Product details
Overview
P4SMA130AH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, rated for 400W peak pulse power, 124–137V breakdown voltage (VBR), and 111V working stand-off voltage (VWM), designed to protect DC/DC converters and automotive power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P4SMA130AH datasheet, P4SMA130AH pinout, P4SMA130AH application, or P4SMA130AH equivalent, key selection criteria include clamping voltage (179V @ 2.3A), low leakage (<1µA @ 111V), AEC-Q101 qualification, and DO-214AC thermal and mechanical compatibility with automated SMT assembly.
Technical Context
The P4SMA130AH operates as a unidirectional avalanche diode with glass-passivated junction, delivering fast response (<1.0ps) and stable clamping under 10/1000μs surge waveforms. Its VBR tolerance (±5.5%) and temperature coefficient (0.107%/°C) ensure predictable turn-on across -55°C to +150°C junction range.
It meets ISO 7637-2 immunity requirements for automotive electronics and supports bidirectional variants via CAH suffix (e.g., P4SMA130CAH). The device is not intended for AC line protection or repetitive surge environments exceeding its 400W non-repetitive rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT=1mA | 124–137V - defines precise avalanche initiation window for reliable overvoltage triggering |
| VWM | 111V - maximum continuous reverse voltage before leakage exceeds 1µA, sets system operating margin |
| VC @ IPPM=2.3A | 179V - clamped voltage during 10/1000μs surge, determines protected circuit's voltage stress limit |
| PPPM | 400W - peak pulse power handling per single transient, defines survivability against ISO 7637-2 pulses |
| IR @ VWM | <1µA - ultra-low reverse leakage ensures minimal standby power loss in high-impedance bias networks |
| TJ Range | -55°C to +150°C - enables deployment in under-hood automotive and industrial power supply environments |
Pinout & Package
DO-214AC (SMA) surface-mount package with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; weight ≈ 0.060g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-impedance return path; carries full surge current during clamping |
| Cathode | Protected line input | Connected to rail being safeguarded (e.g., 110V DC bus); voltage referenced to anode during conduction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD robustness per stress test plan |
| Glass passivated junction | Enhances long-term stability and moisture resistance vs. epoxy-passivated alternatives, critical for under-hood longevity |
| Clamping ratio (VC/VBR) | ~1.42 - tight ratio ensures minimal overvoltage overshoot during transient suppression |
| Moisture sensitivity level | MSL Level 1 (per J-STD-020) - allows unlimited floor life and standard reflow without baking |
Applications
| Automotive Power Rail Protection | Industrial DC/DC Converter Input |
|---|---|
Use Scenario: Protecting 110V battery-fed control modules in passenger vehicles against load dump and alternator switching transients. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between battery rail and DC/DC input, clamping surges within 1ps to prevent upstream regulator damage. Use Value: With 179V clamping at 2.3A and AEC-Q101 qualification, P4SMA130AH ensures compliance with ISO 7637-2 Pulse 5a while maintaining <1µA leakage at nominal 111V operation. | Use Scenario: Safeguarding isolated 110V-to-12V DC/DC converter inputs in factory automation PLCs exposed to inductive switching noise. IC Role / Device Role / Timing Role: Standoff protector on primary-side input, absorbing repetitive 10/1000μs transients induced by relay coils and motor drivers. Use Value: 400W peak power rating and -55°C to +150°C operation allow sustained protection in unventilated enclosures where ambient exceeds 85°C. |
| Telecom Power Supply Clamp | Energy Meter Voltage Rail Protection |
Use Scenario: Clamping induced surges on 110V DC telecom rectifier outputs feeding base station backplanes. IC Role / Device Role / Timing Role: Primary-level transient suppressor mounted directly at rectifier output, shunting energy before distribution to sensitive logic rails. Use Value: 124–137V VBR window aligns with 110V nominal systems, enabling precise threshold activation without false triggering during ripple or brownout events. | Use Scenario: Protecting microcontroller supply rails in smart electricity meters connected to 110V utility lines subject to lightning-induced coupling. IC Role / Device Role / Timing Role: Secondary-stage TVS on meter's internal 110V auxiliary supply, downstream of bulk filtering but upstream of LDO regulators. Use Value: DO-214AC footprint enables compact layout; 179V clamping ensures MCU IO remains below absolute maximum ratings even during worst-case 1kV/0.5μs coupled transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Same VWM (111V), higher PPPM (600W), DO-214AA package (larger footprint) | Preferred where higher surge margin is required and PCB space permits larger SMA variant | Select SMBJ130A if system-level testing shows >400W surge exposure or if thermal derating headroom is needed |
| 1.5SMC130A | Same VBR/VWM, identical PPPM (400W), DO-214AB (SMC) package (3.6×7.1mm vs. SMA's 2.8×4.6mm) | Used where higher thermal mass is beneficial and board real estate allows larger body size | Choose 1.5SMC130A when junction temperature rise must be minimized in high-duty-cycle transient environments |
Compared with SMBJ130A and 1.5SMC130A, the P4SMA130AH offers the smallest footprint (DO-214AC) while maintaining identical electrical specs for 110V systems, making it optimal for space-constrained automotive and portable industrial modules where layout density is critical.

FAQ
What is the clamping voltage of the P4SMA130AH under standard 10/1000μs surge conditions?
The P4SMA130AH has a maximum clamping voltage (VC) of 179V when subjected to a 10/1000μs waveform with peak impulse current (IPPM) of 2.3A. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on the protected circuit during transient events. The P4SMA130AH maintains this clamping performance across its full operating temperature range of -55°C to +150°C.
Is the P4SMA130AH suitable for bidirectional transient protection?
No, the P4SMA130AH is a unidirectional TVS diode intended for DC rail protection only. For bidirectional applications, Taiwan Semiconductor specifies the P4SMA130CAH variant (with "CAH" suffix), which provides symmetrical clamping in both polarities. Using the P4SMA130AH in AC or reverse-biased configurations may result in forward conduction failure or permanent damage.
Does the P4SMA130AH require special handling or baking prior to reflow soldering?
No, the P4SMA130AH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging or pre-reflow baking. Its DO-214AC (SMA) package uses matte tin-plated leads compliant with J-STD-002, supporting standard lead-free reflow profiles without dewetting or voiding concerns.
How does the P4SMA130AH compare to the P4SMA130H in terms of breakdown voltage tolerance?
The P4SMA130AH has a tighter VBR range of 124–137V (±5.5%), whereas the P4SMA130H spans 117–143V (±11.3%). This narrower tolerance improves design predictability in precision-clamp applications such as regulated 110V DC systems where consistent turn-on behavior minimizes risk of false triggering or inadequate protection.
Can the P4SMA130AH be used in place of a P4SMA120AH for 110V rail protection?
Substituting P4SMA130AH for P4SMA120AH is not recommended without circuit validation: the P4SMA130AH has higher VWM (111V vs. 102V) and VBR (124–137V vs. 114–126V), reducing margin against normal operating voltage excursions. While both meet ISO 7637-2, the P4SMA130AH's higher thresholds may delay clamping during marginal transients, potentially exposing downstream components to overvoltage.
