Product details
Overview
P4SMA130H from Taiwan Semiconductor is a unidirectional 400W surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, with a working stand-off voltage of 105 V, breakdown voltage range 117–143 V at 1 mA, and clamping voltage of 187 V at 2.2 A (10/1000 μs waveform), used for overvoltage protection in automotive DC/DC converters and industrial power supplies.
For engineers reviewing the P4SMA130H datasheet, P4SMA130H pinout, P4SMA130H application, or P4SMA130H equivalent, key selection criteria include peak pulse power rating (400 W), clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, AEC-Q101 qualification, and unidirectional polarity marking on DO-214AC body.
Technical Context
The P4SMA130H operates as a unidirectional avalanche diode, activated when reverse voltage exceeds its 117–143 V breakdown threshold. It delivers 400 W peak pulse power handling per 10/1000 μs waveform and maintains <1 μA leakage at 105 V stand-off voltage.
Its glass-passivated junction ensures stable breakdown characteristics across -55°C to +150°C operating temperature, and it meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 requirements for automated SMT assembly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 105 V - Maximum continuous reverse operating voltage before significant leakage begins |
| VBR @ IT=1 mA | 117–143 V - Confirmed breakdown voltage window ensuring reliable turn-on margin above system rail |
| VC @ IPPM=2.2 A | 187 V - Clamped voltage during 10/1000 μs surge, limiting downstream IC stress |
| PPPM | 400 W - Peak pulse power dissipation capability per single non-repetitive transient |
| TJ max | +150 °C - Maximum junction temperature enabling use in under-hood automotive environments |
| IR @ VWM | <1 μA - Ultra-low leakage preserves efficiency in high-impedance bias networks |
| Response time | <1.0 ps - Sub-picosecond avalanche response ensures protection before sensitive circuitry fails |

Applications
| Automotive DC/DC Converter Protection | Industrial SMPS Input Stage |
|---|---|
Use Scenario: Protects 12 V–48 V input rails in automotive buck/boost converters against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between input rail and chassis ground to clamp surges before they reach controller ICs and MOSFETs. Use Value: Withstands ISO 7637-2 Pulse 1 (−150 V, 50 ms) and clamps to ≤187 V, preserving gate oxide integrity of downstream power stages. | Use Scenario: Shields AC-DC and isolated DC/DC converter primary-side rectifiers and controllers from lightning-induced and switching-induced transients. IC Role / Device Role / Timing Role: Mounted across bulk capacitor or bridge rectifier output to absorb repetitive line surges without degradation. Use Value: 400 W peak power rating and <1 μA leakage at 105 V enable high-efficiency operation while meeting IEC 61000-4-5 Level 3 immunity. |
| On-Board Charger (OBC) Interface | LED Driver Power Input |
Use Scenario: Safeguards bidirectional OBC control logic and communication lines during EV charging cycles with grid-side voltage fluctuations. IC Role / Device Role / Timing Role: Applied at HV/LV interface points (e.g., CAN bus power rails or auxiliary supply inputs) to suppress coupled noise and fast transients. Use Value: Sub-1 ps response time and AEC-Q101 qualification ensure robust operation in harsh vehicle electrical environments. | Use Scenario: Guards constant-current LED driver ICs and MOSFETs against inductive kickback from magnetic components and hot-plug events. IC Role / Device Role / Timing Role: Placed across input capacitors to limit transient voltage overshoot during startup and fault conditions. Use Value: 187 V clamping at 2.2 A prevents latch-up in 100 V-rated driver ICs and extends LED module lifetime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 600 W rating, DO-214AA (SMB) package, 130 V nominal VBR, slightly higher VC (219 V) | Higher power headroom but larger footprint; better suited for systems requiring >400 W margin | Select SMBJ130A when board space allows and peak surge energy exceeds 400 W capability of P4SMA130H |
| 1.5SMC130A | 1500 W rating, DO-214AB (SMC) package, same VBR range, VC = 219 V, higher IPPM | Designed for heavy-duty industrial transients; not AEC-Q101 qualified | Choose 1.5SMC130A for non-automotive applications needing higher single-pulse energy absorption |
Compared with SMBJ130A and 1.5SMC130A, the P4SMA130H offers optimal balance of AEC-Q101 compliance, compact DO-214AC footprint, and precise 105 V stand-off for 12 V–48 V automotive subsystems - making it preferred where space, qualification, and clamping voltage tightness are critical.

FAQ
Is P4SMA130H unidirectional or bidirectional?
The P4SMA130H is a unidirectional TVS diode, indicated by the absence of "A" in its suffix and confirmed by its cathode band marking and single-polarity clamping behavior. It protects against reverse-polarity transients only - unlike bidirectional variants such as P4SMA130AH, which suppress surges in both directions.
What is the clamping voltage of P4SMA130H at rated peak current?
The P4SMA130H has a maximum clamping voltage (VC) of 187 V at 2.2 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events.
Does P4SMA130H meet automotive qualification standards?
Yes, the P4SMA130H is AEC-Q101 qualified and meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements. Its construction - including glass-passivated junction, MSL Level 1 rating, and JESD201 Class 2 whisker resistance - supports deployment in automotive powertrain and body electronics.
What package type does P4SMA130H use, and is it RoHS compliant?
The P4SMA130H uses the DO-214AC (SMA) surface-mount package with matte tin-plated leads and UL 94V-0 molding compound. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, supporting lead-free reflow assembly and environmental compliance programs.
How does P4SMA130H compare to P4SMA130AH?
The P4SMA130AH is the bidirectional variant with identical VWM (111 V), VBR (124–137 V), and PPPM (400 W), but clamps in both polarities. The P4SMA130H offers tighter VBR tolerance (117–143 V) and lower VC (187 V vs. 179 V), making it preferable for unidirectional 12 V–48 V rail protection where polarity is fixed.
