Product details
Overview
P6SMB160A-M3/5B 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 219 V maximum clamping voltage (VC) at 2.7 A peak pulse current (IPPM), designed to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive power electronics.
For engineers reviewing the P6SMB160A-M3/5B datasheet, P6SMB160A-M3/5B pinout, P6SMB160A-M3/5B application, or P6SMB160A-M3/5B equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, 600 W peak pulse power handling under 10/1000 μs waveform, unidirectional polarity with cathode band marking, and halogen-free RoHS-compliant M3 suffix construction.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal bias it presents high impedance (>1 MΩ leakage at 136 V), but triggers avalanche conduction when reverse voltage exceeds VBR (152–168 V), limiting transient energy by diverting surge current away from downstream components. Its low incremental surge resistance ensures stable clamping performance across repetitive 0.01% duty cycle pulses.
The device uses glass-passivated silicon junction technology, enabling fast response time (<1 ns), compliance with J-STD-020 MSL Level 1 (260 °C reflow peak), and operation over -65 °C to +150 °C junction temperature range - critical for under-hood automotive and industrial motor drive environments where thermal cycling and humidity exposure occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before significant leakage; defines upper limit of normal circuit operation. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA test current - Voltage threshold at which avalanche conduction begins; determines minimum overvoltage protection trigger point. |
| VC (Clamping Voltage) | 219 V at 2.7 A IPPM - Maximum voltage seen by protected circuit during 10/1000 μs transient; must remain below downstream device's absolute max rating. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity under standardized 10/1000 μs waveform; enables suppression of high-energy transients like ISO 7637-2 pulse 5a. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Low leakage preserves system efficiency and prevents false triggering in high-impedance sensing circuits. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in engine control units and industrial inverters without derating at ambient ≤125 °C. |
| Package | SMB (DO-214AA) - Surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with automated pick-and-place and reflow soldering per J-STD-002. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 flammability rating, and cathode band marking on unidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Reverse voltage reference | Connected to ground or lower-potential rail in unidirectional configuration; establishes reference for clamping action. |
| Cathode | Reverse voltage input / Clamping output | Connected to protected line (e.g., power rail or signal trace); conducts surge current to anode when VREV > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against high-energy transients such as load dump and inductive kick in 24 V automotive systems. |
| Glass passivated chip junction | Ensures long-term reliability and stable electrical parameters under thermal stress and humidity exposure per AEC-Q101 requirements. |
| Halogen-free, RoHS-compliant (M3 suffix) | Meets environmental compliance mandates for industrial and automotive OEMs without compromising surge performance. |
| MSL Level 1 moisture sensitivity | Allows standard SMT reflow without baking; eliminates production delays and moisture-related delamination risk. |
| Low clamping ratio (VC/VBR ≈ 1.30) | Minimizes overvoltage overshoot during clamping, reducing stress on downstream MOSFET gate oxides and logic IC inputs. |
Applications
| Automotive Power Rail Protection | Industrial Motor Drive I/O Protection |

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 | Same VWM (136 V), higher VC (230 V), lower PPPM (400 W), SMA package (smaller thermal mass) | Less suitable for high-repetition surges due to lower power rating and reduced heatsinking capability | Select only if board space is constrained and surge duty cycle remains <0.005 % |
| 1.5SMC160A | Same VWM/VC specs, 1.5 kW PPPM, larger SMC (DO-214AB) package, higher IFSM (200 A) | Better suited for infrequent but extreme transients (e.g., direct lightning coupling) requiring higher single-pulse margin | Choose when PCB layout allows larger footprint and system-level testing demands >600 W margin |
Compared with SMAJ160A and 1.5SMC160A, P6SMB160A-M3/5B delivers optimal balance of 600 W pulse handling, SMB footprint compatibility, and halogen-free construction - making it preferred for volume automotive and industrial designs where manufacturability, compliance, and repeatable clamping performance are jointly prioritized.

FAQ
What is the clamping voltage of P6SMB160A-M3/5B at its rated peak pulse current?
The P6SMB160A-M3/5B has a maximum clamping voltage (VC) of 219 V when subjected to its specified peak pulse current (IPPM) of 2.7 A under a 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring compatibility with 200 V-rated MOSFETs or 250 V-rated capacitors downstream.
Is P6SMB160A-M3/5B suitable for automotive applications requiring AEC-Q101 qualification?
No - P6SMB160A-M3/5B carries the M3 suffix (halogen-free, RoHS-compliant commercial grade) but lacks AEC-Q101 qualification. For automotive use, specify P6SMB160AHM3_B/5B, which adds the "_B" revision code denoting AEC-Q101 qualification per Vishay's ordering table on page 3 of document 88370. The base P6SMB160A-M3/5B is rated for industrial and telecom applications only.
How does the SMB package of P6SMB160A-M3/5B compare to SMA or SMC in thermal performance?
The SMB (DO-214AA) package of P6SMB160A-M3/5B offers a thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), positioning it between SMA (higher RθJA) and SMC (lower RθJA). Its 5.59 mm × 4.06 mm footprint provides better power dissipation than SMA while maintaining compatibility with dense layouts - making P6SMB160A-M3/5B ideal for applications needing 600 W pulse handling without SMC's larger board area.
What is the reverse leakage current specification for P6SMB160A-M3/5B at its maximum standoff voltage?
At its maximum standoff voltage (VWM) of 136 V, the P6SMB160A-M3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C, as specified in Table 1 of Vishay document 88370. This ultra-low leakage ensures minimal power loss in always-on systems and avoids false triggering in high-impedance sensor bias networks - a key advantage over older TVS families with >5 μA leakage at similar voltages.
Can P6SMB160A-M3/5B be used in bidirectional configurations?
No - P6SMB160A-M3/5B is a unidirectional TVS diode, indicated by the "A" suffix (not "CA"). Bidirectional operation requires the CA variant (e.g., P6SMB160CA), which has symmetrical breakdown in both polarities. Using P6SMB160A-M3/5B in reverse-biased AC signal paths would result in forward conduction and failure; always verify polarity marking (cathode band) during placement.
