Product details
Overview
P4SMA110CAHM3/I 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 94.0 V standoff voltage (VWM), 105–116 V breakdown voltage (VBR) at 1 mA, 152 V maximum clamping voltage (VC) at 2.0 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 μs waveform), suitable for protecting automotive sensor interfaces and industrial I/O lines.
For engineers reviewing the P4SMA110CAHM3/I datasheet, P4SMA110CAHM3/I pinout, P4SMA110CAHM3/I application, or P4SMA110CAHM3/I equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, halogen-free RoHS compliance, thermal resistance (RθJA = 120 °C/W), and compatibility with automated SMT assembly on standard 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity sensitivity. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast transient suppression with minimal voltage overshoot.
The device is rated for 150 °C maximum junction temperature and meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C). Its 400 W peak pulse power rating applies up to 91 V; above that, derated to 300 W - confirmed for P4SMA110CAHM3/I per datasheet note (1) and Table on page 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 94.0 V - Maximum continuous reverse voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown Voltage) | 105–116 V at 1 mA - Confirmed bidirectional breakdown range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 152 V at IPPM = 2.0 A (10/1000 μs) - Peak voltage seen by protected circuit during worst-case transient; critical for downstream IC survivability. |
| PPPM (Peak Pulse Power) | 400 W (≤91 V), 300 W (>91 V) - Validated energy-handling capacity under standardized surge waveform; determines robustness against lightning or ESD-like pulses. |
| ID (Max Reverse Leakage) | ≤1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | 150 °C - Enables reliable operation in under-hood automotive or industrial environments with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Certified for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110CA | Same VWM (94 V), same bidirectional structure, but SMB package (DO-214AA); 600 W PPPM rating (10/1000 μs) | Higher power handling but larger footprint (4.58 mm × 3.94 mm vs. SMA's 4.50 mm × 2.79 mm); less suitable for space-constrained automotive modules | Select SMBJ110CA only if board layout allows larger pad area and higher surge margin is required beyond 300–400 W. |
| 1.5KE110CA | Through-hole DO-201AE package; identical VWM/VBR/VC specs; 1500 W PPPM (10/1000 μs) | Not SMT-compatible; incompatible with automated assembly; used in legacy telecom or power supply designs where manual insertion is acceptable | Choose 1.5KE110CA only for prototyping, repair, or non-automated production where reflow compatibility is not required. |
Compared with SMBJ110CA and 1.5KE110CA, P4SMA110CAHM3/I offers optimal balance of AEC-Q101 qualification, halogen-free compliance, compact SMA footprint, and validated 300 W surge capability - making it the preferred choice for new automotive and industrial SMT designs requiring production scalability and regulatory alignment.

FAQ
What is the clamping voltage of P4SMA110CAHM3/I at its rated peak pulse current?
The P4SMA110CAHM3/I has a maximum clamping voltage (VC) of 152 V when subjected to a 10/1000 μs waveform at 2.0 A peak pulse current (IPPM). This value is measured under standardized test conditions per JEDEC and is guaranteed across the full operating temperature range, ensuring consistent protection behavior in automotive and industrial environments where P4SMA110CAHM3/I is deployed.
Is P4SMA110CAHM3/I suitable for automotive applications?
Yes, P4SMA110CAHM3/I is AEC-Q101 qualified (indicated by the HM3 suffix), meaning it has passed stress tests for temperature cycling, high-temperature reverse bias, and mechanical shock required for automotive use. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating further support deployment in engine control units, ADAS sensors, and body electronics where P4SMA110CAHM3/I provides certified transient immunity.
How does the bidirectional design of P4SMA110CAHM3/I affect its PCB layout?
The bidirectional nature of P4SMA110CAHM3/I eliminates polarity marking - both terminals are functionally identical, allowing placement without orientation checks during automated assembly. Layout requires symmetric 0.2" × 0.2" copper pads per terminal to maintain thermal performance and ensure specified 300 W surge capability; no cathode band alignment is needed, simplifying routing for differential or floating signal lines where P4SMA110CAHM3/I is applied.
What is the maximum reverse leakage current for P4SMA110CAHM3/I at its standoff voltage?
P4SMA110CAHM3/I exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 94.0 V standoff voltage (VWM), measured at 25 °C. This ultra-low leakage preserves signal fidelity in high-impedance sensor interfaces and minimizes quiescent power loss in battery-powered systems - a verified parameter documented in the Vishay P4SMA series datasheet Table on page 2 for all CA-suffix bidirectional variants including P4SMA110CAHM3/I.
Does P4SMA110CAHM3/I require special handling during reflow soldering?
No, P4SMA110CAHM3/I is rated MSL Level 1 per J-STD-020, permitting unlimited floor life and direct placement into standard lead-free reflow profiles with peak temperatures up to 260 °C. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the glass-passivated chip junction withstands thermal shock - eliminating bake steps or humidity-controlled storage typically needed for P4SMA110CAHM3/I in high-mix SMT lines.
