Product details
Overview
P6SMB10CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 41.4 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects signal lines and power rails in sensor interfaces, automotive ECUs, and industrial I/O modules against ESD and inductive switching transients.
For engineers reviewing the P6SMB10CA-E3/5B datasheet, P6SMB10CA-E3/5B pinout, P6SMB10CA-E3/5B application, or P6SMB10CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, 14.5 V VC under 41.4 A surge, RoHS-compliant matte tin terminations, MSL Level 1 rating, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance regardless of transient polarity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<10 μA at VWM), while the low incremental surge resistance enables rapid energy diversion during fast-rising transients (e.g., ISO 7637-2 pulses).
The device is characterized per ANSI/IEEE C62.35, with thermal resistance RθJA = 100 °C/W and RθJL = 20 °C/W. It supports repetitive surges at 0.01% duty cycle and meets JESD201 Class 2 whisker resistance, making it suitable for long-life industrial and automotive-grade deployments where reliability under thermal cycling and mechanical stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1 mA - Confirmed avalanche onset range; ensures predictable turn-on within tight tolerance. |
| VC (Clamping Voltage) | 14.5 V at IPPM = 41.4 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines IC survivability. |
| PPPM (Peak Pulse Power) | 600 W - Sustained transient energy absorption capability without failure under standardized waveform. |
| ID (Reverse Leakage) | ≤10 μA at 10 V - Minimal standby current draw; preserves low-power system integrity. |
| TJ max | 150 °C - Maximum junction temperature; sets thermal derating boundary for high-ambient designs. |

IC Role / Device Role / Timing Role: Low-capacitance (≈200 pF at 0 V) shunt protector placed differential-line-to-ground, preserving signal integrity up to 1 Mbps. Use Value: Maintains communication uptime by clamping common-mode transients to safe levels without distorting edge timing. |
| Consumer Device USB Port | Power Supply Input Stage |
|
Use Scenario: Shielding USB 2.0 D+/D− lines in smart home hubs against contact ESD (±8 kV HBM) and cable discharge events. IC Role / Device Role / Timing Role: Symmetric TVS pair (one per line) referenced to ground, leveraging bidirectional operation to handle both polarity discharges. Use Value: Achieves IEC 61000-4-2 Level 4 compliance without adding series impedance or degrading signal rise/fall times. |
Use Scenario: Secondary-side transient suppression on 12 V DC input rails of embedded power supplies feeding FPGA or microcontroller subsystems. IC Role / Device Role / Timing Role: Parallel-connected clamp across input capacitor, diverting surge energy away from regulator ICs and bulk capacitance. Use Value: Extends supply lifetime by preventing repeated overvoltage stress on LDOs and DC-DC converters during hot-plug or lightning-induced surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10CA | Same VWM (10 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 150 °C/W). | Limited to lower-energy transients; less suitable for automotive load-dump scenarios requiring 600 W. | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin with smaller pad layout. |
| 1.5KE10CA | Higher PPPM (1500 W), axial-leaded DO-201 package; larger size, through-hole mounting only. | Not SMT-compatible; requires PCB redesign and manual assembly; better for prototyping or legacy systems. | Choose only if 600 W is insufficient and board allows axial components; not drop-in for P6SMB10CA-E3/5B footprint. |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CA-E3/5B delivers optimal balance of 600 W surge handling, SMB SMT compatibility, and automotive-grade qualification readiness-making it preferred for volume production of compact, high-reliability electronics where automated assembly and thermal performance are prioritized.

FAQ
What does the "CA" suffix indicate in P6SMB10CA-E3/5B?
The "CA" suffix denotes a bidirectional configuration: P6SMB10CA-E3/5B provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB10A), it has no cathode marking and delivers identical VBR, VC, and IPPM in either polarity-ideal for AC-coupled or floating signal paths where polarity is undefined or alternating.
What is the maximum clamping voltage of P6SMB10CA-E3/5B under surge conditions?
The maximum clamping voltage (VC) of P6SMB10CA-E3/5B is 14.5 V, measured at its rated peak pulse current (IPPM) of 41.4 A using a 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during worst-case transient events and is confirmed per ANSI/IEEE C62.35 test standards in the official Vishay datasheet (Document Number: 88370).
Is P6SMB10CA-E3/5B suitable for automotive applications?
P6SMB10CA-E3/5B itself is RoHS-compliant commercial-grade; however, the P6SMB10CA-HE3_B variant (same electrical specs, AEC-Q101 qualified) is certified for automotive use. Engineers designing for automotive ECUs or ADAS sensors should specify the HE3_B suffix to ensure qualification to AEC-Q101 stress tests-including temperature cycling, humidity bias, and accelerated life testing-while maintaining identical clamping performance as P6SMB10CA-E3/5B.
How does the SMB package of P6SMB10CA-E3/5B compare thermally to larger packages?
The SMB (DO-214AA) package of P6SMB10CA-E3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. While larger packages like DO-201 offer lower RθJA (~50 °C/W), the SMB's compact size enables high-density layouts-provided board-level thermal relief (e.g., thermal vias, extended copper pours) is implemented to manage power dissipation during repetitive surges.
What is the reverse leakage current specification for P6SMB10CA-E3/5B at its stand-off voltage?
P6SMB10CA-E3/5B exhibits a maximum reverse leakage current (ID) of 10 μA at its rated stand-off voltage (VWM) of 10 V, measured at TA = 25 °C. This low leakage preserves signal integrity in high-impedance circuits (e.g., sensor bias networks or ADC reference paths) and remains stable across its full operating temperature range (–65 °C to +150 °C), as verified in Vishay's Electrical Characteristics table (Document Number: 88370, page 2).
