Overview
P4SMA130CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on signal and power lines. It features a 111 V standoff voltage (VWM), 124–137 V breakdown voltage (VBR) at 1 mA, 179 V maximum clamping voltage (VC) at 1.7 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform), suitable for automotive-grade ESD and surge protection in sensor interfaces and power rails.
For engineers reviewing the P4SMA130CAHM3/H datasheet, P4SMA130CAHM3/H pinout, P4SMA130CAHM3/H application, or P4SMA130CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, low thermal resistance (RθJL = 30 °C/W), and compatibility with automated SMT assembly on standard PCB copper pads.
Technical Context
The P4SMA130CAHM3/H operates as a bidirectional avalanche diode, symmetrically clamping transient overvoltages in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMA package supports high surge current handling with minimal parasitic inductance.
Rated for 150 °C maximum junction temperature and MSL Level 1 moisture sensitivity, it delivers 400 W peak pulse power (derated to 300 W above 91 V), with 1.7 A IPPM at VC = 179 V under 10/1000 µs waveform - validated using 0.2" × 0.2" copper pads per terminal per JEDEC standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; 600 W PPPM rating; RθJA = 100 °C/W vs. 120 °C/W for P4SMA130CAHM3/H. | Higher power handling suits higher-energy surges; larger footprint requires PCB redesign. | Select when surge energy exceeds 400 W or thermal management demands lower junction-to-ambient resistance. |
| 1.5KE130CA | Through-hole DO-201 package; 1500 W PPPM; higher VF and slower response due to wirebond construction; not AEC-Q101 qualified. | Used in legacy industrial power supplies; incompatible with automated SMT and automotive qualification requirements. | Choose only for cost-sensitive, non-automotive through-hole designs where board space and qualification are secondary. |
Compared with SMBJ130CA and 1.5KE130CA, the P4SMA130CAHM3/H offers optimal balance of AEC-Q101 compliance, SMT compatibility, and verified 400 W surge capability in the smallest standardized surface-mount TVS outline - making it preferred for new automotive and space-constrained industrial designs.

FAQ
What does the "HM3" suffix indicate in P4SMA130CAHM3/H?
The "HM3" suffix in P4SMA130CAHM3/H denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification. The "H" indicates 7-inch tape-and-reel packaging (1800 units per reel), and "M3" confirms compliance with JESD201 Class 2 whisker resistance and UL 94 V-0 flammability rating - all verified per Vishay document 88367 revision 09-Jan-2024. This makes P4SMA130CAHM3/H suitable for automotive production environments.
Is P4SMA130CAHM3/H unidirectional or bidirectional?
P4SMA130CAHM3/H is a bidirectional Transient Voltage Suppressor, as confirmed by the "CA" suffix in its part number and explicit documentation stating "Electrical characteristics apply in both directions." Unlike unidirectional variants (e.g., P4SMA130A), it has no cathode band marking and provides symmetrical clamping for AC-coupled or floating signal paths - a key design feature of the P4SMA130CAHM3/H.
What is the maximum clamping voltage of P4SMA130CAHM3/H under surge conditions?
The maximum clamping voltage (VC) of P4SMA130CAHM3/H is 179 V, measured at 1.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is specified in the Electrical Characteristics table on page 2 of Vishay document 88367 and represents the worst-case voltage imposed on the protected circuit during a defined surge event - a critical parameter for validating system-level overvoltage immunity of the P4SMA130CAHM3/H.
Does P4SMA130CAHM3/H require special PCB layout considerations?
Yes - P4SMA130CAHM3/H must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve its rated 400 W peak pulse power, as specified in the "Maximum Ratings" table and Figure 1 of Vishay document 88367. Smaller pads cause thermal derating and reduced surge capability. Additionally, short, direct traces to protected nodes minimize inductance and preserve sub-1 ns response - essential for effective transient suppression using the P4SMA130CAHM3/H.
How does P4SMA130CAHM3/H differ from P4SMA130A?
P4SMA130CAHM3/H is bidirectional with AEC-Q101 qualification, halogen-free materials, and HM3 packaging, whereas P4SMA130A is unidirectional, commercial-grade (no automotive qualification), and lacks the "HM3" suffix. Their electrical parameters differ: P4SMA130CAHM3/H has VWM = 111 V and VBR = 124–137 V, while P4SMA130A has VWM = 111 V but VBR = 124–137 V only in forward direction - confirming P4SMA130CAHM3/H's symmetrical behavior is intrinsic to its CA designation and construction.
