Product details
Overview
P6SMB10CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 41.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial and automotive electronics.
For engineers reviewing the P6SMB10CAHE3/52 datasheet, P6SMB10CAHE3/52 pinout, P6SMB10CAHE3/52 application, or P6SMB10CAHE3/52 equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The P6SMB10CAHE3/52 operates as a bidirectional avalanche diode, providing symmetrical clamping in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns) to transient events such as ESD, lightning-induced surges, and inductive switching spikes.
It is rated for 600 W peak pulse power under 10/1000 μs waveform with 0.01% duty cycle, derated above 25 °C per thermal curve Fig. 2, and exhibits a typical junction-to-ambient thermal resistance of 100 °C/W when mounted on 0.2" × 0.2" copper pads - critical for sustained surge handling in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 10 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown) | 10.5 V min / 11.6 V max at 1 mA - Ensures reliable, repeatable avalanche initiation across production lots. |
| VC (Clamping) | 14.5 V max at 41.4 A IPPM - Limits downstream voltage stress during worst-case 10/1000 μs surge. |
| PPPM | 600 W - Peak transient energy absorption capacity; enables protection against IEC 61000-4-5 Level 4 surges. |
| ID (Leakage) | 10 μA max at 10 V - Low leakage preserves signal integrity and minimizes standby power loss. |
| TJ max | 150 °C - Supports operation in under-hood automotive and high-temperature industrial environments. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive polarity) | One terminal of symmetrical avalanche junction; connects to protected line without polarity constraint. |

Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector or IC input pins to shunt surge energy before it reaches sensitive circuitry. Use Value: Prevents latch-up or permanent damage to microcontrollers and transceivers while maintaining signal fidelity during normal operation due to low 10 μA leakage. |
Use Scenario: Shielding digital and analog I/O channels in programmable logic controllers exposed to relay coil flyback and motor drive noise. IC Role / Device Role / Timing Role: Primary transient suppressor on field-side signal traces, coordinated with series impedance for IEC 61000-4-4 EFT filtering. Use Value: Enables robust 600 W surge handling in space-constrained SMB footprint, eliminating need for larger DO-15 or SMA alternatives. |
| Telecom Line Interface | Consumer Power Adapter Input |
Use Scenario: Safeguarding Ethernet PHYs, RS-485 transceivers, and PoE injectors against induced lightning surges on outdoor cabling. IC Role / Device Role / Timing Role: First-line clamping device on differential pairs or DC bias rails, operating symmetrically across both polarities. Use Value: 14.5 V clamping voltage ensures safe margin below 15 V rail tolerance limits while supporting fast <1 ns response to sub-microsecond transients. |
Use Scenario: Secondary-side transient suppression on 12 V or 19 V DC outputs of wall adapters and USB-C PD chargers. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after DC-DC converter output filter to absorb residual switching spikes and ESD events. Use Value: RoHS-compliant and halogen-free (HE3 variant) meets global regulatory requirements for end-user power accessories without compromising surge rating. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V) and VC (14.5 V), but lower PPPM (400 W); SMA package (larger footprint, higher RθJA). | Limited to lower-energy transients; less suitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select when board space allows larger SMA and surge requirements are ≤400 W. |
| 1.5KE10CA | Higher PPPM (1500 W), axial-leaded DO-201 package; slower thermal response and incompatible with SMT assembly. | Requires through-hole mounting and manual assembly; not viable for high-volume automated production. | Choose only for legacy through-hole designs where 1500 W rating justifies rework and layout change. |
Compared with SMAJ10CA and 1.5KE10CA, the P6SMB10CAHE3/52 delivers optimal balance of 600 W surge capability, AEC-Q101 qualification, and SMB footprint - enabling automotive-grade protection in modern SMT-based systems without layout or process compromise.

FAQ
What does the "CA" suffix indicate in P6SMB10CAHE3/52?
The "CA" suffix denotes a bidirectional configuration: the P6SMB10CAHE3/52 provides symmetrical clamping in both polarities, making it suitable for AC-coupled lines or floating nodes where polarity cannot be assumed. Unlike unidirectional variants (e.g., P6SMB10A), it has no cathode band marking and conducts identically in either direction above its breakdown threshold.
Is P6SMB10CAHE3/52 compatible with lead-free reflow soldering?
Yes, the P6SMB10CAHE3/52 meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, and its matte tin-plated leads comply with J-STD-002 and JESD 22-B102. No pre-baking is required, supporting standard Pb-free reflow profiles used in high-volume SMT assembly.
How does the clamping voltage of P6SMB10CAHE3/52 compare to its standoff voltage?
The P6SMB10CAHE3/52 has a 10 V standoff voltage (VWM) and a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current. This 4.5 V differential ensures adequate margin for downstream 12–15 V logic or analog circuits while limiting transient overshoot - a key design parameter for protecting ICs with absolute maximum ratings near 16 V.
What is the significance of the "HE3" suffix in P6SMB10CAHE3/52?
The "HE3" suffix indicates that the P6SMB10CAHE3/52 is RoHS-compliant and AEC-Q101 qualified - validated for automotive applications including temperature cycling, highly accelerated life testing (HALT), and ESD robustness. This distinguishes it from commercial-grade E3 or M3 variants and confirms suitability for under-hood and body-control module use.
Can P6SMB10CAHE3/52 be used in place of a unidirectional TVS like P6SMB10A?
No - the P6SMB10CAHE3/52 is bidirectional and lacks polarity marking, whereas P6SMB10A is unidirectional with a cathode band. Substituting them requires verifying circuit topology: P6SMB10CAHE3/52 works on AC or floating lines; P6SMB10A is mandatory for DC-biased lines where reverse conduction must be blocked. Their electrical specs differ slightly (e.g., ID limit), so direct replacement is not recommended without schematic review.
