Product details
Overview
P4SMA100C from Taiwan Semiconductor is a bidirectional surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 100 V working stand-off voltage (VWM), 144 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 400 W peak pulse power rating under 10/1000 μs waveform - deployed in switching mode power supplies and automotive body electronics.
For engineers reviewing the P4SMA100C datasheet, P4SMA100C pinout, P4SMA100C application, or P4SMA100C equivalent, key selection criteria include bidirectional clamping symmetry, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, DO-214AC (SMA) package compatibility, and sub-1 ps response time for fast transient suppression.
Technical Context
The P4SMA100C implements a glass-passivated silicon junction optimized for unidirectional or bidirectional surge suppression without polarity dependence. Its breakdown voltage range (90–110 V at 1 mA test current) ensures stable triggering across temperature, with a ±0.106 %/°C temperature coefficient of VBR and <1 μA reverse leakage at 81 V.
It operates within –55 °C to +150 °C junction temperature range and sustains 40 A non-repetitive forward surge (8.3 ms half-sine), enabling use in high-energy transients while maintaining UL 94V-0 mold compound flammability rating and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 81.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating DC rail margin |
| VBR min/max | 90.0 / 110.0 V @ 1 mA - Tight breakdown window ensures predictable turn-on during surges |
| VC @ IPPM | 144 V @ 2.9 A (10/1000 μs) - Clamping voltage limits downstream IC stress during ESD/EFT events |
| PPPM | 400 W - Peak power handling capability for automotive load-dump and ISO 7637-2 compliant pulses |
| IR @ VWM | <1 μA - Negligible standby power loss and minimal impact on high-impedance sensing circuits |
| Response time | <1.0 ps - Enables suppression of nanosecond-scale transients before sensitive circuitry reacts |
| TJ max | +150 °C - Supports operation in under-hood automotive environments and enclosed power converters |

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 | 600 W PPPM rating, SMB package (larger footprint), 156 V VC @ 3.8 A | Higher power handling but requires PCB layout change; better for sustained surge events | Select when system-level testing shows >400 W surge energy or when thermal derating below 25 °C is critical |
| 1.5SMC100CA | 1500 W PPPM, SMC package (5.3 mm × 4.5 mm), 169 V VC @ 8.9 A | Designed for higher-energy industrial transients; not drop-in due to size and thermal mass | Choose for DIN-rail mounted PLC I/O modules where space allows and ISO 7637-2 Pulse 5a exceeds 100 V |
Compared with SMBJ100CA and 1.5SMC100CA, the P4SMA100C offers optimal balance of compact DO-214AC footprint, 400 W surge capacity, and 144 V clamping for cost-sensitive automotive and industrial control designs where board space and thermal constraints limit larger packages.

FAQ
What does the 'C' suffix indicate in P4SMA100C?
The 'C' suffix in P4SMA100C denotes bidirectional configuration - meaning the device provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., P4SMA100A), the P4SMA100C has no cathode marking and functions identically regardless of voltage polarity applied across its terminals. This makes it ideal for protecting AC-coupled signals or floating power domains where polarity reversal may occur.
Does P4SMA100C meet automotive EMC requirements?
Yes, P4SMA100C meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements for electrical disturbances in road vehicles. Its 400 W peak pulse power rating, 144 V clamping voltage, and sub-1 ps response time enable effective suppression of conducted transients typical in 12 V and 24 V automotive systems. It is commonly used in body control modules, lighting ECUs, and infotainment power inputs where compliance with OEM-level EMC specifications is mandatory.
What is the maximum operating temperature for P4SMA100C?
The P4SMA100C has a maximum junction temperature (TJ MAX) of +150 °C and an operating junction temperature range of –55 °C to +150 °C. This wide thermal range supports deployment in under-hood automotive locations, industrial motor drives, and enclosed LED luminaires. Derating curves in the datasheet confirm usable power dissipation down to 50% at 100 °C ambient, making P4SMA100C suitable for thermally demanding applications without forced cooling.
Can P4SMA100C be used in place of P4SMA100A?
No - P4SMA100C and P4SMA100A are functionally distinct: P4SMA100C is bidirectional, while P4SMA100A is unidirectional with a defined cathode. Substituting one for the other risks incorrect clamping behavior - e.g., using P4SMA100A in a bidirectional signal line may allow damaging reverse conduction. Always verify circuit polarity and transient directionality before selecting between 'C' (bidirectional) and 'A' (unidirectional) variants of the P4SMA100C family.
What packaging and reel quantity is available for P4SMA100C?
P4SMA100C is supplied in DO-214AC (SMA) package format on 7,500-unit tape-and-reel reels, compatible with standard high-speed pick-and-place equipment. The lead finish is matte tin plating, qualified per J-STD-002 for solderability, and the moisture sensitivity level is rated J-STD-020 Level 1 - meaning no dry-pack or baking is required prior to reflow assembly. This simplifies manufacturing logistics for high-volume SMT production lines.
