Product details
Overview
P6SMB150AHE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 150 V standoff voltage (VWM), 179 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 capability with a 10/1000 μs waveform.
For engineers reviewing the P6SMB150AHE3_A/H datasheet, P6SMB150AHE3_A/H pinout, P6SMB150AHE3_A/H application, or P6SMB150AHE3_A/H equivalent, this device is selected for high-reliability transient suppression in automotive power rails, industrial sensor interfaces, and telecom line protection where AEC-Q101 qualification, low incremental surge resistance, and fast response time are critical.
Technical Context
The P6SMB150AHE3_A/H operates as a unidirectional avalanche diode, clamping transients above its breakdown threshold by entering avalanche conduction. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<1.0 μA at 128 V), while the SMB package supports automated placement and meets MSL Level 1 reflow requirements (260 °C peak).
Thermal performance is defined by RθJA = 100 °C/W and RθJL = 20 °C/W, enabling operation up to +150 °C junction temperature. The device sustains repetitive 10/1000 μs pulses at 0.01% duty cycle and handles non-repetitive 8.3 ms half-sine surges up to 100 A (IFSM), making it suitable for inductive load switching and lightning-induced surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 143–158 V at 1.0 mA - Precise avalanche initiation range ensuring predictable turn-on during transients |
| VC (Clamping Voltage) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit under 600 W surge, limiting stress on downstream ICs |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability for 10/1000 μs waveform, critical for IEC 61000-4-5 compliance |
| ID (Reverse Leakage) | <1.0 μA at 128 V - Minimal standby power loss and signal integrity impact in high-impedance circuits |
| TJ max. | +150 °C - Enables deployment in under-hood automotive and industrial environments without derating |

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-E3/5B | Same VWM (150 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA) | Limited to lower-energy transients; not AEC-Q101 qualified | Select when board space is constrained and surge energy is ≤400 W |
| 1.5KE150A | Through-hole DO-201 package; identical VWM/VBR/VC specs; same 600 W rating | Requires wave soldering or hand assembly; unsuitable for fully SMT lines | Choose for legacy designs or prototyping where manual assembly is acceptable |
Compared with SMAJ150A-E3/5B and 1.5KE150A, the P6SMB150AHE3_A/H delivers AEC-Q101 qualification, SMB package compatibility with high-speed pick-and-place, and optimized thermal resistance (RθJL = 20 °C/W) for sustained surge handling in compact automotive and industrial PCB layouts.

FAQ
What is the clamping voltage of P6SMB150AHE3_A/H at its rated peak pulse current?
The P6SMB150AHE3_A/H has a maximum clamping voltage (VC) of 207 V at a peak pulse current (IPPM) of 2.9 A, measured using the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on the protected circuit during a 600 W transient event and is critical for ensuring downstream components remain within their absolute maximum ratings. The P6SMB150AHE3_A/H maintains this clamping performance across its specified operating temperature range.
Is P6SMB150AHE3_A/H qualified for automotive applications?
Yes, the P6SMB150AHE3_A/H is AEC-Q101 qualified, as indicated by the "HE3" suffix in its ordering code. This qualification confirms successful completion of stress tests including high-temperature reverse bias (HTRB), temperature cycling, and electrostatic discharge (ESD), making the P6SMB150AHE3_A/H suitable for use in automotive powertrain, body control, and infotainment systems where zero-defect reliability is required.
What does the "_A/H" suffix in P6SMB150AHE3_A/H signify?
The "_A/H" suffix in P6SMB150AHE3_A/H denotes packaging configuration: "A" indicates the base device is unidirectional, and "H" specifies 7-inch plastic tape-and-reel delivery (750 units per reel). The "HE3" portion confirms RoHS-compliance and AEC-Q101 qualification. This full suffix ensures precise identification of electrical type, qualification level, and logistics format for procurement and assembly planning of the P6SMB150AHE3_A/H.
How does the thermal resistance of P6SMB150AHE3_A/H affect its surge handling capability?
The P6SMB150AHE3_A/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, which enables efficient heat transfer from the silicon die to the PCB copper pads during transient events. This low RθJL allows the P6SMB150AHE3_A/H to sustain repetitive 600 W surges without excessive junction temperature rise, especially when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal-directly supporting reliable operation in thermally demanding automotive and industrial environments.
Can P6SMB150AHE3_A/H be used in bidirectional protection circuits?
No, the P6SMB150AHE3_A/H is a unidirectional TVS diode, as confirmed by its "A" suffix and cathode band marking. For bidirectional protection, Vishay offers the P6SMB150CA variant (with "CA" suffix), which provides symmetrical clamping in both polarities. Using the unidirectional P6SMB150AHE3_A/H in a bidirectional application would result in forward conduction and potential failure during negative transients-so correct polarity orientation and device selection are essential for the P6SMB150AHE3_A/H.
