Product details
Overview
P4SMA13CAH from Taiwan Semiconductor is a bidirectional 400W transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with breakdown voltage 12.4–13.7 V at 1 mA test current, working stand-off voltage 11.1 V, clamping voltage 18.2 V at 23 A peak impulse current, and AEC-Q101 qualification for automotive-grade surge protection in DC/DC converters.
For engineers reviewing the P4SMA13CAH datasheet, P4SMA13CAH pinout, P4SMA13CAH application, or P4SMA13CAH equivalent, this page delivers verified electrical specs, bidirectional TVS behavior, ISO 7637-2 pulse compliance, moisture sensitivity level 1 handling guidance, and real-world clamping performance under 10/1000 μs transients - critical for robust power rail protection design.
Technical Context
The P4SMA13CAH is a glass-passivated, bipolar junction TVS diode designed for bidirectional transient suppression on signal or power lines. Its symmetrical breakdown (12.4–13.7 V) and clamping (18.2 V @ 23 A) ensure equal protection against positive and negative polarity surges without external polarity management.
It operates across –55°C to +150°C junction temperature, meets JESD201 Class 2 whisker resistance, and complies with ISO 7637-2 Pulse 1/2a/2b/3a/3b waveforms - confirming suitability for automotive load-dump and inductive-switching immunity testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR min/max | 12.4 V / 13.7 V at 1 mA - defines minimum and maximum voltage at which device enters avalanche conduction during surge events |
| VWM | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 1 µA; sets safe DC bias margin |
| VC @ IPPM | 18.2 V at 23 A (10/1000 μs) - clamped voltage seen by protected circuit during worst-case transient |
| PPPM | 400 W - peak pulse power handling capability under standardized surge waveform |
| IR @ VWM | <1 µA - ultra-low leakage ensures minimal standby power loss and signal integrity in high-impedance circuits |
| TJ max | +150 °C - enables operation in under-hood automotive environments and thermally constrained PCB layouts |
| Package | DO-214AC (SMA) - surface-mount outline with 0.060 g mass, UL 94V-0 molding, and matte tin-plated leads per J-STD-002 |
Pinout & Package
DO-214AC (SMA) package: molded plastic case with cathode band marking; bidirectional configuration means no anode/cathode polarity - terminals are symmetric and interchangeable for AC or differential line protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Surge input/output node | Connects to line under protection; identical function to Terminal 2 due to bidirectional symmetry |
| Terminal 2 | Surge input/output node | Connects to return or reference plane; electrically equivalent to Terminal 1 in CAH-series devices |
Key Features
| Feature | Design Value |
|---|---|

| ISO 7637-2 compliance | Withstands Pulse 1 (inductive load dump), Pulse 2a/2b (switching transients), and Pulse 3a/3b (line impedance coupling) without degradation |
| Fast response time | <1.0 ps - ensures clamping activation prior to sensitive downstream IC damage during nanosecond-scale ESD or lightning-induced edges |
| Moisture sensitivity level 1 | No floor life limitation or bake requirement before reflow - simplifies SMT assembly planning and inventory control |
| Halogen-free & RoHS | Complies with IEC 61249-2-21 and EU RoHS Directive - meets environmental compliance for global automotive and industrial shipments |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver power rails from load-dump spikes and alternator ripple in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surge energy before reaching LDOs and logic ICs. Use Value: Clamps 23 A transients to ≤18.2 V, preventing overvoltage damage to 3.3 V/5 V logic while maintaining AEC-Q101 reliability certification. | Use Scenario: Shields 24 V DC digital input channels from field-wiring induced surges in factory automation cabinets. IC Role / Device Role / Timing Role: Front-end transient suppressor on optocoupler input side, absorbing repetitive switching noise from solenoid valves and contactors. Use Value: 400 W peak power rating sustains repeated 10/1000 μs pulses without parameter shift; <1 µA leakage avoids false triggering of high-impedance sensing circuits. |
| LED Driver Power Supply | On-Board Charger (OBC) Auxiliary Rail |
Use Scenario: Safeguards constant-current LED driver ICs from flyback voltage spikes generated by inductive ballast switching. IC Role / Device Role / Timing Role: Parallel-connected TVS across primary-side MOSFET drain-source or secondary-side rectifier output. Use Value: 11.1 V working voltage aligns with 12 V nominal supply; 18.2 V clamping prevents latch-up in driver ICs rated for ≤20 V absolute maximum. | Use Scenario: Protects 12 V auxiliary power rail in EV on-board chargers from battery reversal and jump-start transients. IC Role / Device Role / Timing Role: Bidirectional clamp between AUX+ and AUX− lines, referenced to chassis ground via low-inductance layout. Use Value: AEC-Q101 qualification and –55°C to +150°C operation ensure reliability across full EV thermal envelope; DO-214AC footprint allows automated placement in high-volume OBC production. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | 600 W peak power, SMB package (larger footprint), same VBR range and bidirectional configuration | Better suited for higher-energy transients; requires PCB area increase and may need layout revision | Select when system-level surge testing exceeds 400 W but board space permits SMB outline |
| 1.5SMC13CA | 1500 W peak power, SMC package (3.5 mm × 7.0 mm), higher IPPM (103 A), same VWM/VC specs | Targeted at heavy-duty industrial equipment with IEC 61000-4-5 Level 4 immunity requirements | Choose for applications requiring >400 W margin or legacy SMC-compatible designs |
Compared with SMBJ13CA and 1.5SMC13CA, the P4SMA13CAH offers optimal balance of AEC-Q101 compliance, DO-214AC compactness, and 400 W surge capacity - making it preferred for space-constrained automotive modules where 10/1000 μs pulse energy falls within its derated PPPM envelope.

FAQ
What does the "CAH" suffix indicate in P4SMA13CAH?
The "CAH" suffix denotes a bidirectional configuration with AEC-Q101 qualification and halogen-free construction. Unlike unidirectional "H" variants, P4SMA13CAH provides symmetrical clamping for both polarities - essential for protecting AC-coupled or floating differential lines without polarity concerns. This exact specification applies only to the P4SMA13CAH part number per TSC's ordering code documentation.
Is P4SMA13CAH suitable for ISO 7637-2 Pulse 5a (load dump) protection?
No - P4SMA13CAH is rated for ISO 7637-2 Pulses 1, 2a, 2b, 3a, and 3b only. Pulse 5a (load dump) requires higher energy handling (≥1000 W) and specialized TVS or suppressor designs. The P4SMA13CAH's 400 W peak power rating and 18.2 V clamping voltage are insufficient for sustained 12 V system load-dump events; use dedicated load-dump suppressors like TSDA12C or SMAJ15A for that application.
What is the maximum clamping voltage of P4SMA13CAH under standard test conditions?
The maximum clamping voltage of P4SMA13CAH is 18.2 V at 23 A peak impulse current using the 10/1000 μs double-exponential waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in TSC's Electrical Specifications table for the P4SMA13CAH part number. It represents the highest voltage imposed on the protected circuit during worst-case transient conduction.
Does P4SMA13CAH require special handling for moisture sensitivity?
No - P4SMA13CAH has Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions without baking or dry-pack requirements. This eliminates floor-life tracking and pre-reflow bake steps in SMT assembly, reducing manufacturing overhead and supporting just-in-time production for P4SMA13CAH-based designs.
How does the glass passivation in P4SMA13CAH improve long-term reliability?
Glass passivation in P4SMA13CAH protects the silicon junction from environmental contaminants, humidity ingress, and electrochemical migration - significantly extending operational life in humid or chemically aggressive environments. This process is explicitly cited in TSC's features list and contributes to the device's AEC-Q101 qualification and 150°C maximum junction temperature rating, ensuring stable VBR and leakage performance over 15+ years in automotive applications.
