Product details
Overview
P6SMB110CAHE3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 110 V standoff voltage (VWM), 152 V clamping voltage (VC) at 3.9 A peak pulse current (IPPM), and 600 W peak pulse power (PPPM) with 10/1000 μs waveform. It protects sensitive signal lines and power rails in automotive, industrial, and telecom systems against ESD, lightning surges, and inductive switching transients.
For engineers reviewing the P6SMB110CAHE3/5B datasheet, P6SMB110CAHE3/5B pinout, P6SMB110CAHE3/5B application, or P6SMB110CAHE3/5B equivalent, key selection criteria include bidirectional clamping behavior, AEC-Q101 qualification, 150 °C max junction temperature, low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
The P6SMB110CAHE3/5B operates as a voltage-clamped surge protection device with symmetrical reverse/forward breakdown characteristics due to its bidirectional construction. It exhibits a 105–116 V breakdown voltage (VBR) at 1 mA test current and maintains stable clamping up to 152 V under 3.9 A transient current.
Its glass-passivated junction ensures fast response time (<1 ns), low incremental surge resistance, and robust reliability under repetitive 0.01% duty cycle pulses. The device meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 94.0 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown) | 105–116 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping) | 152 V at IPPM = 3.9 A - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; limits stress on downstream ICs |
| PPPM | 600 W - Surge energy handling capacity with standardized 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 3/4 transients |
| RθJL | 20 °C/W - Junction-to-lead thermal resistance; supports reliable power dissipation without external heatsinking on standard 5.0 mm × 5.0 mm copper pads |
| TJ max | +150 °C - Maximum junction temperature rating; allows operation in under-hood automotive and high-ambient industrial environments |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Bidirectional construction means no polarity marking; both terminals are electrically symmetric.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient current path | Either terminal conducts during positive or negative voltage excursions beyond VBR; no cathode band marking required |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ110CA | Same VWM (94 V), VC (152 V), and PPPM (600 W); SMA package (DO-214AC), higher RθJA (140 °C/W) vs. SMB's 100 °C/W | Larger footprint; less suitable for dense automotive PCBs where SMB's smaller size saves board area | Select P6SMB110CAHE3/5B when space-constrained layout or lower thermal resistance is required |
| 1.5KE110CA | Through-hole TO-204AE (DO-201AE); same electrical specs but 1.5 kW PPPM rating and higher VC (170 V) | Not SMT-compatible; requires wave soldering and larger keep-out; unsuitable for automated high-volume production | Choose P6SMB110CAHE3/5B for surface-mount manufacturing, AEC-Q101 compliance, and compact design |
Compared with SMAJ110CA and 1.5KE110CA, the P6SMB110CAHE3/5B offers superior thermal performance in a smaller footprint and is the only one qualified to AEC-Q101-making it the preferred choice for automotive and space-sensitive industrial designs requiring zero rework risk and full traceability.

FAQ
What does the "CA" suffix mean in P6SMB110CAHE3/5B?
The "CA" suffix denotes a bidirectional configuration: the P6SMB110CAHE3/5B provides symmetrical clamping for both positive and negative voltage transients, making it ideal for protecting AC-coupled signals, differential buses like CAN or RS-485, and ungrounded power rails without polarity concerns.
Is P6SMB110CAHE3/5B suitable for automotive applications?
Yes-the P6SMB110CAHE3/5B carries AEC-Q101 qualification (indicated by the "HE3" suffix and "_B" revision code), confirming compliance with automotive reliability tests including temperature cycling, high-temperature reverse bias, and ESD. It is approved for under-hood and chassis-mounted modules.
What is the clamping voltage of P6SMB110CAHE3/5B under surge conditions?
The P6SMB110CAHE3/5B clamps to a maximum of 152 V when subjected to its rated peak pulse current of 3.9 A (10/1000 μs waveform). This value is guaranteed across temperature and lifetime, ensuring consistent protection margin for 100 V-rated downstream components.
How does the SMB package of P6SMB110CAHE3/5B compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB110CAHE3/5B offers a 30% smaller footprint than SMA (DO-214AC) and 50% smaller than SMC (DO-214AB), while maintaining 600 W PPPM and lower thermal resistance (RθJL = 20 °C/W). Its MSL Level 1 rating also eliminates bake requirements pre-reflow.
Does P6SMB110CAHE3/5B require a heatsink for 600 W surge handling?
No-P6SMB110CAHE3/5B is rated for 600 W peak pulse power with no heatsink when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. Its RθJL of 20 °C/W enables sufficient heat transfer to PCB copper, eliminating need for additional thermal management.
