Product details
Overview
P4SMA13C from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with 11.7–14.3V breakdown voltage (VBR), 10.5V working stand-off voltage (VWM), and 19.0V clamping voltage (VC) at 22A peak pulse current - designed for overvoltage protection in DC/DC converters and power adapters.
For engineers reviewing the P4SMA13C datasheet, P4SMA13C pinout, P4SMA13C application, or P4SMA13C equivalent, key selection criteria include clamping performance under 10/1000μs surge, low leakage (<1μA at VWM), ISO 7637-2 compliance, and DO-214AC thermal derating behavior up to +150°C junction temperature.
Technical Context
The P4SMA13C is a glass-passivated, single-die unidirectional TVS diode optimized for fast transient suppression in automotive and industrial power rails. Its sub-1ps response time and 400W peak pulse power rating (10/1000μs) enable robust protection against ESD, load dump, and inductive switching spikes.
It operates across –55°C to +150°C junction temperature range, features matte tin-plated leads compliant with J-STD-002 solderability, and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for the molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 11.7V / 14.3V at 1.0mA test current - defines reliable avalanche initiation window for predictable clamping onset |
| VWM | 10.5V - maximum continuous reverse voltage before significant leakage; sets safe operating margin below breakdown |
| VC @ IPPM | 19.0V at 22A (10/1000μs) - limits downstream voltage stress during worst-case transients |
| IR @ VWM | <1μA - ensures negligible standby power loss and signal integrity in high-impedance circuits |
| PPPM | 400W - sustains standardized 10/1000μs surge without failure; derates linearly above 25°C ambient |
| TJ max | +150°C - supports operation in enclosed power supplies and under-hood automotive environments |
| Package | DO-214AC (SMA) - industry-standard SMD outline enabling automated placement and 0.060g board weight |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; 2-terminal unidirectional configuration; matte tin-plated leads; polarity indicated by molded cathode band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / surge return node | Connected to protected circuit ground or low-side rail; carries full surge current during clamping |
| Cathode | Protected line input / high-side connection | Connected to power rail or signal line requiring overvoltage protection; reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable, repeatable avalanche characteristics and long-term reliability under repeated surge stress |
| ISO 7637-2 compliance (Pulse 1/2a/2b/3a/3b) | Validated for automotive power-line transient immunity without external filtering augmentation |
| Moisture sensitivity level 1 (J-STD-020) | Zero bake requirement prior to reflow; supports standard SMT assembly without moisture-related popcorning |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance mandates for industrial and consumer end equipment |
| Fast response time <1.0ps | Clamps transients before sensitive downstream ICs experience damaging voltage overshoot |
Applications
| Switching Mode Power Supply (SMPS) | On-board DC/DC Converter |
|---|---|
Use Scenario: Input stage of AC/DC adapter or isolated flyback converter exposed to line surges and ESD. IC Role / Device Role / Timing Role: Unidirectional TVS placed between primary-side bulk capacitor and ground to clamp positive-going transients. Use Value: Limits peak voltage to ≤19.0V during 400W 10/1000μs surges, protecting rectifier diodes and controller ICs. | Use Scenario: 12V-to-3.3V buck converter on an automotive body control module PCB. IC Role / Device Role / Timing Role: TVS connected across input rail to suppress load-dump-induced spikes from alternator regulation faults. Use Value: Withstands ≥22A peak impulse while maintaining VC ≤19.0V, preventing brownout or latch-up in downstream logic. |
| Lighting Application | Adapters |
Use Scenario: LED driver board in commercial downlight fixture subjected to lightning-induced surges on low-voltage DC bus. IC Role / Device Role / Timing Role: Bidirectional protection not required; unidirectional P4SMA13C guards 12V supply rail against positive transients only. Use Value: Sub-1μA leakage at 10.5V VWM avoids unnecessary power drain in always-on lighting systems. | Use Scenario: Universal input wall adapter (90–264V AC) with secondary-side 12V output feeding USB-PD controller. IC Role / Device Role / Timing Role: TVS placed on secondary-side output to absorb coupling transients from primary-side switching noise or ESD events. Use Value: DO-214AC footprint enables compact layout; 0.060g mass minimizes mechanical stress on solder joints during thermal cycling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600W rating, DO-214AA (SMB) package, 14.4–15.9V VBR, 11.1V VWM, 21.2V VC @ 28.3A | Higher power handling but larger footprint; better suited for higher-energy transients | Select when system-level surge testing exceeds 400W or when SMB pad layout already exists |
| 1.5SMC13A | 1500W rating, DO-214AB (SMC) package, 14.4–15.9V VBR, 11.1V VWM, 21.2V VC @ 71A | Triple power rating and larger thermal mass; requires more PCB area and higher cost | Choose for industrial motor drives or railway applications where multi-kA surge immunity is mandated |
Compared with SMBJ13A and 1.5SMC13A, the P4SMA13C offers optimal balance of 400W surge capability, minimal DO-214AC footprint, and low-leakage performance - making it ideal for space-constrained, cost-sensitive adapter and DC/DC designs where 22A peak impulse coverage is sufficient.

FAQ
What is the polarity configuration of the P4SMA13C?
The P4SMA13C is a unidirectional TVS diode with cathode band marking on the DO-214AC package. It conducts only during positive transients on the cathode side relative to anode, making it suitable for DC rail protection where polarity is fixed. This differs from bidirectional variants like P4SMA13CA, which protect both polarities.
Does the P4SMA13C meet automotive transient standards?
Yes, the P4SMA13C meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b requirements for automotive power line immunity. Its 400W peak pulse rating, 19.0V clamping voltage, and –55°C to +150°C operating range make it suitable for use in body electronics and infotainment power stages per OEM specifications.
What is the maximum clamping voltage of the P4SMA13C under surge conditions?
The P4SMA13C has a maximum clamping voltage (VC) of 19.0V at 22A peak pulse current using the standardized 10/1000μs waveform. This value is guaranteed across temperature and represents the highest voltage seen at the device terminals during worst-case transient events.
Can the P4SMA13C be used in bidirectional protection circuits?
No - the P4SMA13C is unidirectional and must be used with correct polarity orientation. For bidirectional protection, the P4SMA13CA variant (with "CA" suffix) is specified, offering symmetrical breakdown in both directions and identical VBR, VWM, and VC ratings for positive and negative transients.
What is the moisture sensitivity level (MSL) of the P4SMA13C?
The P4SMA13C has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and requires no baking prior to surface-mount reflow. This simplifies manufacturing and eliminates yield loss from moisture-related defects.
