Product details
Overview
P6SMB160AHE3/5B 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 power rails and signal lines in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB160AHE3/5B datasheet, P6SMB160AHE3/5B pinout, P6SMB160AHE3/5B application, or P6SMB160AHE3/5B equivalent, this AEC-Q101 qualified TVS offers verified 600 W peak pulse power (10/1000 μs), low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability automotive ECUs, DC power inputs, and sensor interface protection where clamping accuracy and thermal robustness are design-critical.
Technical Context
This unidirectional TVS operates with a cathode-band polarity marking, exhibits 0.108 %/°C temperature coefficient of VBR, and delivers 219 V clamping at 2.7 A IPPM under standardized 10/1000 μs waveform conditions. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at 136 V) and fast response time (<1.0 ns).
Thermally, it features 20 °C/W junction-to-lead resistance and 100 °C/W junction-to-ambient resistance on recommended 5.0 mm × 5.0 mm copper pads. It is rated for -65 °C to +150 °C operating junction temperature and supports repetitive surge duty cycle up to 0.01 %.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 152–168 V at 1.0 mA IT - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 219 V at 2.7 A IPPM - Peak voltage seen by protected circuit during 600 W transient; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains high-energy surges without failure; validated per IEC 61000-4-5 Level 4 requirements. |
| ID (Reverse Leakage) | <1.0 μA at 136 V - Minimal standby power loss and signal integrity impact in high-impedance circuits. |

Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads; meets UL 94 V-0 flammability rating and J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line. | Defines polarity-sensitive placement - must be tied to ground or return path when protecting positive rail. |
| Cathode | Current exit terminal in forward bias; marked with band on device body. | Connected to protected line (e.g., 12 V supply); clamps transients to cathode potential during overvoltage events. |
Key Features

| MSL Level 1 (260 °C peak reflow) | Compatible with standard lead-free SMT assembly processes without pre-baking. |
| Glass-passivated junction | Ensures stable leakage current and long-term reliability under thermal cycling and humidity exposure. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Protection |
|---|---|
Use Scenario: Protects 12 V power input of BCM against load-dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and LDO input to clamp surges before regulation stage. Use Value: Limits transient voltage to ≤219 V, preventing damage to 36 V-rated input capacitors and enabling single-stage protection without series impedance. |
Use Scenario: Shields 24 V digital input channels of programmable logic controllers from field-wiring induced surges and ESD. IC Role / Device Role / Timing Role: Standoff-rated TVS on input terminal block, coordinated with series current-limiting resistor. Use Value: Clamps 1 kV/500 A surge (IEC 61000-4-5) within 1 ns, preserving signal integrity while meeting EN 61000-6-2 immunity requirements. |
| Telecom Power Supply Front-End | Automotive Sensor Signal Line Protection |
Use Scenario: Guards primary-side DC bus of telecom AC/DC converters against lightning-induced surges on AC mains input. IC Role / Device Role / Timing Role: Secondary-side TVS on bulk capacitor output, complementing MOV-based primary protection. Use Value: Provides precise 136 V standoff and low-leakage clamping to avoid false triggering during normal 120 VAC rectified ripple. |
Use Scenario: Safeguards LIN bus or analog sensor outputs (e.g., pressure, temperature) in engine bay against coupled transients. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed directly at connector interface, before ESD protection diode array. Use Value: Delivers sub-1 ns response and <1.0 μA leakage at 136 V, ensuring no interference with 12-bit ADC reference stability or LIN timing margins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/5B | Same VWM (136 V), but lower PPPM (400 W); SMB package identical; no AEC-Q101 qualification. | Suitable for commercial-grade industrial power supplies where automotive reliability is not required. | Select when cost sensitivity outweighs AEC-Q101 compliance and 600 W surge margin is non-critical. |
| 1.5SMC160A | Same electrical specs (VWM/VBR/VC), but SMC (DO-214AB) package - 2.6 mm wider, higher thermal mass. | Better thermal dissipation in high-ambient designs; requires larger PCB footprint and different pad layout. | Choose for high-power industrial systems needing enhanced thermal endurance, accepting larger board area. |
Compared with SMAJ160A-E3/5B and 1.5SMC160A, P6SMB160AHE3/5B uniquely combines AEC-Q101 qualification, SMB footprint compactness, and full 600 W surge capability - making it the optimal choice for space-constrained automotive modules requiring certified reliability.

FAQ
What is the clamping voltage of P6SMB160AHE3/5B at its rated peak pulse current?
The P6SMB160AHE3/5B has a maximum clamping voltage (VC) of 219 V at 2.7 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. The clamping performance is validated per JEDEC test methods and forms the basis for downstream component voltage derating.
Is P6SMB160AHE3/5B suitable for automotive applications?
Yes, P6SMB160AHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It undergoes rigorous stress testing including high-temperature operating life, temperature cycling, and ESD verification - making it approved for use in automotive body control modules, infotainment power supplies, and sensor interfaces where reliability under harsh environmental conditions is required.
What does the "5B" in P6SMB160AHE3/5B indicate?
The "5B" suffix denotes the packaging configuration: 13-inch diameter plastic tape and reel, containing 3200 units per reel. This format supports high-volume automated SMT placement and is compatible with standard pick-and-place equipment. The "HE3" portion confirms RoHS-compliant construction and AEC-Q101 qualification, while "5B" specifies logistics and handling details independent of electrical function.
How does P6SMB160AHE3/5B compare to bidirectional TVS diodes like P6SMB160CAHE3/5B?
P6SMB160AHE3/5B is unidirectional and intended for DC rail protection with defined polarity (cathode to protected line), whereas P6SMB160CAHE3/5B is bidirectional and used in AC or floating-signal applications. The unidirectional version offers lower leakage (<1.0 μA vs. up to 2.0 μA for bidirectional variants at same VWM) and is preferred for 12 V/24 V automotive power rails where polarity is fixed and leakage impacts sleep-mode current budgets.
What is the thermal resistance of P6SMB160AHE3/5B, and how does it affect PCB layout?
P6SMB160AHE3/5B has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W and junction-to-ambient (RθJA) of 100 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To maintain TJ ≤ 150 °C under 600 W pulses, designers must ensure adequate copper area and minimize trace length between device terminals and thermal planes - especially critical in automotive under-hood applications with ambient temperatures exceeding 105 °C.
