Product details
Overview
P6SMB150CAHM3_A/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal and power lines. It features a 150 V standoff voltage (VWM), 165 V minimum breakdown voltage (VBR), 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, sensor interfaces, and telecom line drivers against ESD and inductive switching surges.
For engineers reviewing the P6SMB150CAHM3_A/I datasheet, P6SMB150CAHM3_A/I pinout, P6SMB150CAHM3_A/I application, or P6SMB150CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), low leakage (<1.0 μA at VWM), and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped surge protector with symmetrical avalanche behavior in both directions, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1.0 ns), while the low incremental surge resistance supports effective energy diversion during repetitive transients.
The P6SMB150CAHM3_A/I is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow 260 °C), with halogen-free, RoHS-compliant construction and matte tin-plated terminals solderable per J-STD-002. It is qualified to AEC-Q101 for automotive applications and specified for use with 0.2" × 0.2" copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 150 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 165–185 V at 1 mA - Confirmed avalanche initiation range; ensures reliable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity under standardized 10/1000 μs waveform; enables robust protection against IEC 61000-4-5 surges. |
| ID (Reverse Leakage) | <1.0 μA at 150 V - Minimal standby current; avoids signal distortion or power loss in high-impedance circuits. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; requires adequate PCB copper area for sustained 5.0 W dissipation. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |

Use Scenario: Safeguarding RS-485 transceivers in factory automation PLCs exposed to motor drive noise and ground bounce. IC Role / Device Role / Timing Role: Differential-line TVS connected across A/B lines and to ground to suppress common-mode and differential-mode transients. Use Value: Maintains data integrity under IEC 61000-4-4 EFT bursts (4 kV) and prevents communication lockup in noisy industrial environments. |
| Telecom Line Card Surge Suppression | Consumer USB Port ESD Protection |
Use Scenario: Front-end protection of xDSL or POTS line interface ICs in DSLAMs and VoIP gateways subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Primary clamping device on tip/ring lines, coordinated with gas discharge tubes for staged protection. Use Value: Limits induced surge voltage to <210 V, ensuring survival of line driver amplifiers rated for 220 V absolute maximum. |
Use Scenario: Secondary-level ESD protection on USB 2.0 D+/D− lines in set-top boxes and smart displays. IC Role / Device Role / Timing Role: Fast-response TVS placed after series impedance to absorb ±15 kV contact discharge per IEC 61000-4-2. Use Value: Keeps junction capacitance low (<100 pF at 0 V) to avoid signal integrity degradation at 480 Mbps full-speed operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same VWM/VBR/VC ratings and SMB package, but not AEC-Q101 qualified; RθJA = 100 °C/W identical. | Commercial-grade only; unsuitable for automotive production where AEC-Q101 is mandated. | Select SMBJ150CA only for cost-sensitive industrial or consumer designs without automotive qualification requirements. |
| 1.5SMC150CA | Higher package thermal mass (SMC/DO-214AB); same electrical specs but RθJA = 60 °C/W; 1.5 kW PPPM rating. | Used where higher single-pulse energy handling is needed, but requires larger PCB footprint and different pad layout. | Choose 1.5SMC150CA when protecting high-energy circuits like PoE injectors, accepting larger board area and rework complexity. |
Compared with SMBJ150CA and 1.5SMC150CA, the P6SMB150CAHM3_A/I uniquely combines AEC-Q101 qualification, halogen-free compliance, and SMB footprint - making it the only drop-in solution for space-constrained automotive modules requiring zero layout change and certified reliability.

FAQ
What is the clamping voltage of P6SMB150CAHM3_A/I at its rated peak pulse current?
The P6SMB150CAHM3_A/I has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during surge events and is confirmed in Vishay's datasheet revision 09-Jan-2024, page 2. The P6SMB150CAHM3_A/I maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C).
Is P6SMB150CAHM3_A/I suitable for automotive applications?
Yes, the P6SMB150CAHM3_A/I is AEC-Q101 qualified, as indicated by the "HM3" and "_A/I" suffixes in its ordering code - confirming compliance with stress tests including temperature cycling, high-temperature reverse bias, and ESD. It is explicitly intended for automotive use cases such as sensor interface protection and infotainment power rail conditioning, and the P6SMB150CAHM3_A/I meets MSL Level 1 for lead-free reflow compatibility.
How does the bidirectional configuration of P6SMB150CAHM3_A/I affect PCB layout?
The P6SMB150CAHM3_A/I has no polarity marking and functions identically in either orientation, simplifying PCB layout for AC-coupled or differential signal paths like RS-485 or CAN. Unlike unidirectional TVS diodes, the P6SMB150CAHM3_A/I eliminates orientation verification during placement and allows symmetric routing - reducing assembly errors and enabling direct replacement in existing bidirectional protection footprints such as SMBJ150CA.
What is the maximum steady-state power dissipation for P6SMB150CAHM3_A/I?
The P6SMB150CAHM3_A/I has a maximum steady-state power dissipation (PD) of 5.0 W at TA = 50 °C on an infinite heatsink, with a typical thermal resistance of 100 °C/W junction-to-ambient. In real-world PCB conditions using Vishay's recommended 0.2" × 0.2" copper pads per terminal, derating applies above 25 °C ambient - the P6SMB150CAHM3_A/I must be thermally modeled to ensure TJ remains ≤150 °C under continuous leakage or bias conditions.
Does P6SMB150CAHM3_A/I meet RoHS and halogen-free requirements?
Yes, the "HM3" suffix in P6SMB150CAHM3_A/I denotes halogen-free, RoHS-compliant construction per EU Directive 2011/65/EU and Vishay document 99912. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated per J-STD-002. This makes the P6SMB150CAHM3_A/I compliant for export to EU, China, and other regulated markets requiring substance restrictions.
