Product details
Overview
P4SMA62CA-M3/61 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, rated for 62 V breakdown voltage (VBR = 58.9–65.1 V at IT = 1.0 mA), 85.0 V maximum clamping voltage (VC) at 4.7 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs waveform). It protects signal lines and power rails in sensor interfaces, industrial control inputs, and telecom line cards against ESD and inductive switching transients.
For engineers reviewing the P4SMA62CA-M3/61 datasheet, P4SMA62CA-M3/61 pinout, P4SMA62CA-M3/61 application, or P4SMA62CA-M3/61 equivalent, this device delivers verified bidirectional clamping with low incremental surge resistance, AEC-Q101 qualification (via HM3 suffix), halogen-free RoHS compliance, and MSL Level 1 moisture sensitivity - critical for automotive-grade board-level surge protection design and high-reliability industrial PCB layouts.
Technical Context
The P4SMA62CA-M3/61 operates as a bidirectional avalanche diode, symmetrically clamping voltage surges above ±62 V in both polarities without polarity marking. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5).
Thermally, it features RθJA = 120 °C/W (junction-to-ambient, on 0.2" × 0.2" copper pads) and TJ(max) = +150 °C, supporting operation in ambient temperatures up to +125 °C when derated per Fig. 2. The 3.3 W steady-state power dissipation (PD) and 400 W peak pulse rating (with 0.01% duty cycle) define its robust transient handling capability under repetitive surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V at IT = 1.0 mA - defines precise bidirectional avalanche onset threshold for reliable overvoltage triggering |
| VWM | 53.0 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA, setting safe operating margin below VBR |
| VC @ IPPM | 85.0 V at 4.7 A - clamped voltage during 10/1000 µs surge, directly determining protected circuit's maximum stress level |
| PPPM | 400 W - peak transient power absorption capacity, enabling protection against high-energy inductive spikes in 24 V/48 V systems |
| IPPM | 4.7 A - maximum non-repetitive surge current supported, defining minimum trace width and layout clearance requirements |
| TJ(max) | +150 °C - maximum junction temperature, allowing use in under-hood automotive or enclosed industrial enclosures |
| Package | SMA (DO-214AC) - standardized SMD footprint (5.28 mm × 4.50 mm × 2.29 mm) compatible with automated pick-and-place and reflow |
Pinout & Package
SMA (DO-214AC) package: surface-mount, bidirectional device with no polarity marking; symmetrical terminals enable mounting in either orientation on PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity surge) | Accepts reverse surge current during negative transients; forms one side of bidirectional clamping path |
| Anode | Transient current exit (positive polarity surge) | Acts as cathode-equivalent during positive surges due to bidirectional symmetry; no dedicated cathode band |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines (e.g., RS-485, CAN, sensor bridges) without polarity concerns |
| 400 W peak pulse power (10/1000 µs) | Supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) surge immunity in industrial I/O modules without external series impedance |

| MSL Level 1 (260 °C peak reflow) | Eliminates pre-bake requirement during standard lead-free assembly, reducing production cost and cycle time |
Applications
| Industrial Sensor Interface | Automotive LIN Bus Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VBR (60.8–67.2 V), larger SMB package (DO-214AA), 600 W PPPM, same bidirectional configuration | Better suited for higher-energy surges where PCB space allows larger footprint; not drop-in compatible due to different pad layout | Select SMBJ64CA when system-level surge testing requires >400 W margin or when thermal dissipation demands lower RθJA |
| 1.5KE68CA | Through-hole TO-204AE (DO-201AE) package, same VBR range, 1500 W PPPM, higher VC (118 V) | Used in legacy designs or high-power AC mains protection where manual assembly or wave soldering is preferred | Choose 1.5KE68CA only for through-hole prototyping or repair scenarios - not suitable for new SMT designs due to footprint and assembly constraints |
Compared with SMBJ64CA and 1.5KE68CA, the P4SMA62CA-M3/61 offers optimal balance of compact SMA footprint, verified AEC-Q101 qualification, and precise 62 V clamping for modern SMT-based industrial and automotive electronics - making it the preferred choice where board space, reliability certification, and repeatability are prioritized over raw power rating.

FAQ
What is the maximum clamping voltage of the P4SMA62CA-M3/61 under a 10/1000 µs surge?
The P4SMA62CA-M3/61 has a maximum clamping voltage (VC) of 85.0 V at 4.7 A peak pulse current (IPPM) under a 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 worst-case transient events. Engineers must verify that downstream ICs tolerate this clamped voltage with sufficient margin.
Is the P4SMA62CA-M3/61 suitable for automotive applications?
Yes - the P4SMA62CA-M3/61 is halogen-free and RoHS-compliant, and its HM3 variant (e.g., P4SMA62CAHM3_A/H) is AEC-Q101 qualified for automotive use. While the M3 suffix alone indicates commercial-grade compliance, the HM3 suffix adds validated reliability for under-hood and body electronics. For full automotive qualification, specify the HM3 ordering code, not M3.
Does the P4SMA62CA-M3/61 have polarity markings on the package?
No - the P4SMA62CA-M3/61 is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction allows installation in either orientation on the PCB. This eliminates orientation errors during automated placement and simplifies layout for differential or floating signal lines such as RS-485 or CAN bus traces.
What is the thermal resistance of the P4SMA62CA-M3/61 in standard mounting conditions?
The P4SMA62CA-M3/61 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, as specified in Vishay document 88367. This value assumes standard FR-4 PCB with no internal copper planes; actual thermal performance improves with additional copper area or thermal vias.
How does the P4SMA62CA-M3/61 differ from unidirectional P4SMA62A-M3/61?
The P4SMA62CA-M3/61 is bidirectional with symmetrical clamping in both polarities and no polarity marking, while the P4SMA62A-M3/61 is unidirectional, features a cathode band, and clamps only in reverse bias. Their VBR, VWM, and VC values differ slightly: P4SMA62CA-M3/61 has VBR = 58.9–65.1 V and VWM = 53.0 V, whereas P4SMA62A-M3/61 has VBR = 58.9–65.1 V but VWM = 53.0 V only in reverse - forward conduction occurs at ~0.7 V.
