Product details
Overview
P6SMB160A-E3/5B 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 600 W peak pulse power (10/1000 μs). It clamps transients to 219 V at 2.7 A peak pulse current and is RoHS-compliant for commercial-grade protection of DC power rails and signal lines in industrial sensor interfaces.
For engineers reviewing the P6SMB160A-E3/5B datasheet, P6SMB160A-E3/5B pinout, P6SMB160A-E3/5B application, or P6SMB160A-E3/5B equivalent, key selection criteria include unidirectional polarity, 136 V maximum reverse leakage at VWM, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, responding within picoseconds to voltage surges exceeding its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping performance across repetitive 0.01% duty-cycle transients.
The device is optimized for unidirectional DC line protection: cathode-banded polarity enables integration into positive-rail configurations without reverse conduction risk. Thermal derating follows a defined curve-junction temperature must remain ≤150 °C, with RθJA = 100 °C/W under standard PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above normal operating voltage |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected IC during 10/1000 μs transient; determines safe margin for downstream components |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized surge waveform; validates robustness against IEC 61000-4-5 Level 4 threats |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Minimal standby current draw; critical for low-power battery-backed systems |
| TJ max | 150 °C - Absolute maximum junction temperature; constrains thermal design when mounted on 5.0 mm × 5.0 mm pads |
| RθJA | 100 °C/W - Thermal resistance defining temperature rise per watt dissipated; used to calculate safe power derating above 25 °C ambient |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Cathode indicated by band; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when voltage exceeds VBR |
| Anode (unbanded end) | Reference node | Typically tied to system ground or common return; completes clamping path during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Validates compliance with IEC 61000-4-5 surge immunity requirements for industrial equipment |
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage parameters across temperature and humidity stress |
| MSL Level 1 (260 °C reflow) | Supports single-pass lead-free soldering without popcorn effect or delamination |
| RoHS-compliant, commercial grade (E3 suffix) | Meets EU Directive 2011/65/EU; suitable for non-automotive production with full traceability |
| Low profile SMB package | Enables high-density PCB layouts while maintaining 5.0 mm × 5.0 mm thermal pad area for effective heat dissipation |
Applications
| Industrial Sensor Interface Protection | DC Power Rail Clamping |

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/VBR/VC ratings but SMA package (DO-214AC); 130 °C/W RθJA vs. 100 °C/W | Lower power density handling due to higher thermal resistance; requires larger pad area for equivalent thermal performance | Select SMAJ160A only if legacy SMA footprint is fixed and thermal margin allows 30% lower power derating |
| 1.5SMC160A | Same electrical specs but SMC (DO-214AB) package; 1.5 kW peak power rating but identical 600 W test condition | Physically larger footprint (7.1 mm × 6.2 mm vs. 4.57 mm × 3.94 mm) limits use in space-constrained designs | Choose 1.5SMC160A when board layout permits larger package and higher surge margin is required beyond standard 600 W test |
Compared with P6SMB160A-E3/5B, SMAJ160A offers identical clamping performance but reduced thermal efficiency in compact layouts, while 1.5SMC160A provides mechanical robustness and higher surge headroom at the cost of PCB area-making P6SMB160A-E3/5B optimal for high-density industrial SMT assemblies requiring precise 136 V standoff control.

FAQ
What is the clamping voltage of the P6SMB160A-E3/5B under a 10/1000 μs surge?
The P6SMB160A-E3/5B clamps to a maximum of 219 V when subjected to its rated peak pulse current of 2.7 A under the standardized 10/1000 μs waveform. This value is measured at the device terminals with specified PCB mounting conditions (0.2" × 0.2" copper pads), and it defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB160A-E3/5B maintains this clamping performance across its operational temperature range and after repeated surge exposure.
Is the P6SMB160A-E3/5B suitable for automotive applications?
The base P6SMB160A-E3/5B is RoHS-compliant and qualified for commercial-grade use, not automotive. However, Vishay offers the AEC-Q101-qualified variant P6SMB160AHE3_B (with "_B" suffix), which shares identical electrical characteristics-including 136 V VWM, 152–168 V VBR, and 219 V VC-but undergoes additional stress testing for automotive environments. The P6SMB160A-E3/5B itself is not rated for automotive use unless explicitly ordered with HE3 or HM3 suffixes and revision code.
How does the P6SMB160A-E3/5B differ from bidirectional TVS diodes like P6SMB160CA?
The P6SMB160A-E3/5B is unidirectional and features a cathode band for polarity-sensitive placement, conducting only during positive transients relative to ground. In contrast, P6SMB160CA is bidirectional with no polarity marking and suppresses surges of either polarity-making it suitable for AC lines or differential signal pairs. Both share identical VWM (136 V), VBR (152–168 V), and VC (219 V), but the P6SMB160A-E3/5B cannot replace P6SMB160CA in AC-coupled or floating applications without circuit redesign.
What is the maximum reverse leakage current for the P6SMB160A-E3/5B at its standoff voltage?
The P6SMB160A-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA when biased at its rated standoff voltage of 136 V, measured at 25 °C ambient. This ultra-low leakage preserves system efficiency in always-on or battery-powered applications and avoids false triggering in high-impedance sensing circuits. The P6SMB160A-E3/5B maintains leakage below 5.0 μA up to 125 °C, supporting operation in thermally demanding enclosures.
Can the P6SMB160A-E3/5B be used in parallel to increase surge current handling?
No-parallel connection of P6SMB160A-E3/5B devices is not recommended due to parameter mismatch (VBR tolerance ±5%) causing uneven current sharing and potential thermal runaway. For higher IPPM requirements, select a single higher-rated device such as P6SMB200A (274 V VC) or use a TVS array with matched characteristics. The P6SMB160A-E3/5B is characterized and tested as a standalone unit; its 2.7 A IPPM rating assumes monolithic operation under defined thermal conditions.
