Overview
P4SMA130AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 130 V standoff voltage (VWM), 124–137 V breakdown voltage (VBR) at 1 mA test current, and 179 V maximum clamping voltage (VC) at 1.7 A peak pulse current (IPPM), delivering 400 W peak pulse power with 10/1000 µs waveform for surge protection of power rails and signal lines in automotive and industrial electronics.
For engineers reviewing the P4SMA130AHM3_A/H datasheet, P4SMA130AHM3_A/H pinout, P4SMA130AHM3_A/H application, or P4SMA130AHM3_A/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data, clamping performance under standardized transients, and real-world design context for ESD and lightning-induced surge mitigation in DC power inputs and sensor interfaces.
Technical Context
The P4SMA130AHM3_A/H operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a sharp reverse-biased breakdown region with ±5% VBR tolerance and 0.107 %/°C temperature coefficient.
Designed for surface-mount assembly on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, it supports repetitive surge duty cycles up to 0.01% and meets MSL Level 1 per J-STD-020 with 260 °C peak reflow profile. It is halogen-free, RoHS-compliant, and AEC-Q101 qualified for automotive-grade reliability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A | Same VWM (111 V), VBR (124–137 V), and VC (179 V); 400 W rating; but not AEC-Q101 qualified and uses standard RoHS (not halogen-free) construction. | Limited to commercial/industrial use; unsuitable for automotive production where AEC-Q101 and halogen-free compliance are mandatory. | Select SMAJ130A only if AEC-Q101 and halogen-free requirements are absent and cost sensitivity outweighs long-term reliability validation needs. |
| 1.5SMC130A | Higher package thermal resistance (RθJA ≈ 150 °C/W vs. 120 °C/W); same electrical specs but larger SMC (DO-214AB) footprint and 1.5 kW peak power rating (over-specified for most 400 W use cases). | Requires PCB redesign due to larger 7.11 mm × 6.22 mm SMC outline versus 4.50 mm × 3.99 mm SMA; adds unnecessary board area and cost. | Choose 1.5SMC130A only when higher single-pulse energy margin (>400 W) is required and layout allows larger package; otherwise P4SMA130AHM3_A/H offers optimal size/performance balance. |
Compared with SMAJ130A and 1.5SMC130A, P4SMA130AHM3_A/H uniquely combines AEC-Q101 qualification, halogen-free materials, SMA footprint efficiency, and verified 400 W clamping performance-making it the preferred choice for space-constrained, automotive-grade, and environmentally compliant designs.

FAQ
What is the clamping voltage of P4SMA130AHM3_A/H at its rated peak pulse current?
The P4SMA130AHM3_A/H has a maximum clamping voltage (VC) of 179 V at its specified peak pulse current (IPPM) of 1.7 A under the standard 10/1000 µs waveform. This value is measured per Figure 1 in Vishay document 88367 and defines the upper voltage limit imposed on protected circuitry during surge events. The P4SMA130AHM3_A/H maintains this clamping performance across its qualified operating temperature range and is validated for repetitive surge duty cycles up to 0.01%.
Is P4SMA130AHM3_A/H suitable for automotive applications?
Yes, P4SMA130AHM3_A/H is AEC-Q101 qualified and designated with the "HM3" suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It undergoes stress testing for temperature cycling, humidity, mechanical shock, and surge endurance per AEC-Q101 Rev D. The P4SMA130AHM3_A/H is explicitly recommended for body electronics, infotainment power rails, and sensor interface protection where automotive reliability standards apply.
What does the "_A/H" suffix mean in P4SMA130AHM3_A/H?
The "_A/H" suffix in P4SMA130AHM3_A/H indicates revision level "A" and packaging in 7-inch diameter plastic tape and reel (code "H") with 1800 units per reel. Per Vishay's ordering information table (page 3), "H" denotes the 7" reel format, while "A" reflects the revision of the AEC-Q101 qualified variant within the P4SMA130A family. The P4SMA130AHM3_A/H is functionally identical to other HM3 variants except for this packaging and revision designation.
How does P4SMA130AHM3_A/H compare to bidirectional TVS diodes like P4SMA130CA?
P4SMA130AHM3_A/H is unidirectional and intended for DC line protection where polarity is fixed (e.g., +12 V to ground), offering lower leakage (<1 µA at 111 V) and tighter VBR tolerance. In contrast, P4SMA130CA is bidirectional, suited for AC or polarity-agnostic signals, but exhibits higher reverse leakage (doubled per note 4 for VR ≤ 10 V-though not applicable here) and symmetric clamping. The P4SMA130AHM3_A/H cannot replace P4SMA130CA in AC-coupled applications without circuit redesign.
What is the thermal resistance of P4SMA130AHM3_A/H, and how does it affect layout?
The P4SMA130AHM3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's mechanical drawing. To maintain safe junction temperatures under repetitive surges, PCB layout must allocate adequate copper area and avoid thermal bottlenecks-especially critical in enclosed automotive enclosures where ambient can exceed 85 °C. The P4SMA130AHM3_A/H's RθJA directly impacts maximum allowable average power dissipation in continuous operation scenarios.
