Product details
Overview
P6SMB110CAHE3_B/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal and power lines. It features a 110 V standoff voltage (VWM), 125 V maximum clamping voltage at 3.9 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform. It is AEC-Q101 qualified and used to protect MOSFETs, ICs, and sensor signal lines in automotive and industrial electronics.
For engineers reviewing the P6SMB110CAHE3_B/I datasheet, P6SMB110CAHE3_B/I pinout, P6SMB110CAHE3_B/I application, or P6SMB110CAHE3_B/I equivalent, key selection considerations include bidirectional transient suppression capability, SMB (DO-214AA) package compatibility, AEC-Q101 qualification status, clamping performance under 10/1000 μs surge, and RoHS-compliant matte tin plating for solderability.
Technical Context
This bidirectional TVS diode operates symmetrically across both polarities, delivering identical clamping behavior in forward and reverse directions. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables effective energy diversion during fast transients.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements, supporting 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 |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 V), VC = 125 V, but rated for 600 W with 8.3 ms half-sine surge (not 10/1000 μs); lower IFSM (100 A vs. 100 A same). | Optimized for longer-duration surges (e.g., AC line faults); less precise for fast ESD/EFT events. | Select SMBJ110CA only if system-level testing confirms 8.3 ms surge dominance and 10/1000 μs immunity is secondary. |
| 1.5SMC110CA | Same VWM/VC specs, but in larger SMC (DO-214AB) package (7.11 mm × 6.22 mm); higher thermal mass but incompatible with SMB footprints. | Used where board space allows larger package and higher sustained power dissipation is needed. | Choose 1.5SMC110CA only when PCB layout permits SMC footprint and thermal design requires RθJA < 100 °C/W. |
Compared with SMBJ110CA and 1.5SMC110CA, P6SMB110CAHE3_B/I offers optimal balance of compact SMB footprint, AEC-Q101 qualification, and precise 10/1000 μs clamping response-making it the preferred choice for space-constrained automotive and industrial PCBs requiring validated automotive reliability.

FAQ
What does the "CA" suffix indicate in P6SMB110CAHE3_B/I?
The "CA" suffix in P6SMB110CAHE3_B/I denotes a bidirectional configuration-meaning the device provides symmetrical transient suppression in both polarities, with identical VWM, VBR, and VC values regardless of voltage polarity. This eliminates the need for polarity-aware placement and simplifies protection of AC-coupled or differential signal paths. The P6SMB110CAHE3_B/I achieves this using a back-to-back diode structure within a single SMB package.
Is P6SMB110CAHE3_B/I suitable for automotive applications?
Yes, P6SMB110CAHE3_B/I is AEC-Q101 qualified, as confirmed by the "HE3_B" suffix and Vishay documentation. It undergoes rigorous stress testing-including temperature cycling, high-temperature reverse bias, and ESD-to ensure reliability in automotive environments such as engine control units, body electronics, and ADAS sensor modules. Its 150 °C TJ max and MSL Level 1 rating further support under-hood and infotainment system deployment.
What is the clamping voltage of P6SMB110CAHE3_B/I under a standard 10/1000 μs surge?
The maximum clamping voltage (VC) of P6SMB110CAHE3_B/I is 125 V when subjected to its rated peak pulse current of 3.9 A with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet (Document Number: 88370) and represents the upper voltage limit imposed on protected circuitry during standardized surge events-critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the SMB (DO-214AA) package of P6SMB110CAHE3_B/I compare to SMC or SMA alternatives?
The SMB (DO-214AA) package of P6SMB110CAHE3_B/I measures 3.94 mm × 2.20 mm-smaller than SMC (DO-214AB) and larger than SMA (DO-214AC). Its 100 °C/W RθJA is optimized for standard 0.2" × 0.2" copper pads, offering better power density than SMA while maintaining compatibility with fine-pitch automated assembly. Unlike SMC, SMB avoids layout redesign when upgrading from SMA-level protection without needing extra board area.
Does P6SMB110CAHE3_B/I require derating at elevated ambient temperatures?
Yes, P6SMB110CAHE3_B/I must be derated above TA = 25 °C per Figure 2 in the Vishay datasheet. Its peak pulse power drops linearly to 50% at 125 °C ambient, and its maximum junction temperature remains capped at 150 °C. Designers must apply the published derating curve when operating in enclosures exceeding 70 °C ambient-especially in automotive junction boxes or industrial drives-to maintain 600 W surge capability and avoid thermal runaway.
