Product details
Overview
P6SMB100C 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 81.0 V, breakdown voltage range of 90–110 V at 1 mA test current, clamping voltage of 144 V at 4.3 A peak pulse current, and operates across –55°C to +150°C junction temperature. It is used in automotive infotainment power supplies to absorb ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB100C datasheet, P6SMB100C pinout, P6SMB100C application, or P6SMB100C equivalent, key selection criteria include its bidirectional configuration, DO-214AA (SMB) package compatibility with automated placement, sub-1 μA leakage at 81 V, and verified compliance with ISO 7637-2 for automotive surge immunity.
Technical Context
The P6SMB100C employs a glass-passivated silicon junction optimized for fast transient response (<1.0 ps rise time from 0 V to VBR min) and stable clamping under repetitive or single-event surges. Its unidirectional counterpart (P6SMB100) has VF = 5.0 V at 50 A, but P6SMB100C is symmetrical-electrical characteristics apply identically in both directions.
Thermal performance is defined by RθJC = 10°C/W and RθJA = 55°C/W, enabling reliable operation at up to 150°C junction temperature. It meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1, supporting lead-free reflow without preconditioning.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100CA | Same DO-214AA package, identical 100 V nominal breakdown, but rated at 600 W with tighter VBR tolerance (95–105 V) and lower VC (137 V @ 4.4 A) | Preferred where lower clamping voltage is critical for 12 V system margin; not qualified to ISO 7637-2 in manufacturer documentation | Select SMBJ100CA when clamping voltage reduction outweighs automotive standard validation needs |
| 1.5KE100CA | Higher power (1500 W), axial-leaded DO-15 package, VBR = 95–105 V, VC = 150 V @ 10 A, slower response (>1 ns) | Requires through-hole assembly and larger board area; suitable for non-automotive industrial mains input stages | Choose 1.5KE100CA only if higher surge energy absorption is needed and surface-mount constraint is relaxed |

FAQ
What does the 'C' suffix indicate in P6SMB100C?
The 'C' suffix in P6SMB100C designates a bidirectional configuration. Unlike unidirectional variants (e.g., P6SMB100), the P6SMB100C provides symmetrical breakdown and clamping behavior in both forward and reverse directions, with identical VBR, VC, and IPPM specifications regardless of polarity. This eliminates orientation dependency during PCB placement.
Does P6SMB100C meet automotive surge standards?
Yes, P6SMB100C meets ISO 7637-2 requirements for Pulse 1 (inductive load dump), Pulse 2a/2b (supply interruption), and Pulse 3a/3b (capacitive coupling), as explicitly stated in the official Taiwan Semiconductor datasheet. Its 600 W peak pulse power rating and 144 V clamping voltage are validated under these waveforms, making it suitable for automotive ECU and infotainment front-end protection.
What is the maximum clamping voltage for P6SMB100C under surge conditions?
The maximum clamping voltage for P6SMB100C is 144 V, measured at 4.3 A peak pulse current using the standardized 10/1000 µs waveform. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range (–55°C to +150°C).
Is P6SMB100C compatible with lead-free reflow processes?
Yes, P6SMB100C is fully compatible with lead-free reflow soldering. It is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions without baking. The matte tin-plated leads meet J-STD-002 solderability requirements, and the UL 94V-0 molding compound withstands peak reflow temperatures up to 260°C.
How does P6SMB100C differ from P6SMB100A?
P6SMB100A is a unidirectional variant with tighter VBR tolerance (95–105 V vs. 90–110 V for P6SMB100C) and lower clamping voltage (137 V @ 4.5 A). In contrast, P6SMB100C is bidirectional with symmetrical electrical characteristics in both directions and uses a 'C' suffix per datasheet Note 4. They share the same DO-214AA package and thermal ratings but serve distinct circuit roles-P6SMB100C for AC-coupled or polarity-agnostic protection, P6SMB100A for DC rail clamping with defined polarity.
