Product details
Overview
P6SMB150CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 150 V standoff voltage (VWM), 165 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to ≤207 V at 2.9 A peak pulse current and operates from −65 °C to +150 °C, targeting ESD and surge protection on automotive sensor signal lines.
For engineers reviewing the P6SMB150CAHE3_B/H datasheet, P6SMB150CAHE3_B/H pinout, P6SMB150CAHE3_B/H application, or P6SMB150CAHE3_B/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), clamping behavior under 10/1000 μs surges, and bidirectional polarity configuration - all critical for robust transient suppression in automotive-grade PCB designs.
Technical Context
This device implements a silicon avalanche diode structure with glass-passivated junction, enabling sub-nanosecond response to voltage transients. Its bidirectional symmetry ensures identical clamping performance in both polarities, with no cathode/anode marking required on the SMB package body.
Designed for automated SMT placement, it meets J-STD-020 MSL Level 1 (peak reflow 260 °C) and JESD201 Class 2 whisker resistance. The 600 W peak pulse rating applies under 0.01 % duty cycle conditions with derating above 25 °C ambient per Fig. 2 of the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 150 V - Maximum continuous reverse working voltage before conduction begins; defines operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 165–183 V at 1 mA - Guaranteed avalanche initiation range; ensures reliable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Maximum transient energy absorption capability under standardized 10/1000 μs waveform; defines surge survivability. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes. |
| TJ max | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs board-level copper pad design (0.2" × 0.2") for thermal management. |

IC Role / Device Role / Timing Role: Snubber-connected TVS across motor terminals to absorb inductive kickback during PWM switching. Use Value: Bidirectional operation accommodates reversal of motor polarity; 150 V VWM matches typical 24–36 V system rails with safety margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150CA | Same VWM (150 V), lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy surges; less suitable for automotive load dump where 600 W is mandated. | Select P6SMB150CAHE3_B/H when 600 W rating and AEC-Q101 qualification are required; SMAJ150CA only if space-constrained and surge energy <400 W. |
| SMCJ150CA | Same VWM (150 V), higher PPPM (1500 W), larger SMC package (DO-214AB), RθJA = 50 °C/W | Overqualified for many 600 W use cases; requires more PCB area and cost premium. | Choose P6SMB150CAHE3_B/H for optimal balance of 600 W capability, SMB footprint, and automotive qualification - SMCJ150CA only for extreme surge environments demanding >1 kW. |
Compared with SMAJ150CA and SMCJ150CA, P6SMB150CAHE3_B/H uniquely delivers AEC-Q101 qualification, 600 W pulse rating, and SMB package size in one solution - making it the preferred choice for space-limited automotive and industrial designs requiring certified reliability without over-engineering.

FAQ
What does the "CA" suffix indicate in P6SMB150CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning the P6SMB150CAHE3_B/H provides symmetrical transient suppression for both positive and negative voltage excursions, with identical VWM, VBR, and VC characteristics in either polarity. This eliminates the need for polarity-aware placement and simplifies layout for differential or AC-coupled signal lines.
Is P6SMB150CAHE3_B/H qualified for automotive use?
Yes, P6SMB150CAHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3" base suffix and "_B" revision code in the ordering information. It has undergone stress testing per AEC-Q101 standards including HTGB, TCT, and mechanical shock, making it suitable for under-hood and cabin electronics such as body control modules and ADAS sensors.
What is the maximum clamping voltage of P6SMB150CAHE3_B/H under surge conditions?
The maximum clamping voltage (VC) of P6SMB150CAHE3_B/H is 207 V, measured at a peak pulse current (IPPM) of 2.9 A using 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 transient events.
How does the SMB (DO-214AA) package of P6SMB150CAHE3_B/H compare thermally to larger packages?
The SMB package of P6SMB150CAHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. While higher than SMC (50 °C/W) or D2PAK (>30 °C/W), this value is optimized for compact layouts and remains sufficient for 600 W pulses at low duty cycles - validated in Vishay's Fig. 2 derating curves.
Can P6SMB150CAHE3_B/H replace unidirectional TVS diodes like P6SMB150AHE3_B/H?
No - P6SMB150CAHE3_B/H is strictly bidirectional and lacks cathode/anode polarity marking, whereas P6SMB150AHE3_B/H is unidirectional with defined cathode band. Substitution would compromise protection on DC-biased lines (e.g., power rails), where unidirectional devices block reverse leakage but allow forward conduction. Always match polarity type to circuit topology.
