Product details
Overview
P4SMA130CAHM3_A/I from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P4SMA series, designed for clamping voltage transients on signal or power lines. It features a 130 V standoff voltage (VWM), 149 V minimum breakdown voltage (VBR), 179 V maximum clamping voltage (VC) at 1.7 A peak pulse current, and 400 W peak pulse power rating with 10/1000 µs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the P4SMA130CAHM3_A/I datasheet, P4SMA130CAHM3_A/I pinout, P4SMA130CAHM3_A/I application, or P4SMA130CAHM3_A/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMA (DO-214AC) package compatibility, and thermal resistance (RθJA = 120 °C/W) for board-level surge protection design.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 µA at VWM), while the low incremental surge resistance supports rapid energy dissipation during ESD or lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow peak. Its 400 W peak pulse power (derated to 300 W above 91 V) and 1.7 A IPPM are specified under standardized 10/1000 µs waveform conditions on 5.0 mm × 5.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 111 V - Maximum continuous reverse working voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 124–137 V at 1 mA - Confirmed avalanche onset range; ensures predictable clamping initiation across production lot. |
| VC (Clamping Voltage) | 179 V at IPPM = 1.7 A - Peak voltage seen by protected circuit during transient; directly limits stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W (10/1000 µs) - Energy-handling capacity for single transient events; derates to 300 W above 91 V VWM. |
| ID (Reverse Leakage) | <1 µA at VWM - Minimal standby current draw; preserves signal integrity and battery life in low-power systems. |
| TJ max. | 150 °C - Maximum allowable junction temperature; supports operation in under-hood automotive and industrial ambient environments. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock testing. |

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 (111 V) and VC (179 V), but SMB package (DO-214AA); 600 W PPPM rating; RθJA = 100 °C/W. | Higher power handling and lower thermal resistance; requires larger PCB pad area than SMA. | Select when higher surge margin or improved thermal performance is required and board space permits SMB footprint. |
| 1.5KE130CA | Through-hole DO-201 package; 130 V VWM; 179 V VC; 1500 W PPPM; RθJA = 15 °C/W (with heatsink). | Designed for high-energy industrial mains protection; not surface-mount compatible. | Choose only for legacy through-hole designs or where extreme energy absorption (>1 kW) is mandated and automated assembly is not required. |
Compared with SMBJ130CA and 1.5KE130CA, P4SMA130CAHM3_A/I offers optimal balance of AEC-Q101 qualification, compact SMA footprint, and verified 400 W surge capability - making it preferred for space-constrained automotive and industrial SMT assemblies where reliability and manufacturability are jointly prioritized.

FAQ
What does the "CA" suffix indicate in P4SMA130CAHM3_A/I?
The "CA" suffix in P4SMA130CAHM3_A/I denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P4SMA130A), it has no polarity marking and functions identically in either direction - essential for protecting AC-coupled or floating signal paths where voltage polarity is undefined or reversible.
Is P4SMA130CAHM3_A/I qualified for automotive use?
Yes, P4SMA130CAHM3_A/I is AEC-Q101 qualified, as confirmed by Vishay's ordering code structure ("HM3" indicates halogen-free, RoHS-compliant, and AEC-Q101 qualified). This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing - validating its suitability for under-hood and cabin-mounted automotive electronics.
What is the maximum clamping voltage of P4SMA130CAHM3_A/I and under what test condition?
The maximum clamping voltage (VC) of P4SMA130CAHM3_A/I is 179 V, measured at a peak pulse current (IPPM) of 1.7 A using the standardized 10/1000 µs double-exponential waveform. This value represents the worst-case voltage imposed on the protected circuit during a transient event and is guaranteed across the full operating temperature range per Vishay's datasheet specifications.
How does the SMA (DO-214AC) package of P4SMA130CAHM3_A/I affect thermal performance?
The SMA (DO-214AC) package of P4SMA130CAHM3_A/I 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 standard FR-4 PCB layout; reducing pad size or omitting thermal vias increases junction temperature - potentially derating peak pulse power in sustained surge scenarios.
Can P4SMA130CAHM3_A/I replace unidirectional TVS diodes in existing designs?
No - P4SMA130CAHM3_A/I is strictly bidirectional and lacks polarity marking; it cannot substitute for unidirectional TVS diodes (e.g., P4SMA130A) in DC-biased circuits where forward conduction must be blocked. Attempting replacement may cause unintended conduction or failed clamping. Use only where bidirectional symmetry is required, such as across differential pairs or AC signal lines.
