Product details
Overview
P6SMB160CAHM3_B/H 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 clamps transients to ≤219 V at 2.7 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB160CAHM3_B/H datasheet, P6SMB160CAHM3_B/H pinout, P6SMB160CAHM3_B/H application, or P6SMB160CAHM3_B/H equivalent, key selection criteria include bidirectional clamping capability, 150 °C max junction temperature, MSL Level 1 moisture sensitivity, halogen-free RoHS compliance, and suitability for I/O line and power rail surge suppression in harsh environments.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal lines without polarity concerns. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns) to transient events such as ESD, lightning-induced surges, and inductive switching spikes.
The device uses a low-inductance SMB package with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, and achieves thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. It meets AEC-Q101 stress testing requirements for automotive underhood and infotainment applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 136 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 152–168 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 219 V at IPPM = 2.7 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000 μs waveform; enables robust surge handling. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | 150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and industrial ambient conditions. |
| Package | SMB (DO-214AA) - Surface-mount footprint with 3.94 mm × 2.20 mm body; compatible with automated pick-and-place and reflow. |

Applications
| Automotive Sensor Interface Protection | Industrial PLC I/O Module Protection |
|---|---|
Use Scenario: Protecting CAN, LIN, or analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surge energy before reaching signal conditioning ICs. Use Value: Maintains signal integrity under ±100 V transients while adding <0.5 pF capacitance-no data rate degradation on 1 Mbps CAN bus. |
Use Scenario: Safeguarding 24 V DC digital input channels in programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary overvoltage protection stage ahead of optocoupler or Schmitt trigger input circuitry. Use Value: Clamps 1 kV/500 A surge (per IEC 61000-4-5) to <220 V within nanoseconds, preventing latch-up or permanent damage to input buffers. |
| Telecom Line Card Surge Suppression | Consumer Appliance Motor Control Board |
Use Scenario: Secondary protection on Ethernet PHY or RS-485 transceiver lines in network edge equipment subjected to induced lightning surges. IC Role / Device Role / Timing Role: Fast-response TVS paired with GDT or polymer PTC for coordinated multi-stage surge management. Use Value: Limits transient overshoot to <219 V at 2.7 A, preserving transceiver ESD immunity margins and meeting GR-1089-CORE Level 4 requirements. |
Use Scenario: Input rail protection on BLDC motor driver boards in washing machines or HVAC systems where inductive kickback exceeds 200 V. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor to absorb stored inductive energy during MOSFET turn-off. Use Value: Absorbs 600 W peak pulse without thermal runaway, enabling compact layout with no heatsink-reducing BOM count vs. MOV-based solutions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160CA | Same VWM (136 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA). | Limited to lower-energy surges; less suitable for automotive load dump or industrial 24 V rail protection. | Select when space-constrained layouts prioritize size over surge margin, and peak currents remain <1.8 A. |
| SMCJ160CA | Same VWM (136 V), higher PPPM (1500 W), larger SMC package (DO-214AB), higher thermal mass. | Better suited for high-repetition-rate surges and sustained power dissipation in motor drive gate drivers. | Choose when system-level testing reveals >600 W surge exposure or when board layout allows larger 7.11 mm × 6.22 mm footprint. |
Compared with P6SMB160CAHM3_B/H, SMAJ160CA trades surge capacity for compactness, while SMCJ160CA delivers higher power handling at the cost of PCB area-making P6SMB160CAHM3_B/H the optimal balance of automotive qualification, SMB compatibility, and 600 W robustness for mid-tier industrial and automotive modules.

FAQ
What does the "CA" suffix indicate in P6SMB160CAHM3_B/H?
The "CA" suffix denotes a bidirectional configuration, meaning the P6SMB160CAHM3_B/H provides symmetrical clamping in both forward and reverse directions-ideal for protecting AC-coupled signals, differential buses like RS-485, or ungrounded power rails where polarity cannot be guaranteed.
Is P6SMB160CAHM3_B/H suitable for automotive applications?
Yes, P6SMB160CAHM3_B/H is AEC-Q101 qualified (indicated by the "_B/H" automotive ordering code), tested for temperature cycling, humidity bias, and mechanical shock. It is specified for under-hood and cabin applications including body control modules, sensor interfaces, and infotainment power supplies.
How does the SMB package of P6SMB160CAHM3_B/H compare to SMA or SMC packages?
The SMB (DO-214AA) package of P6SMB160CAHM3_B/H offers a 3.94 mm × 2.20 mm footprint-larger than SMA but smaller than SMC-delivering 600 W pulse power with moderate thermal resistance (RθJA = 100 °C/W). It balances surge capability, PCB area, and manufacturability better than SMA for mid-power applications and avoids the layout overhead of SMC.
What is the maximum clamping voltage of P6SMB160CAHM3_B/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB160CAHM3_B/H is 219 V at a peak pulse current (IPPM) of 2.7 A using the 10/1000 μs waveform. This value is measured and guaranteed per Vishay's datasheet (Document Number: 88370, Rev. 09-Jan-2024), ensuring predictable protection margin for downstream components.
Does P6SMB160CAHM3_B/H require special handling during PCB assembly?
No special handling is required: P6SMB160CAHM3_B/H is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/85 % RH and can be processed through standard lead-free reflow profiles without pre-baking. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102 solderability standards.
