Product details
Overview
P6SMB150AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. 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 (PPPM) with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB150AHE3_B/I datasheet, P6SMB150AHE3_B/I pinout, P6SMB150AHE3_B/I application, or P6SMB150AHE3_B/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–65 °C to +150 °C), and RoHS-compliant matte tin-plated terminals - all critical for automotive-grade surge protection design validation.
Technical Context
This unidirectional TVS diode operates by avalanche breakdown to limit transient overvoltages before they damage downstream circuitry. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM), while low incremental surge resistance enables rapid energy absorption during ESD or inductive switching events.
The device meets J-STD-020 MSL Level 1 (260 °C peak reflow), supports automated SMT placement, and is qualified to AEC-Q101 for automotive applications. Its SMB package provides mechanical robustness and thermal dissipation suitable for board-level protection without heatsinking under defined pad layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 128 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 143–158 V at 1.0 mA test current - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 207 V at 2.9 A IPPM - 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; validates suitability for IEC 61000-4-5 Level 3/4 surges. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Minimal standby current; avoids unnecessary power loss or false triggering in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature; sets thermal derating limits for sustained operation in enclosed environments. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; used to calculate temperature rise under DC or repetitive pulse conditions. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. Cathode indicated by band marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected line's lower-potential side (e.g., ground or return path). | Provides reference point for clamping action; must be routed with low-inductance trace to minimize overshoot during fast transients. |
| Cathode | Current exit terminal in forward bias; connected to protected line's higher-potential side (e.g., VBUS or signal rail). | Acts as clamping node - voltage at cathode is limited to VC during surge; polarity marking ensures correct PCB orientation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive use per stress test requirements - enables deployment in engine control units, ADAS sensors, and infotainment power rails. |
| Glass passivated junction | Stable VBR and low ID over temperature and lifetime - eliminates parameter drift in harsh thermal cycling environments. |
| 600 W peak pulse rating | Handles IEC 61000-4-5 combination wave surges up to 4 kV (open-circuit)/2 kA (short-circuit) without degradation. |
| MSL Level 1 moisture sensitivity | Zero bake requirement before reflow - simplifies manufacturing flow and reduces risk of popcorning during assembly. |

FAQ
What is the clamping voltage of P6SMB150AHE3_B/I at its rated peak pulse current?
The P6SMB150AHE3_B/I has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88370 and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is P6SMB150AHE3_B/I qualified for automotive applications?
Yes, P6SMB150AHE3_B/I is AEC-Q101 qualified, as confirmed by the "_B" suffix in its ordering code and documented in Vishay's P6SMB series datasheet revision 09-Jan-2024. This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD - validating its use in engine control modules, body electronics, and ADAS sensor power domains.
What does the "HE3_B/I" suffix mean in P6SMB150AHE3_B/I?
In P6SMB150AHE3_B/I, "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction; "_B" indicates AEC-Q101 qualification level for the 6.8 V to 220 V voltage range; "/I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel - per Vishay's Ordering Information table on page 3 of document 88370.
Can P6SMB150AHE3_B/I be used in bidirectional configurations?
No, P6SMB150AHE3_B/I is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA") and absence of bidirectional VBR/VWM ranges in its electrical characteristics table. Bidirectional variants like P6SMB150CA exist separately - using P6SMB150AHE3_B/I in reverse-biased AC applications would result in unintended conduction and failure.
