Product details
Overview
P6SMB150AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, with 150 V standoff voltage (VWM), 158 V maximum breakdown voltage (VBR), and 207 V clamping voltage (VC) at 2.9 A peak pulse current (IPPM). It delivers 600 W peak pulse power (10/1000 μs waveform) and is AEC-Q101 qualified for automotive-grade surge protection on power rails and signal lines.
For engineers reviewing the P6SMB150AHE3/52 datasheet, P6SMB150AHE3/52 pinout, P6SMB150AHE3/52 application, or P6SMB150AHE3/52 equivalent, this device is selected for high-reliability transient suppression where precise clamping, low leakage (<1.0 μA at VWM), and automotive qualification are required - especially in 12 V/24 V vehicle subsystems, industrial power inputs, and sensor interface protection.
Technical Context
The P6SMB150AHE3/52 uses a glass-passivated silicon junction optimized for fast response to ESD and lightning-induced transients. Its unidirectional polarity enables DC-biased rail protection with cathode-anode orientation, and its thermal resistance (RθJA = 100 °C/W) assumes mounting on 0.2" × 0.2" copper pads per terminal.
It operates across -65 °C to +150 °C junction temperature range, supports 100 A non-repetitive forward surge current (IFSM), and meets J-STD-020 MSL Level 1 with 260 °C reflow peak. The device exhibits a +0.108 %/°C temperature coefficient of VBR, ensuring predictable voltage drift under thermal stress.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150A-E3/52 | Same VWM/VBR/VC specs but lower PPPM (400 W), SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4. | Select only when board space is constrained and surge energy is ≤400 W; verify thermal derating at 125 °C ambient. |
| 1.5SMC150A | Same electrical specs but SMC (DO-214AB) package: larger footprint, lower RθJA (60 °C/W), higher IFSM (200 A). | Better thermal handling for high-duty-cycle surges; requires more PCB area and may not fit dense automotive layouts. | Prefer for industrial motor drives or power supplies needing enhanced surge endurance; verify layout clearance for SMC body. |
Compared with SMAJ150A-E3/52 and 1.5SMC150A, the P6SMB150AHE3/52 balances automotive qualification, 600 W robustness, and SMB footprint - making it optimal for space-constrained, high-reliability 12–48 V systems where AEC-Q101 compliance and thermal performance are jointly critical.

FAQ
What is the clamping voltage of the P6SMB150AHE3/52 at its rated peak pulse current?
The P6SMB150AHE3/52 has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (IPPM), measured using the standardized 10/1000 μs double-exponential waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB150AHE3/52 maintains this clamping performance with low incremental resistance, minimizing overshoot beyond 207 V.
Is the P6SMB150AHE3/52 suitable for automotive applications?
Yes, the P6SMB150AHE3/52 is AEC-Q101 qualified, as confirmed by its HE3 suffix and Vishay's documentation. It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD (HBM ≥ 8 kV), making it suitable for under-hood and cabin modules including body control units, infotainment power supplies, and ADAS camera interfaces. The P6SMB150AHE3/52 meets automotive reliability requirements without derating at 125 °C ambient.
What does the "HE3" suffix indicate in P6SMB150AHE3/52?
The "HE3" suffix in P6SMB150AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads meeting J-STD-002 solderability standards. It distinguishes this variant from commercial-grade E3 or M3 versions and confirms compliance with automotive stress test protocols. The P6SMB150AHE3/52 is manufactured to the same process controls and screening as other HE3-suffix parts in the P6SMB family.
How does the P6SMB150AHE3/52 compare to bidirectional TVS diodes in the same series?
The P6SMB150AHE3/52 is unidirectional and intended for DC-biased lines where polarity is fixed (e.g., +12 V rail to ground). Bidirectional variants like P6SMB150CA have symmetric clamping in both directions and are used on AC-coupled or floating lines (e.g., RS-485, CAN bus). The P6SMB150AHE3/52 offers tighter leakage (<1.0 μA) and higher IFSM (100 A) than its bidirectional counterpart, but cannot protect AC signals without external biasing.
What is the thermal resistance of the P6SMB150AHE3/52, and how does it affect layout design?
The P6SMB150AHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes no internal layer copper and standard FR-4. To maintain TJ ≤ 150 °C at full 5.0 W steady-state dissipation, designers must ensure adequate pad area and consider airflow or adjacent thermal vias. The P6SMB150AHE3/52 thermal performance is validated per JEDEC standards and referenced in Vishay Document 88370.
