Product details
Overview
P6SMB100CAHE3_A/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 or power lines. It features a 85.5 V standoff voltage (VWM), 95.0–105 V breakdown voltage (VBR) at 1 mA test current, 137 V maximum clamping voltage at 4.4 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - used to protect automotive sensor interfaces, industrial I/O lines, and telecom line cards.
For engineers reviewing the P6SMB100CAHE3_A/I datasheet, P6SMB100CAHE3_A/I pinout, P6SMB100CAHE3_A/I application, or P6SMB100CAHE3_A/I equivalent, key selection considerations include bidirectional clamping symmetry, AEC-Q101 qualification status, SMB (DO-214AA) package thermal performance, and compliance with IEC 61000-4-2/4-4/4-5 surge immunity requirements.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, delivering identical clamping behavior above ±85.5 V reverse standoff voltage. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at VWM), while the low incremental surge resistance enables effective transient energy diversion without thermal runaway.
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. Its fast response time (<1 ns) and MSL Level 1 moisture sensitivity rating support high-reliability automated SMT assembly in automotive and industrial environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | Same VWM/VBR/VC specs but lower PPPM (400 W); SMA package (DO-214AC), higher RθJA (150 °C/W) | Limited to lower-energy transients; less suitable for automotive load-dump scenarios | Select when cost sensitivity outweighs peak surge margin and board space allows larger footprint |
| SMCJ100CA | Higher PPPM (1500 W); same VWM/VBR/VC; SMC package (DO-214AB), lower RθJA (50 °C/W) | Better thermal performance and surge margin but requires 3× PCB area vs. SMB | Choose for industrial motor drives where sustained surge repetition demands superior heat dissipation |
Compared with SMAJ100CA and SMCJ100CA, P6SMB100CAHE3_A/I delivers optimal balance of automotive qualification, compact SMB footprint, and 600 W surge capability - making it ideal for space-constrained, high-reliability applications where AEC-Q101 compliance and standardized SMT placement are mandatory.

FAQ
What does the "CA" suffix indicate in P6SMB100CAHE3_A/I?
The "CA" suffix denotes a bidirectional configuration - meaning P6SMB100CAHE3_A/I provides symmetrical clamping for both positive and negative transients without polarity dependence. This distinguishes it from unidirectional variants (e.g., P6SMB100A), which require correct anode/cathode orientation. The CA version is essential for protecting AC-coupled or differential signal paths such as CAN, RS-485, or Ethernet interfaces.
Is P6SMB100CAHE3_A/I qualified for automotive use?
Yes, P6SMB100CAHE3_A/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and documentation in Vishay's P6SMB datasheet (Rev. 09-Jan-2024). This qualification covers stress tests including high-temperature operating life, temperature cycling, and ESD - validating its suitability for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is critical.
What is the maximum clamping voltage of P6SMB100CAHE3_A/I and how is it measured?
The maximum clamping voltage (VC) of P6SMB100CAHE3_A/I is 137 V, measured at a peak pulse current (IPPM) of 4.4 A using a standardized 10/1000 μs double-exponential waveform. This value represents the highest voltage that appears across the device during worst-case surge conditions - a key parameter for ensuring downstream ICs remain within their absolute maximum ratings during transient events.
Can P6SMB100CAHE3_A/I replace P6SMB100A in an existing design?
No - P6SMB100CAHE3_A/I is bidirectional while P6SMB100A is unidirectional, so direct substitution requires layout verification. P6SMB100A has polarity marking (cathode band) and conducts only in reverse bias; P6SMB100CAHE3_A/I has no marking and clamps equally in both directions. Swapping without adjusting circuit topology may result in unintended forward conduction or incomplete protection.
What package type does P6SMB100CAHE3_A/I use and what are its mounting requirements?
P6SMB100CAHE3_A/I uses the SMB (DO-214AA) surface-mount package - measuring 4.57 mm × 3.94 mm × 2.20 mm - with matte tin-plated leads. Per Vishay's datasheet, optimal thermal performance requires mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, and it meets J-STD-020 MSL Level 1 for reflow up to 260 °C peak temperature.
