Product details
Overview
P6SMB110CAHE3_B/H 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 (10/1000 μs waveform), used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in industrial and automotive electronics.
For engineers reviewing the P6SMB110CAHE3_B/H datasheet, P6SMB110CAHE3_B/H pinout, P6SMB110CAHE3_B/H application, or P6SMB110CAHE3_B/H equivalent, this AEC-Q101 qualified TVS offers verified bidirectional clamping, low incremental surge resistance, and MSL Level 1 moisture sensitivity - critical for high-reliability board-level ESD and surge protection design.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical breakdown (VBR min/max = 105–116 V), clamping (VC = 152 V), and leakage (ID ≤ 1.0 μA at VWM) characteristics in either direction. Its glass-passivated junction ensures stable avalanche performance under repetitive 10/1000 μs transients at 0.01% duty cycle.
Thermal design is constrained by RθJA = 100 °C/W and TJ(max) = +150 °C, requiring PCB copper pad area per Vishay's recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) layout for rated IPPM. The device meets JESD201 Class 2 whisker resistance and is RoHS-compliant with matte tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 110 V - maximum continuous reverse voltage before clamping initiates; defines operating margin below breakdown |
| VBR (Breakdown) | 105–116 V at IT = 1.0 mA - guaranteed avalanche onset range; ensures predictable turn-on during overvoltage events |
| VC (Clamping) | 152 V at IPPM = 3.9 A - peak voltage seen by protected circuit during 10/1000 μs transient; limits stress on downstream components |
| PPPM | 600 W - peak transient energy absorption capability with standard 10/1000 μs waveform; enables robust surge immunity |
| ID (Leakage) | ≤1.0 μA at VWM - ultra-low reverse leakage preserves signal integrity and minimizes standby power loss |
| TJ(max) | +150 °C - maximum junction temperature rating; supports operation in under-hood automotive and industrial environments |
| Package | SMB (DO-214AA) - standardized surface-mount outline with 2.20 mm height and 3.94 mm length; compatible with automated pick-and-place |
Pinout & Package
SMB (DO-214AA) package: surface-mount, bidirectional device with no polarity marking; symmetrical two-terminal construction where both terminals serve as interchangeable anode/cathode depending on transient polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Interchangeable terminal; conducts avalanche current in either direction during overvoltage event |
| Terminal 2 | Anode/Cathode (bidirectional) | Interchangeable terminal; completes symmetrical clamping path with Terminal 1 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance per JESD47 |
| 600 W peak pulse power | Withstands IEC 61000-4-5 Level 4 (4 kV) surge waveforms when properly mounted on 5.0 mm × 5.0 mm copper pads |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without preconditioning; eliminates moisture-related popcorning risk |
| Glass-passivated junction | Ensures stable VBR and low leakage over lifetime; prevents parameter drift under thermal and humidity stress |
| Low clamping ratio (VC/VBR ≈ 1.45) | Minimizes overvoltage overshoot during fast transients; improves protection margin for 100 V-rated components |
Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Protecting 12 V/24 V power rails in body control modules from load dump and inductive kickback. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across supply rail to shunt transient energy to ground. Use Value: Clamps to 152 V during 10/1000 μs surges, preventing damage to MCU, CAN transceivers, and power switches downstream. |
Use Scenario: Safeguarding analog output lines of pressure/temperature sensors in factory automation systems. IC Role / Device Role / Timing Role: Low-capacitance TVS connected between signal line and ground to suppress ESD and cable discharge events. Use Value: Sub-1 μA leakage at 110 V standoff preserves sensor accuracy; 152 V clamping protects 12-bit ADC front-ends. |
| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Inputs |
|
Use Scenario: Shielding Ethernet PHY interfaces and PoE injectors from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary-level TVS on RJ45 port side, coordinated with secondary GDT or polymer-based protection. Use Value: 600 W rating handles IEC 61000-4-5 combination wave (10/700 μs) up to 2 kV; bidirectional symmetry avoids polarity concerns. |
Use Scenario: Guarding microcontroller GPIOs and gate drivers in washing machine motor control boards against brush-commutator noise. IC Role / Device Role / Timing Role: Localized TVS at motor driver input pins to clamp fast-rising commutation spikes (<100 ns). Use Value: 3.9 A IPPM and 152 V VC limit spike amplitude below MOSFET VDS(max); glass passivation ensures long-term stability. |
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 (110 V), VC = 177 V at 3.5 A; lower PPPM (600 W same), but higher clamping voltage (+25 V vs. P6SMB110CAHE3_B/H) | Less effective clamping margin for 100 V-rated components; requires tighter layout due to higher VC | Select when legacy SMBJ footprint compatibility is required and higher VC is acceptable |
| 1.5KE110CA | Through-hole DO-201 package; same VWM/VC specs but larger footprint, higher RθJA (75 °C/W), and no AEC-Q101 qualification | Not suitable for high-density SMT designs or automotive applications requiring qualification evidence | Choose only for prototyping or low-volume through-hole assemblies where reflow compatibility is not needed |
Compared with SMBJ110CA and 1.5KE110CA, P6SMB110CAHE3_B/H delivers superior clamping performance (152 V vs. 177 V), AEC-Q101 qualification for automotive use, and optimized SMB footprint for automated manufacturing - making it the preferred choice for production-grade SMT surge protection.

FAQ
What does the "CA" suffix indicate in P6SMB110CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration: P6SMB110CAHE3_B/H provides symmetrical clamping in both polarities, with identical VBR, VC, and ID characteristics regardless of voltage polarity applied. This eliminates need for polarity-aware placement and simplifies layout for AC-coupled or floating signal lines. Unlike unidirectional variants (e.g., P6SMB110A), the CA version has no cathode band marking.
Is P6SMB110CAHE3_B/H suitable for IEC 61000-4-5 surge testing?
Yes - P6SMB110CAHE3_B/H is rated for 600 W peak pulse power with a 10/1000 μs waveform, which directly supports IEC 61000-4-5 Level 4 (4 kV) testing when mounted per Vishay's recommended 0.2" × 0.2" copper pad layout. Its 152 V clamping voltage ensures protected circuits remain within safe operating limits during standardized surge events.
How does the "HE3_B/H" suffix affect P6SMB110CAHE3_B/H specifications?
The "HE3_B/H" suffix indicates RoHS-compliant construction with AEC-Q101 qualification ("HE3"), automotive revision grade ("B"), and 7" tape-and-reel packaging ("H"). All electrical and thermal specifications match the base P6SMB110CA part; the suffix adds qualification evidence, material compliance, and logistics formatting - no parameter deviation occurs.
What is the maximum allowable PCB trace length for P6SMB110CAHE3_B/H in high-speed transient protection?
Vishay specifies that P6SMB110CAHE3_B/H must be placed within 2 mm of the protected node to minimize inductance-induced voltage overshoot. Longer traces add series inductance that elevates clamped voltage beyond the rated 152 V - especially critical for <100 ns transients. Use direct routing to ground plane with minimum loop area, and avoid vias in the main current path.
Does P6SMB110CAHE3_B/H require derating at elevated ambient temperatures?
Yes - P6SMB110CAHE3_B/H must be derated above TA = 25 °C per Figure 2 in the datasheet: peak pulse power decreases linearly to zero at TJ = +150 °C. At TA = 85 °C, maximum usable IPPM drops to ~2.6 A (vs. 3.9 A at 25 °C). Thermal design must include copper pad area and airflow analysis to maintain junction temperature within limits.
