Product details
Overview
P6SMB110CAHE3/52 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 waveform). It protects signal lines and power rails in automotive sensor units and industrial control interfaces against ESD and inductive switching transients.
For engineers reviewing the P6SMB110CAHE3/52 datasheet, P6SMB110CAHE3/52 pinout, P6SMB110CAHE3/52 application, or P6SMB110CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 150 °C maximum junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on standard PCB pad layouts.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM = 94.0 V).
The device delivers 600 W peak pulse power handling under standardized 10/1000 μs waveform conditions with 0.01 % duty cycle, and exhibits fast response time (<1.0 ns) and low clamping ratio (VC/VWM ≈ 1.62), critical for safeguarding sensitive MOSFET gates and microcontroller I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before clamping begins; defines operating margin below breakdown. |
| VBR (Breakdown Voltage) | 105–116 V at 1.0 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 152 V at IPPM = 3.9 A - Peak voltage seen by protected circuit during worst-case 600 W transient; limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W (10/1000 μs) - Sustains high-energy surges common in automotive load-dump or industrial relay-switching events. |
| ID (Reverse Leakage) | ≤1.0 μA at VWM - Negligible standby current; avoids signal distortion or battery drain in always-on systems. |
| TJ max. | 150 °C - Enables reliable operation in under-hood automotive environments and enclosed industrial enclosures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case with matte tin-plated leads compliant with J-STD-002 and JESD22-B102 solderability requirements. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (bidirectional) | One terminal of symmetrical PN junction; accepts surge current from either direction during overvoltage events. |
| Cathode | Transient current exit (bidirectional) | Second terminal of symmetrical PN junction; completes low-impedance path to ground or reference rail during clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), and floating power domains without external polarity management. |
| 600 W peak pulse power | Withstands high-energy transients from inductive loads (e.g., solenoids, motors) in industrial PLC I/O modules without degradation. |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive applications including body electronics, ADAS sensor interfaces, and infotainment power rails. |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles; no moisture sensitivity concerns prior to assembly. |
| Low clamping ratio (VC/VWM = 1.62) | Minimizes voltage overshoot during clamping, reducing risk of latch-up or gate oxide damage in protected ICs. |
Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus nodes and analog sensor outputs (e.g., pressure, temperature) from load-dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed across differential signal pair or supply-to-ground to limit transient voltage excursion.

Use Scenario: Overvoltage protection on twisted-pair DSL lines entering residential gateways, exposed to induced surges from nearby power lines. IC Role / Device Role / Timing Role: Bidirectional TVS installed line-to-line and line-to-ground to clamp mode-specific transients while preserving low-capacitance signal path. Use Value: Limits junction capacitance to <100 pF (typ.) at 0 V bias, ensuring minimal impact on ADSL/VDSL signal attenuation up to 30 MHz. |
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 = 152 V, but rated for 600 W with tighter VBR tolerance (105–116 V vs. 105–116 V); identical SMB package and AEC-Q101 qualification (HE3 variant available). | No functional difference in clamping performance or footprint; differs only in branding and internal lot traceability. | Select SMBJ110CA if dual-sourcing from multiple authorized distributors is required without design change. |
| 1.5KE110CA | Higher package thermal resistance (RθJA ≈ 150 °C/W vs. 100 °C/W), through-hole DO-201AD package, same VWM/VC ratings but lower mounting density and manual assembly requirement. | Suitable for prototyping or legacy through-hole designs; not compatible with automated SMT lines or space-constrained PCBs. | Choose 1.5KE110CA only for hand-soldered evaluation or where board real estate allows larger footprint and higher thermal budget. |
Compared with SMBJ110CA, P6SMB110CAHE3/52 offers identical electrical performance and AEC-Q101 compliance in the same SMB package, while 1.5KE110CA requires layout redesign and sacrifices SMT scalability-making P6SMB110CAHE3/52 optimal for high-volume automotive and industrial production.

How does the bidirectional configuration of the P6SMB110CAHE3/52 affect its PCB layout?
The P6SMB110CAHE3/52 has no polarity marking and functions identically in both directions, simplifying PCB layout by eliminating orientation constraints. It can be placed across differential lines (e.g., RS-485 A/B), AC-coupled inputs, or floating grounds without concern for anode/cathode alignment-reducing assembly errors and enabling symmetric routing in noise-sensitive analog sections.
What is the maximum operating junction temperature for the P6SMB110CAHE3/52?
The P6SMB110CAHE3/52 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay's thermal characterization in Document 88370. This rating supports operation in under-hood automotive environments and sealed industrial enclosures, provided PCB copper pad area meets the 0.2" × 0.2" (5.0 mm × 5.0 mm) minimum recommendation for thermal dissipation.
Does the P6SMB110CAHE3/52 meet RoHS and halogen-free requirements?
