Product details
Overview
P6SMB110C from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a standoff voltage of 89.2 V, breakdown voltage range of 99–121 V at 1 mA, clamping voltage of 158 V at 3.9 A (10/1000 µs), and operates across –55 °C to +150 °C junction temperature.
For engineers reviewing the P6SMB110C datasheet, P6SMB110C pinout, P6SMB110C application, or P6SMB110C equivalent, key selection criteria include unidirectional vs. bidirectional configuration (C suffix = bidirectional), DO-214AA (SMB) package compatibility, ISO 7637-2 pulse immunity, low leakage (<1 µA @ 89.2 V), and thermal resistance (RθJA = 55 °C/W).
Technical Context
The P6SMB110C implements a glass-passivated silicon avalanche junction optimized for fast transient suppression with sub-1 ps response from 0 V to VBR min. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating systems without polarity constraints.
It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements for automotive electronics and supports surge currents up to 3.9 A (10/1000 µs) while maintaining clamping below 158 V - critical for protecting downstream 100 V-rated MOSFETs and controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 89.2 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VBR (min/max) | 99 V / 121 V at 1 mA - ensures reliable avalanche initiation within defined tolerance band |
| VC @ IPPM | 158 V at 3.9 A (10/1000 µs) - peak clamped voltage seen by protected circuit during worst-case surge |
| PPPSM | 600 W - non-repetitive peak pulse power handling capability per standard waveform |
| IR @ VWM | <1 µA - minimal standby power loss and negligible loading on high-impedance nodes |
| TJ max | +150 °C - enables operation in under-hood automotive or enclosed industrial environments |
| RθJA | 55 °C/W - defines thermal rise above ambient under steady-state power dissipation (3 W) |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, bidirectional configuration with cathode band omitted (symmetrical terminals). Matte tin-plated leads, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Transient current entry point in negative polarity events | Connects to line being protected; forms one side of symmetrical clamping path |
| Cathode (K) | Transient current entry point in positive polarity events | Connects to line being protected; forms other side of symmetrical clamping path - no polarity marking required for bidirectional use |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| ISO 7637-2 compliance | Validated immunity to automotive load-dump and inductive-switching transients (Pulse 1/2a/2b/3a/3b) |
| Moisture sensitivity level 1 | Enables standard SMT reflow without baking or special handling per J-STD-020 |
| UL 94V-0 molding compound | Meets flammability safety requirement for end-equipment certifications (e.g., UL/IEC 62368) |
| Fast response time <1 ps | Clamps transients before sensitive ICs experience overstress - critical for USB, CAN, and sensor interfaces |
Applications
| Automotive Infotainment Power Rails | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs of head units and display modules against load dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed upstream of DC-DC converters and LDOs. Use Value: Clamps surges to ≤158 V, preserving integrity of 100 V-rated input capacitors and MOSFETs per ISO 7637-2 Pulse 5a. | Use Scenario: Safeguarding 24 V digital input channels in programmable logic controllers exposed to relay coil flyback and ESD. IC Role / Device Role / Timing Role: Line-side transient suppressor between field wiring and optocoupler input stage. Use Value: Limits induced transients to safe levels (<158 V) while adding <1 µA leakage - avoids false triggering of 24 V logic thresholds. |
| AC-DC Adapter Secondary Side | Smart Meter Communication Interfaces |
Use Scenario: Overvoltage protection on secondary-side DC bus of offline SMPS used in consumer adapters. IC Role / Device Role / Timing Role: Parallel-connected TVS across bulk capacitor to absorb transformer leakage spikes and rectifier reverse recovery energy. Use Value: 600 W peak power rating handles repetitive switching surges; DO-214AA footprint fits high-density adapter PCB layouts. | Use Scenario: Protecting RS-485 transceivers and PLC modem lines in utility smart meters subjected to lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional clamp on differential bus lines (A/B) referenced to local ground. Use Value: Symmetrical clamping ensures equal protection for both polarities of common-mode surges; 158 V clamping preserves transceiver common-mode range (±12 V). |
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 (Bourns) | Same DO-214AA package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VBR tolerance (±5% vs ±10% for P6SMB110C) | Preferred where tighter breakdown consistency is required across production lots | Select SMBJ110CA when statistical process control demands tighter VBR distribution |
| 1.5KE110CA (ON Semiconductor) | Through-hole DO-15 package, same electrical specs, higher RθJA (75 °C/W), lower moisture sensitivity (MSL 1 still applies) | Suitable for legacy through-hole designs or prototyping where reflow compatibility is not required | Choose 1.5KE110CA only if board assembly uses wave solder or mixed-technology processes |
Compared with SMBJ110CA and 1.5KE110CA, the P6SMB110C offers optimal balance of SMT manufacturability, thermal performance (RθJA = 55 °C/W), and cost-effectiveness for high-volume automotive and industrial power rail protection - without requiring PCB redesign or derating for thermal limits.

FAQ
What does the 'C' suffix indicate in P6SMB110C?
The 'C' suffix in P6SMB110C denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive- and negative-polarity voltage spikes without polarity dependence. This differs from the unidirectional 'A' variant (e.g., P6SMB110A), which requires correct anode/cathode orientation and only clamps in one direction. The P6SMB110C is ideal for AC-coupled lines or floating grounds where polarity cannot be guaranteed.
Does P6SMB110C meet automotive transient immunity standards?
Yes, P6SMB110C meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for automotive electronic components. Its 600 W peak pulse power rating, 158 V clamping voltage at 3.9 A (10/1000 µs), and stable VBR behavior across –55 °C to +150 °C ensure robust protection against load dump, inductive switching, and battery connection transients - making it suitable for front-end protection in body control modules and infotainment systems.
What is the maximum clamping voltage of P6SMB110C under surge conditions?
The maximum clamping voltage of P6SMB110C is 158 V, measured at a peak pulse current (IPPM) of 3.9 A with a 10/1000 µs waveform. This value represents the highest voltage that will appear across the protected circuit during a standardized surge event - critical for ensuring downstream components (e.g., 100 V-rated MOSFETs or regulators) remain within absolute maximum ratings. The clamping performance is guaranteed across the full operating temperature range.
Can P6SMB110C be used in place of P6SMB110A?
No - P6SMB110C and P6SMB110A are not interchangeable without circuit review. P6SMB110C is bidirectional and has no polarity marking, while P6SMB110A is unidirectional with a cathode band and only clamps in the reverse direction. Substituting P6SMB110C for P6SMB110A may cause unintended conduction in forward bias or fail to protect correctly in DC-biased applications. Always verify polarity requirements and clamping symmetry before replacement.
What is the thermal resistance of P6SMB110C, and how does it affect layout design?
P6SMB110C has a junction-to-ambient thermal resistance (RθJA) of 55 °C/W and junction-to-case (RθJC) of 10 °C/W. These values mean that under 3 W steady-state dissipation, the junction temperature rises ~165 °C above ambient - exceeding its 150 °C limit. Therefore, P6SMB110C must be used in transient-only mode (not continuous power), and PCB copper area should maximize heat spreading to keep peak junction temperature within spec during surge events. No heatsink is required for pulsed operation.
