Product details
Overview
P4SMA10C from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails. It features a 10V working stand-off voltage (VWM), 15.0V maximum clamping voltage (VC) at 28A peak pulse current, and sub-1ps response time-ideal for safeguarding sensitive inputs in switching mode power supplies and on-board DC/DC converters.
For engineers reviewing the P4SMA10C datasheet, P4SMA10C pinout, P4SMA10C application, or P4SMA10C equivalent, key selection criteria include its DO-214AC (SMA) package compatibility, bidirectional capability (C suffix), low leakage (<10µA at 8.1V), and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance for automotive-grade surge immunity.
Technical Context
The P4SMA10C is a unidirectional TVS diode with glass-passivated junction and single-die construction in DO-214AC (SMA) package. Its breakdown voltage (VBR) is specified at 9.0–11.0V @ 1.0mA test current, and it delivers 400W peak pulse power under 10/1000μs waveform per IEC 61000-4-5.
It operates across -55°C to +150°C junction temperature range, supports 40A non-repetitive forward surge current (IFSM), and exhibits <1μA reverse leakage above 10V-enabling reliable protection in high-reliability industrial and automotive power interfaces without compromising standby efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 8.1 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 9.0 / 11.0 V @ 1.0 mA - Ensures predictable turn-on threshold across process variation |

| PPPM | 400 W (10/1000 μs) - Withstands automotive load dump and inductive switching surges |
| IR @ VWM | <10 µA - Minimizes quiescent power loss in battery-backed or low-power systems |
| TJ max | +150 °C - Supports operation in enclosed, thermally constrained environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A (Bourns) | Higher VWM (8.55V), lower VC (17.0V @ 23.3A), SMB package (larger footprint) | Preferred where higher surge margin is needed but board space allows larger package | Select SMBJ10A if layout permits SMB footprint and system requires tighter VBR tolerance (±5%) |
| 1.5SMC10A (ON Semiconductor) | Same VWM (8.55V), same VC (17.0V), but SMC package (5.3mm × 5.3mm vs SMA 4.5mm × 2.7mm) | Better thermal mass for repetitive surge duty; not suitable for ultra-dense layouts | Choose 1.5SMC10A when thermal cycling endurance under frequent transients is critical |
Compared with P4SMA10C, SMBJ10A offers tighter VBR tolerance but requires more PCB area, while 1.5SMC10A provides superior thermal handling at the cost of footprint size-making P4SMA10C optimal for space-constrained, high-volume automotive and industrial modules requiring DO-214AC compatibility.

Manufacturer
Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, specializing in TVS diodes, rectifiers, and power devices since 1979.

FAQ
What is the clamping voltage of P4SMA10C under a 10/1000μs surge?
The P4SMA10C has a maximum clamping voltage (VC) of 15.0 V when subjected to a 10/1000μs waveform at its rated peak pulse current of 28.0 A. This value is measured per IEC 61000-4-5 and ensures downstream components see no more than 15.0 V during standardized surge events. The P4SMA10C maintains this clamping performance across its full operating temperature range of -55°C to +150°C.
Is P4SMA10C unidirectional or bidirectional?
P4SMA10C is a unidirectional TVS diode, indicated by the "C" suffix per Taiwan Semiconductor's naming convention (where "CA" denotes bidirectional). It functions as a reverse-biased Zener clamp with cathode band marking and is intended for DC rail protection where polarity is fixed. For bidirectional AC or floating signal line protection, P4SMA10CA would be the appropriate variant.
What does the "C" suffix mean in P4SMA10C?
In Taiwan Semiconductor's P4SMA family, the "C" suffix identifies the unidirectional version with standard cathode-band polarity marking. It distinguishes P4SMA10C from the bidirectional P4SMA10CA and the tighter-tolerance "A" grade (e.g., P4SMA10A). The "C" variant meets all base electrical specs-including 9.0–11.0V VBR, 8.1V VWM, and 15.0V VC-but is not rated for symmetrical bipolar clamping.
Can P4SMA10C replace P4SMA10A in a design?
P4SMA10C and P4SMA10A share identical VWM (8.1V) and VC (15.0V), but differ in VBR tolerance: P4SMA10C specifies 9.0–11.0V (±10%), while P4SMA10A tightens this to 9.5–10.5V (±5%). If your design relies on precise clamping onset-for example, to avoid false triggering near nominal rail voltage-P4SMA10A is preferred. Otherwise, P4SMA10C remains functionally interchangeable with verified margin.
Does P4SMA10C comply with automotive surge standards?
Yes, P4SMA10C meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling), as confirmed in Taiwan Semiconductor's official documentation. Its 400W peak pulse rating, sub-1ps response, and 150°C TJ max make it suitable for engine control units, body control modules, and other automotive ECUs requiring validated transient immunity.
