Product details
Overview
P6SMB150CAHE3/5B 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), 207 V clamping voltage (VC) at 2.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects sensitive ICs, MOSFETs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB150CAHE3/5B datasheet, P6SMB150CAHE3/5B pinout, P6SMB150CAHE3/5B application, or P6SMB150CAHE3/5B equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 V stand-off rating, low incremental surge resistance, and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and long-term reliability under repetitive surge stress.
The device delivers 600 W peak pulse power handling per 10/1000 μs waveform at TA = 25 °C, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W, supporting operation up to TJ = +150 °C. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 150 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown) | 143–158 V at IT = 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping) | 207 V at IPPM = 2.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; limits stress on downstream components. |
| PPPM | 600 W - Surge energy absorption capacity per standardized waveform; enables robust protection against IEC 61000-4-5 level 4 threats. |
| ID (Leakage) | 1.0 μA max at VWM - Negligible standby current; avoids signal distortion or power loss in high-impedance circuits. |
| TJ max | +150 °C - Maximum junction temperature; supports extended operation in under-hood automotive or industrial enclosures. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (reverse bias) | One terminal of symmetrical avalanche junction; conducts during positive or negative overvoltage events. |
| Cathode | Transient current exit (reverse bias) | Second terminal of symmetrical junction; completes bidirectional conduction path with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses, or ungrounded interfaces without polarity concerns. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure field reliability. |
| 600 W peak pulse power | Supports compliance with IEC 61000-4-5 (10/1000 μs) surge immunity up to 4 kV in system-level testing. |
| Low clamping ratio (VC/VWM = 1.38) | Minimizes voltage overshoot during clamping, reducing stress on 150 V-rated downstream components. |
| MSL Level 1 rating | Permits unlimited floor life and reflow soldering at peak 260 °C without moisture-induced damage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150CA | Same VWM (150 V), VC = 243 V at 2.5 A; lower PPPM (600 W same), but higher clamping voltage (+17 %). | Less effective for 150 V-rated loads near absolute maximum ratings due to elevated VC. | Select P6SMB150CAHE3/5B when tighter clamping (207 V) is required to protect margin-constrained 150 V systems. |
| 1.5SMC150CA | Higher package thermal mass (SMC vs SMB); VC = 243 V at 2.5 A; same VWM but larger footprint and lower board density. | Suitable where PCB space allows and higher surge repetition rate is needed due to better heat dissipation. | Choose P6SMB150CAHE3/5B for space-constrained SMT designs requiring AEC-Q101 qualification and MSL Level 1 process compatibility. |
Compared with SMBJ150CA and 1.5SMC150CA, P6SMB150CAHE3/5B offers superior clamping performance (207 V vs ≥243 V), smaller SMB footprint, and verified AEC-Q101 qualification-making it optimal for automotive and high-density industrial PCBs where voltage margin and layout efficiency are critical.

FAQ
What is the clamping voltage of P6SMB150CAHE3/5B and how does it affect circuit protection?
The P6SMB150CAHE3/5B has a maximum clamping voltage (VC) of 207 V at 2.9 A peak pulse current (10/1000 μs waveform). This value defines the highest voltage imposed on the protected circuit during a surge event. Because VC is only 38 % above its 150 V stand-off rating, P6SMB150CAHE3/5B provides tight voltage limiting-critical for safeguarding 150 V-rated components such as certain MOSFETs, transceivers, and power management ICs without overstressing their absolute maximum ratings.
Is P6SMB150CAHE3/5B qualified for automotive use?
Yes, P6SMB150CAHE3/5B is AEC-Q101 qualified, as confirmed by the "HE3" suffix and Vishay documentation. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias (HTRB), and ESD-to meet automotive reliability standards. This qualification makes P6SMB150CAHE3/5B suitable for under-hood and cabin applications such as engine control units, battery management systems, and ADAS sensor interfaces.
What does the "CA" suffix mean in P6SMB150CAHE3/5B?
The "CA" suffix in P6SMB150CAHE3/5B denotes a bidirectional configuration, meaning the device functions identically in both polarities-clamping positive and negative transients without regard to orientation. Unlike unidirectional variants (e.g., P6SMB150A), P6SMB150CAHE3/5B has no cathode band marking and is used where AC signals, differential pairs, or floating grounds require symmetrical overvoltage protection.
What is the thermal resistance of P6SMB150CAHE3/5B and why does it matter?
P6SMB150CAHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead resistance (RθJL) of 20 °C/W. These values determine how effectively heat generated during surge events dissipates into the PCB and ambient environment. Lower RθJL supports short-duration pulse handling, while RθJA informs steady-state derating-especially important in enclosed industrial enclosures where ambient temperatures exceed 70 °C.
How does the SMB (DO-214AA) package of P6SMB150CAHE3/5B compare to larger TVS packages like SMC or SMA?
The SMB (DO-214AA) package of P6SMB150CAHE3/5B measures 4.57 mm × 3.94 mm × 2.20 mm-smaller than SMC (DO-214AB) and SMA (DO-214AC)-enabling higher board density and compatibility with fine-pitch automated placement. While SMC offers higher thermal mass for repetitive surges, P6SMB150CAHE3/5B's SMB footprint delivers optimal balance of surge capability (600 W), size, and manufacturability for space-constrained applications such as automotive ECUs and portable telecom gear.
