Product details
Overview
P6SMB10CAHE3_B/I 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 automotive sensor interfaces, industrial I/O modules, and telecom front-end circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB10CAHE3_B/I datasheet, P6SMB10CAHE3_B/I pinout, P6SMB10CAHE3_B/I application, or P6SMB10CAHE3_B/I equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 100 °C/W junction-to-ambient thermal resistance, and compatibility with automated SMT assembly on standard PCB pad layouts per JEDEC DO-214AA footprint.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical breakdown in both polarities due to its bidirectional construction. It exhibits 6.8 V minimum and 10.5 V maximum breakdown voltage (VBR) at 1 mA test current, and maintains ≤1 μA reverse leakage at 8.55 V standoff voltage (VWM).
Thermally, it supports operation from –65 °C to +150 °C junction temperature, with derating above 25 °C ambient per Fig. 2 of the datasheet. Its glass-passivated junction ensures stable surge performance, and MSL Level 1 rating confirms suitability for lead-free reflow up to 260 °C peak.

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 (8.55 V) and VC (14.5 V), but lower PPPM (400 W); SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; less suitable for automotive load-dump scenarios requiring 600 W margin. | Select when board space is constrained and surge requirements are ≤400 W (e.g., consumer USB ports). |
| 1.5KE10CA | Higher PPPM (1500 W), through-hole DO-201 package; larger size, manual or wave-solder only. | Not SMT-compatible; requires PCB real estate and assembly process change; better for high-reliability industrial power supplies. | Choose for legacy designs or where mechanical robustness outweighs automation needs and board area is available. |
Compared with SMAJ10CA and 1.5KE10CA, P6SMB10CAHE3_B/I delivers optimal balance of 600 W surge capacity, AEC-Q101 qualification, and SMB SMT compatibility-making it preferred for new automotive and industrial designs requiring automated manufacturing and validated automotive reliability.

FAQ
What does the "CA" suffix indicate in P6SMB10CAHE3_B/I?
The "CA" suffix denotes a bidirectional configuration: P6SMB10CAHE3_B/I provides symmetrical clamping in both polarities, making it suitable for AC signal lines, differential buses, or floating nodes where polarity cannot be guaranteed. Unlike unidirectional variants (e.g., P6SMB10A), it has no cathode marking and identical electrical behavior regardless of terminal orientation. This is confirmed in the Vishay P6SMB datasheet section "DEVICES FOR BIDIRECTION APPLICATIONS".
Is P6SMB10CAHE3_B/I qualified for automotive applications?
Yes, P6SMB10CAHE3_B/I is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in the ordering code. The "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction, while "_B" specifies AEC-Q101 qualification for the 6.8 V to 220 V voltage range. This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating its use in automotive powertrain, chassis, and body electronics.
What is the clamping voltage of P6SMB10CAHE3_B/I under surge conditions?
P6SMB10CAHE3_B/I has a maximum clamping voltage (VC) of 14.5 V at 41.4 A peak pulse current (IPPM), measured with a 10/1000 μs waveform. This value is specified in the Electrical Characteristics table of the Vishay datasheet (Document Number: 88370, page 2) and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events-critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB package of P6SMB10CAHE3_B/I compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB10CAHE3_B/I measures 4.06 mm × 5.59 mm with 2.20 mm height, offering higher power handling than SMA (DO-214AC) and smaller footprint than SMC (DO-214AB). Its 100 °C/W RθJA is optimized for 0.2" × 0.2" copper pads, striking a balance between thermal performance and board area-unlike SMA's 140 °C/W (less efficient cooling) or SMC's 60 °C/W (larger layout impact). This makes P6SMB10CAHE3_B/I ideal for space-constrained yet thermally demanding applications.
Can P6SMB10CAHE3_B/I be used in place of P6SMB10A in a design?
No-P6SMB10CAHE3_B/I is bidirectional while P6SMB10A is unidirectional, meaning they differ fundamentally in polarity behavior and circuit integration. Substituting them without layout review risks improper clamping during negative transients or forward conduction in DC-biased paths. The datasheet explicitly separates CA (bidirectional) and A (unidirectional) variants in tables and application notes, confirming non-interchangeability without redesign.
