Product details
Overview
P4SMA62CA-E3/61 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 62 V breakdown voltage (VBR min/max = 58.9 V / 65.1 V), 400 W peak pulse power (10/1000 µs), and clamps to ≤85.0 V at 4.7 A peak pulse current. It is used for ESD and surge protection of I/O lines in industrial sensor interfaces and telecom equipment.
For engineers reviewing the P4SMA62CA-E3/61 datasheet, P4SMA62CA-E3/61 pinout, P4SMA62CA-E3/61 application, or P4SMA62CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, SMA (DO-214AC) package compatibility, low leakage (<1 µA at 53.0 V), AEC-Q101 qualification status, and thermal resistance (RθJA = 120 °C/W).
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the low incremental surge resistance enables effective energy diversion during transient events.
The device is rated for 400 W peak pulse power under 10/1000 µs waveform (derated to 300 W above 91 V), with maximum clamping voltage of 85.0 V at 4.7 A. It supports operating junction temperatures from –65 °C to +150 °C and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - Ensures reliable triggering above normal operating voltage while maintaining margin against false clamping. |
| VWM | 53.0 V - Maximum continuous working voltage; defines safe DC/AC operating limit before leakage rises sharply. |
| IPPM | 4.7 A - Peak pulse current capability under 10/1000 µs waveform; determines transient energy absorption capacity. |
| VC @ IPPM | ≤85.0 V - Clamped voltage during worst-case surge; directly limits stress on downstream ICs like microcontrollers or transceivers. |
| PPPM | 400 W - Peak pulse power rating; defines transient energy handling (E = P × t) for standardized lightning/surge immunity tests. |
| ID @ VWM | <1 µA - Ultra-low reverse leakage at stand-off voltage; prevents signal distortion or battery drain in always-on circuits. |
| RθJA | 120 °C/W - Junction-to-ambient thermal resistance; informs PCB copper pad design (0.2" × 0.2") for thermal reliability. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. No polarity marking for bidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point (bidirectional) | Accepts surge current in either polarity; connects to protected line without directional biasing. |
| Cathode | Transient current exit point (bidirectional) | Completes low-impedance path to ground or reference rail during overvoltage events; symmetrical with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., RS-485, CAN, USB D+/D−) without polarity concerns. |
| 400 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 3 (1 kV line-to-line, 2 kV line-to-ground) surge immunity requirements with margin. |
| Low clamping ratio (VC/VBR ≈ 1.36) | Minimizes voltage overshoot during transients, reducing risk of latch-up or damage to 3.3 V/5 V logic interfaces. |
| AEC-Q101 qualified (HE3/HM3 variants) | Validated for automotive-grade reliability; P4SMA62CA-E3/61 is commercial-grade but shares same die and process as qualified versions. |
| MSL Level 1, 260 °C peak reflow | Supports standard SMT assembly without moisture sensitivity handling; eliminates bake-out requirement pre-reflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Higher VBR (60.8–67.2 V), same SMA package, 600 W PPPM, RθJA = 85 °C/W | Better suited for higher-energy surges; requires larger PCB copper area for thermal management due to lower RθJA. | Select when system-level surge testing exceeds 400 W or when tighter VBR tolerance (±5%) is required. |
| 1.5SMC68CA | Same VBR range (64.6–71.4 V), SMC (DO-214AB) package, 1500 W PPPM, RθJA = 40 °C/W | Larger footprint (7.11 × 6.22 mm vs. 4.5 × 3.99 mm); higher power handling demands more board space and layout revision. | Choose only if legacy designs already use SMC footprint or require >1 kW surge rating; not drop-in compatible with P4SMA62CA-E3/61. |
Compared with SMBJ64CA and 1.5SMC68CA, P4SMA62CA-E3/61 offers optimal balance of compact SMA packaging, 400 W surge capability, and commercial-grade cost-ideal for space-constrained consumer and industrial designs where 600–1500 W ratings are unnecessary.

FAQ
What is the breakdown voltage tolerance of P4SMA62CA-E3/61?
The P4SMA62CA-E3/61 has a specified breakdown voltage range of 58.9 V to 65.1 V at 1.0 mA test current, representing a ±5% tolerance around the nominal 62 V rating. This tight VBR window ensures predictable clamping onset across production lots and temperature ranges, critical for protecting 48 V nominal systems or 5 V logic rails with adequate safety margin. The value is measured per ANSI/IEEE C62.35 standards.
Is P4SMA62CA-E3/61 RoHS-compliant and halogen-free?
Yes, P4SMA62CA-E3/61 carries the "E3" suffix, indicating it is RoHS-compliant per EU Directive 2011/65/EU and meets Vishay's commercial-grade material specifications. It is not halogen-free; for halogen-free compliance, the "M3" variant (e.g., P4SMA62CA-M3/61) must be selected. Both E3 and M3 meet JESD 201 Class 2 whisker resistance requirements.
Does P4SMA62CA-E3/61 have AEC-Q101 qualification?
No, P4SMA62CA-E3/61 is a commercial-grade part and not AEC-Q101 qualified. However, Vishay offers automotive-grade equivalents under the HE3 (RoHS-compliant, AEC-Q101) and HM3 (halogen-free, AEC-Q101) suffixes-e.g., P4SMA62CAHE3_A/H-for automotive applications requiring qualification. The die and process are shared, but only HE3/HM3 variants undergo full AEC stress testing.
What is the maximum clamping voltage of P4SMA62CA-E3/61 under surge conditions?
The maximum clamping voltage (VC) of P4SMA62CA-E3/61 is 85.0 V at 4.7 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is guaranteed across temperature and represents the upper limit of voltage seen by protected circuitry during worst-case transient events, making it suitable for safeguarding 75 V-rated components or providing margin for 60 V systems.
Can P4SMA62CA-E3/61 be used in bidirectional signal lines like RS-485 or CAN?
Yes, P4SMA62CA-E3/61 is explicitly designed for bidirectional applications-the "CA" suffix denotes bidirectional configuration, and its symmetrical VBR, VC, and leakage characteristics apply equally in both polarities. It is commonly deployed across differential pairs in RS-485, CAN, and LVDS interfaces, where polarity-agnostic clamping prevents miswiring errors and simplifies layout.
