrical clamping in both polarities. Using the P6SMB160A-M3/52 in bidirectional configurations risks failure during negative transients due to lack of reverse conduction capability.
What is the thermal resistance profile of the P6SMB160A-M3/52, and how does it impact PCB layout?
The P6SMB160A-M3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W when mounted on 0.2" × 0.2" copper pads per terminal. To maintain safe operation at full 5.0 W continuous dissipation, PCB layout must provide adequate copper area and avoid thermal bottlenecks near the SMB footprint. The P6SMB160A-M3/52 thermal performance is validated only with this pad configuration.
