Product details
Overview
P6SMB110CH from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a nominal breakdown voltage of 110 V, clamping voltage of 158 V at 3.9 A peak pulse current, and DO-214AA (SMB) package. It provides robust ESD and electrical fast transient protection for automotive power line interfaces and industrial control I/O circuits.
For engineers reviewing the P6SMB110CH datasheet, P6SMB110CH pinout, P6SMB110CH application, or P6SMB110CH equivalent, this device is selected for high-energy surge immunity in 12 V/24 V automotive subsystems, CAN bus front-end protection, and DC power rail stabilization where bidirectional clamping and AEC-Q101 qualification are required.
Technical Context
The P6SMB110CH is a unidirectional/bidirectional TVS diode configured as a single die in a glass-passivated junction structure. Its 150 °C maximum junction temperature and 10 °C/W junction-to-case thermal resistance support sustained operation under repetitive surge conditions in enclosed automotive modules.
It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b waveforms and delivers sub-1 ps response time from 0 V to VBR(min). The device exhibits <1 µA reverse leakage at 89.2 V standoff voltage and a 0.107 %/°C temperature coefficient of breakdown voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 99 V / 121 V - Ensures reliable conduction onset across temperature and production lot variation |
| VWM | 89.2 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 158 V at 3.9 A - Clamped voltage during 10/1000 µs surge limits downstream IC stress |
| PPPSM | 600 W - Peak pulse power handling capability per single 10/1000 µs transient |
| Junction Temp (TJ) | -55 °C to +150 °C - Enables deployment in under-hood automotive environments |
| Package | DO-214AA (SMB) - Surface-mount footprint compatible with automated assembly and IPC-7351B land patterns |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling and HTRB |
Pinout & Package
DO-214AA (SMB) package: molded plastic case with matte tin-plated leads, polarity indicated by cathode band; weight ≈ 0.090 g; UL 94V-0 rated compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Cathode Band Side) | Reverse-biased terminal for bidirectional clamping | Terminal marked with cathode band serves as reference node for both polarities in CH configuration |
| Cathode (Opposite Band) | Reverse-biased terminal for bidirectional clamping | Paired with anode to form symmetrical clamping path; no intrinsic polarity distinction in CH devices |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR, VC, and IPPM performance in both directions - eliminates polarity-dependent layout constraints |
| AEC-Q101 qualification | Validated for automotive applications including temperature cycling, HTRB, and mechanical shock - supports ASIL-B system integration |
| Low leakage at VWM | <1 µA at 89.2 V - minimizes standby power loss in always-on vehicle networks |
| Fast response time | <1.0 ps rise to VBR(min) - intercepts ESD and EFT transients before sensitive logic thresholds are violated |
| ISO 7637-2 compliance | Passes Pulse 1 (inductive load dump), Pulse 2a/2b (supply disconnection), and Pulse 3a/3b (switching noise) - certified for 12 V/24 V power line protection |
Applications
| Automotive Power Line Protection | CAN Bus Transceiver Front-End |
|---|---|
Use Scenario: 12 V battery line in engine control units exposed to load dump and jump-start surges. IC Role / Device Role: Primary overvoltage clamp upstream of DC-DC converters and microcontroller power supplies. Use Value: Limits transient voltage to ≤158 V during 600 W pulses, preventing latch-up or permanent damage to 3.3 V/5 V logic rails. |
Use Scenario: Signal lines of high-speed CAN FD transceivers in body control modules. IC Role / Device Role: Bidirectional ESD and EFT suppressor placed directly at connector interface. Use Value: Clamps ±15 kV contact ESD per IEC 61000-4-2 without signal distortion due to low capacitance (<100 pF at 0 V). |
| Industrial PLC Digital I/O Protection | DC Power Rail Stabilization |
Use Scenario: 24 V digital input channels subject to inductive switching transients from solenoid drivers. IC Role / Device Role: Input-side TVS on optocoupler or Schmitt trigger inputs. Use Value: Absorbs 10/1000 µs surges up to 3.9 A while maintaining <1 µA leakage at 24 V nominal operation. |
Use Scenario: Secondary-side 48 V DC distribution rail in telecom power systems. IC Role / Device Role: Secondary clamping device parallel to bulk capacitor to suppress overshoot during hot-swap events. Use Value: Activates at 99–121 V breakdown to prevent overvoltage trip of downstream POL converters rated for 54 V max. |
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 DO-214AA package, identical 110 V VBR range and 600 W rating; slightly higher VC (162 V vs. 158 V) | Approved for industrial but not AEC-Q101 qualified - unsuitable for automotive under-hood use | Select when AEC-Q101 is not required and minor clamping voltage increase is acceptable |
| 1.5KE110CA | Through-hole DO-201 package; same 110 V VBR and 600 W rating; higher VC (175 V) and slower response (>1 ns) | Larger footprint and incompatible with SMT-only PCBs; lacks ISO 7637-2 certification | Choose only for legacy through-hole designs where rework to SMB is impractical |
Compared with SMBJ110CA and 1.5KE110CA, the P6SMB110CH offers AEC-Q101 qualification, lower clamping voltage, and ISO 7637-2 compliance - making it the sole option for new automotive power line designs requiring validated reliability and precise transient suppression.

FAQ
What does the 'CH' suffix indicate in P6SMB110CH?
The 'CH' suffix denotes a bidirectional configuration with symmetrical clamping characteristics in both polarities. Unlike unidirectional 'H' variants, the P6SMB110CH has identical breakdown and clamping behavior regardless of voltage polarity - essential for protecting AC-coupled or differential signal lines such as CAN or LIN buses.
Is P6SMB110CH suitable for 24 V automotive systems?
Yes, the P6SMB110CH is specifically designed for 24 V nominal systems: its 89.2 V standoff voltage (VWM) exceeds typical 24 V rail transients, while its 99–121 V breakdown range ensures activation only during fault conditions. It is AEC-Q101 qualified and tested per ISO 7637-2 Pulse 1 and 2a, confirming suitability for commercial and light-duty vehicle applications.
How does P6SMB110CH compare to P6SMB110AH?
The P6SMB110AH is a unidirectional variant with anode-cathode asymmetry and a cathode band marking; the P6SMB110CH is bidirectional with no functional polarity. Their electrical specs differ: P6SMB110AH has VBR = 105–116 V and VC = 152 V, whereas P6SMB110CH has VBR = 99–121 V and VC = 158 V. Use P6SMB110CH when polarity-agnostic protection is needed.
What is the maximum peak pulse current rating for P6SMB110CH?
The P6SMB110CH has a maximum peak pulse current (IPPM) of 3.9 A under the standard 10/1000 µs waveform. This value is derived from its 600 W peak pulse power rating and 158 V clamping voltage (IPPM = PPPSM/VC). Derating applies above 25 °C ambient per the published pulse derating curve.
Does P6SMB110CH meet RoHS and halogen-free requirements?
Yes, the P6SMB110CH is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, terminals are matte tin-plated, and the device meets J-STD-020 moisture sensitivity level 1 - enabling lead-free reflow processing without preconditioning.
