Product details
Overview
P4SMA13CH from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with 11.7V minimum breakdown voltage (VBR), 10.5V working stand-off voltage (VWM), and 19.0V maximum clamping voltage (VC) at 22A peak pulse current. It protects DC power rails in automotive-grade SMPS and on-board DC/DC converters against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA13CH datasheet, P4SMA13CH pinout, P4SMA13CH application, or P4SMA13CH equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, clamping performance under 10/1000μs surge, moisture sensitivity level (MSL 1), and bidirectional variant compatibility for robust automotive and industrial overvoltage protection design.
Technical Context
The P4SMA13CH employs a glass-passivated silicon junction optimized for fast transient response (<1.0 ps) and low leakage (<1 μA at VWM). Its unidirectional configuration provides asymmetric clamping-low forward voltage (3.5V @ 25A) during reverse surge conduction while blocking forward current beyond VF.
Designed per ANSI/IEEE C62.35, it sustains 400W peak pulse power (10/1000μs waveform) at 25°C with thermal derating above ambient, and operates across –55°C to +150°C junction temperature range. The device meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements for high-reliability PCB assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10.5 V - Maximum continuous reverse operating voltage before significant leakage begins; sets safe DC rail margin for 12V systems. |
| VBR (min/max) | 11.7 V / 14.3 V @ 1.0 mA - Confirmed breakdown threshold range ensures reliable turn-on during fast transients without premature conduction. |
| VC @ IPPM | 19.0 V @ 22 A - Clamped voltage during 10/1000μs surge defines maximum stress imposed on downstream ICs. |
| PPPM | 400 W - Peak pulse power handling capacity determines survivability against standardized automotive load-dump and inductive-switching events. |
| IR @ VWM | <1 μA - Ultra-low reverse leakage preserves battery life and avoids false triggering in always-on circuits. |
| TJ max | +150 °C - Enables operation in under-hood or high-power-density environments without thermal shutdown. |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Polarity is unidirectional: anode and cathode terminals defined by molded band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry terminal in forward bias | Connects to protected circuit ground or low-side return path; conducts during reverse-transient clamping. |
| Cathode (banded end) | Current exit terminal in forward bias; high-impedance node in normal operation | Connects to positive rail or signal line; establishes polarity-sensitive clamping direction for unidirectional protection. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress-test requirements including HTOL, TCT, and ESD, enabling use in engine control, body electronics, and ADAS modules. |
| Glass passivated junction | Enhances long-term reliability and stability of VBR and leakage under humidity, temperature cycling, and mechanical stress. |
| ISO 7637-2 compliance | Guarantees immunity to standardized automotive electrical transients (Pulse 1, 2a, 2b, 3a, 3b), eliminating need for additional filtering stages. |
| MSL Level 1 | Zero floor-life limitation enables indefinite storage and reflow without baking, simplifying SMT production planning. |
Applications
| Switching Mode Power Supply (SMPS) | Automotive On-Board DC/DC Converter |
|---|---|

Use Scenario: Constant-current LED driver board exposed to inductive kickback from relay-controlled ballast switching. IC Role / Device Role: Secondary-side TVS protecting LED driver IC and current-sense amplifier inputs. Use Value: Withstands repetitive 10/1000μs pulses up to 400W without parameter drift, ensuring consistent lumen output over 10-year service life. | Use Scenario: High-brightness LED matrix module connected directly to vehicle battery with no upstream fuse coordination. IC Role / Device Role: First-line transient suppression at connector interface, preceding EMI filter and DC/DC stage. Use Value: MSL Level 1 and AEC-Q101 qualification enable direct placement in lamp housing without conformal coating or derating penalties. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | 600W rating, SMB package (larger footprint), 14.4V VWM, 21.5V VC @ 27.8A | Higher power handling but requires PCB area increase; less suitable for ultra-compact layouts. | Select when surge energy exceeds 400W or when higher IPPM margin is required for extended lifetime in harsh environments. |
| P4SMA13A | Bidirectional variant (CH → AH suffix), same VWM/VBR/VC specs, identical DO-214AC package | Supports AC-coupled or floating signal lines where polarity reversal may occur (e.g., CAN bus stubs). | Choose for bidirectional protection needs without layout change-same footprint, same thermal profile, only marking and internal symmetry differ. |
Compared with SMBJ13A and P4SMA13A, the P4SMA13CH offers optimal balance of compact DO-214AC size, AEC-Q101 validation, and precise 10.5V–14.3V clamping window for 12V automotive subsystems-making it ideal for space-constrained, high-volume automotive and industrial power protection where unidirectional clamping suffices.

FAQ
What is the clamping voltage of P4SMA13CH and how is it measured?
The P4SMA13CH has a maximum clamping voltage (VC) of 19.0 V at 22 A peak pulse current, tested using the standardized 10/1000 μs double-exponential surge waveform per IEC 61000-4-5 and ANSI/IEEE C62.35. This value represents the upper voltage limit imposed on protected circuitry during worst-case transient events, ensuring downstream ICs remain within absolute maximum ratings. The P4SMA13CH maintains this clamping performance across its full operating temperature range.
Is P4SMA13CH suitable for automotive applications?
Yes, the P4SMA13CH is AEC-Q101 qualified and explicitly designed for automotive use. It meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements, supports junction temperatures from –55°C to +150°C, and carries MSL Level 1 rating for lead-free reflow. These attributes make the P4SMA13CH appropriate for engine control units, body control modules, and ADAS power supplies where reliability under harsh electrical and thermal conditions is mandatory.
How does P4SMA13CH differ from P4SMA13AH?
The P4SMA13CH is unidirectional, while P4SMA13AH is bidirectional-identical in VWM (11.1 V), VBR (12.4–13.7 V), and VC (18.2 V), but differing in internal junction symmetry and marking code (AUJ vs. AVJ). The P4SMA13CH provides polarity-specific clamping ideal for DC rails; P4SMA13AH supports AC or floating nodes. Both share DO-214AC packaging, AEC-Q101 qualification, and ISO 7637-2 compliance-enabling drop-in replacement only when polarity constraints allow.
What is the maximum peak pulse current rating for P4SMA13CH?
The P4SMA13CH is rated for a maximum peak impulse current (IPPM) of 22 A under the 10/1000 μs standard surge waveform. This rating is derived from its 400 W peak pulse power capability and 19.0 V clamping voltage (I = P/V). Derating applies above 25°C ambient per Figure 2 in the datasheet, with usable IPPM decreasing linearly to ~14 A at +100°C case temperature-critical for thermal design in enclosed automotive enclosures.
Does P4SMA13CH require special PCB layout considerations?
Yes-the P4SMA13CH benefits from low-inductance layout: short, wide traces between the device and protected node, minimal loop area, and direct connection to low-impedance ground plane. Its <1.0 ps response time means parasitic inductance dominates clamping performance; even 10 nH adds ~10 V overshoot. Use the recommended DO-214AC pad layout from TSC's Package Outline Drawing (Version A2102), avoid vias in current paths, and place the P4SMA13CH as close as possible to the connector or IC input it protects.
