Product details
Overview
P6SMB110CA-E3/52 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). It protects signal lines and power rails in sensor interfaces, industrial I/O modules, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P6SMB110CA-E3/52 datasheet, P6SMB110CA-E3/52 pinout, P6SMB110CA-E3/52 application, or P6SMB110CA-E3/52 equivalent, key selection criteria include bidirectional clamping capability, 152 V VC under 3.9 A surge, RoHS-compliant matte tin terminations, MSL Level 1 rating, and compatibility with automated SMT placement on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional CA construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at 94.0 V) across temperature.
The device delivers 600 W peak pulse power handling per 10/1000 μs waveform with <1 ns response time and low incremental surge resistance - critical for limiting transient energy delivered to downstream ICs like RS-485 transceivers or microcontroller GPIOs. Thermal resistance is 100 °C/W junction-to-ambient (RθJA) on recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 94.0 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below system rail. |
| VBR (Breakdown) | 105–116 V at 1.0 mA - Confirmed breakdown threshold range; ensures reliable turn-on during overvoltage events. |
| VC (Clamping) | 152 V at IPPM = 3.9 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines stress on downstream components. |
| PPPM | 600 W - Surge energy absorption capacity using standardized 10/1000 μs waveform; validates robustness against lightning-induced surges. |
| ID (Leakage) | <1.0 μA at 94.0 V - Minimal reverse leakage preserves signal integrity and power efficiency in high-impedance circuits. |
| TJ max. | +150 °C - Maximum junction temperature; supports operation in industrial environments with elevated ambient temperatures. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 0.220" × 0.130" footprint; compatible with JEDEC J-STD-020 MSL Level 1 reflow. |

| Consumer Power Adapter Input | Automotive Body Control Module |
|
Use Scenario: Secondary-side overvoltage suppression on 12 V DC outputs of wall adapters used in smart home hubs and IoT gateways. IC Role / Device Role / Timing Role: Bidirectional shunt protector across VOUT and GND to absorb coupling transients from primary-side switching noise or load dump events. Use Value: Withstands repetitive 600 W pulses at 0.01% duty cycle, extending adapter lifetime in environments with frequent plug/unplug or shared outlet noise. |
Use Scenario: CAN bus line protection in non-safety-critical body control modules where AEC-Q101 qualification is optional but robustness is required. IC Role / Device Role / Timing Role: Low-capacitance TVS on CAN_H/CAN_L lines to suppress ESD (IEC 61000-4-2 ±15 kV contact) and load dump spikes without distorting 1 Mbps signaling. Use Value: Delivers <1 ns response and 152 V clamping - within ISO 16750-2 load dump Category III limits - while adding <0.5 pF parasitic capacitance per line. |
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-T | Same VWM (94 V), VC (152 V), and PPPM (600 W); identical SMB package; slightly higher ID (5 μA vs. 1 μA). | Designed for broader industrial use; lacks Vishay's AEC-Q101-qualified variant roadmap. | Select when sourcing flexibility across multiple authorized distributors is prioritized over automotive qualification path. |
| 1.5SMC110CA | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W); same electrical specs; larger SMC (DO-214AB) footprint. | Requires PCB layout change; better suited for higher average power dissipation scenarios (>5 W continuous). | Choose only if board space allows SMC and thermal derating margins require lower RθJA than SMB permits. |
Compared with SMBJ110CA-T and 1.5SMC110CA, P6SMB110CA-E3/52 offers tighter leakage control, optimized SMT manufacturability with MSL Level 1, and direct qualification path to AEC-Q101 via HE3 suffix - making it preferred for high-volume industrial and emerging automotive accessory designs.

FAQ
What is the maximum clamping voltage of P6SMB110CA-E3/52 under surge conditions?
The P6SMB110CA-E3/52 has a maximum clamping voltage (VC) of 152 V when subjected to its rated peak pulse current of 3.9 A using the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping occurs rapidly (<1 ns), limiting energy transfer to downstream components such as RS-485 transceivers or microcontroller I/O pins.
Is P6SMB110CA-E3/52 suitable for automotive applications?
P6SMB110CA-E3/52 is RoHS-compliant commercial-grade and not AEC-Q101 qualified; however, Vishay offers the functionally identical P6SMB110CAHE3_B variant (with HE3 suffix) that meets AEC-Q101 requirements. Engineers designing for automotive body electronics may use P6SMB110CA-E3/52 in non-safety-critical modules where qualification is not mandated, but must verify system-level compliance independently. The P6SMB110CA-E3/52 shares identical electrical characteristics and SMB packaging with its automotive-grade counterpart.
What is the reverse leakage current specification for P6SMB110CA-E3/52 at rated standoff voltage?
At the maximum standoff voltage (VWM) of 94.0 V and TA = 25 °C, the P6SMB110CA-E3/52 exhibits a maximum reverse leakage current (ID) of 1.0 μA. This low leakage ensures minimal power loss and signal distortion in high-impedance monitoring circuits, such as those found in precision sensor front-ends or battery-powered IoT nodes. Leakage remains below 5 μA up to +85 °C per Vishay's derating curves in document 88370.
Does P6SMB110CA-E3/52 have polarity markings on the package?
No, P6SMB110CA-E3/52 does not feature polarity markings because it is a bidirectional TVS diode - its Anode and Cathode terminals are functionally interchangeable for transient suppression. Unlike unidirectional variants (e.g., P6SMB110A), the CA version lacks a cathode band or other visual indicator. PCB layout must treat both terminals symmetrically, connecting one to the protected line and the other to ground or reference potential without orientation dependency.
What is the thermal resistance junction-to-ambient for P6SMB110CA-E3/52?
The typical thermal resistance junction-to-ambient (RθJA) for P6SMB110CA-E3/52 is 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88370. This value assumes still air convection and defines the temperature rise above ambient per watt of steady-state power dissipation. For pulsed operation (e.g., 600 W surges), transient thermal impedance curves (Figure 5) govern short-duration heating behavior.
