Product details
Overview
P6SMB150CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 150 V standoff voltage (VWM), 207 V maximum clamping voltage (VC) at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB150CAHE3_A/H datasheet, P6SMB150CAHE3_A/H pinout, P6SMB150CAHE3_A/H application, or P6SMB150CAHE3_A/H equivalent, key selection considerations include bidirectional transient suppression capability, AEC-Q101 qualification status, SMB (DO-214AA) package compatibility, and clamping performance under repetitive surge conditions.
Technical Context
The P6SMB150CAHE3_A/H operates as a bidirectional avalanche diode, symmetrically clamping voltage surges in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown behavior and low incremental surge resistance across temperature ranges from –65 °C to +150 °C.
It delivers 600 W peak pulse power per the 10/1000 μs standard waveform, with thermal resistance of 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead), enabling reliable operation on standard 0.2" × 0.2" copper pads without active cooling in most board-level protection applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 143–158 V at 1 mA test current - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 207 V at 2.9 A IPPM - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity under standardized surge waveform; supports IEC 61000-4-5 Level 3/4 compliance designs. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Minimal standby current leakage; preserves signal integrity and battery life in always-on circuits. |
| TJ max | +150 °C - Maximum junction temperature rating; enables use in under-hood automotive and high-temperature industrial environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same SMB package, identical VWM (128 V) and VC (207 V), but not AEC-Q101 qualified; commercial-grade only. | Lacks automotive qualification; suitable for industrial/commercial equipment where AEC-Q101 is not mandated. | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle traceability is not needed. |
| 1.5KE150CA | Through-hole DO-15 package; same 150 V standoff and 207 V clamping, but higher RθJA (70 °C/W vs. 100 °C/W) and larger footprint. | Requires PCB real estate and wave-solder process; less suitable for high-density SMT layouts. | Choose only if legacy through-hole design or manual repair constraints prohibit SMB surface-mount adoption. |
Compared with SMBJ150CA and 1.5KE150CA, P6SMB150CAHE3_A/H uniquely combines AEC-Q101 qualification, SMB footprint, and verified 600 W surge capability - making it the preferred choice for new automotive and space-constrained industrial designs requiring certified reliability.

FAQ
What does the "CA" suffix indicate in P6SMB150CAHE3_A/H?
The "CA" suffix denotes that P6SMB150CAHE3_A/H is a bidirectional Transient Voltage Suppressor. Unlike unidirectional variants (e.g., P6SMB150A), it provides symmetrical clamping in both voltage polarities without polarity marking - ideal for AC-coupled lines, differential buses like CAN, or any application where voltage reversal may occur during transients.
Is P6SMB150CAHE3_A/H suitable for automotive applications?
Yes, P6SMB150CAHE3_A/H is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay documentation. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC-Q101 Rev D, making it appropriate for under-hood and cabin electronics such as body control modules and ADAS sensor interfaces.
What is the maximum clamping voltage of P6SMB150CAHE3_A/H and under what test condition?
The maximum clamping voltage of P6SMB150CAHE3_A/H is 207 V, measured at a peak pulse current (IPPM) of 2.9 A using the standardized 10/1000 μs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the SMB (DO-214AA) package of P6SMB150CAHE3_A/H compare to larger TVS packages like DO-15?
The SMB package of P6SMB150CAHE3_A/H measures 4.57 mm × 3.94 mm × 2.20 mm - significantly smaller than DO-15 - enabling high-density PCB layouts. While both deliver 600 W peak power, the SMB's lower thermal resistance (RθJL = 20 °C/W) improves heat dissipation in compact assemblies compared to through-hole alternatives.
Does P6SMB150CAHE3_A/H require special PCB layout considerations?
Yes - Vishay specifies mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve rated 600 W pulse power. Narrow traces or insufficient copper area will increase thermal impedance and reduce effective surge handling capability, potentially causing premature failure during repetitive transients.
