Product details
Overview
P6SMB62CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 53.0 V standoff voltage (VWM), 62.0 V minimum breakdown voltage (VBR), 85.0 V maximum clamping voltage at 7.1 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB62CA-E3/52 datasheet, P6SMB62CA-E3/52 pinout, P6SMB62CA-E3/52 application, or P6SMB62CA-E3/52 equivalent, key selection criteria include bidirectional clamping symmetry, low clamping ratio (VC/VBR ≈ 1.37), MSL Level 1 moisture sensitivity, and AEC-Q101 qualification eligibility via HE3/HM3 variants.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical electrical characteristics in forward and reverse directions per JESD22-A114 test conditions. Its glass-passivated junction ensures stable breakdown behavior under repetitive surge stress, while the low incremental surge resistance supports fast energy dissipation during transient events.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. Its 10/1000 μs waveform response enables robust protection against inductive switching spikes and ESD-induced surges in DC-fed subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 53.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 58.9–65.1 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events |
| VC (Clamping Voltage) | 85.0 V at 7.1 A IPPM - Peak voltage seen by protected circuit during 10/1000 μs surge; critical for IC survivability |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity under standardized surge waveform; validates single-event robustness |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance nodes |
| TJ max. | 150 °C - Enables operation in under-hood automotive and industrial environments without derating below full rating |
| Package | SMB (DO-214AA) - Surface-mount footprint compatible with automated assembly; meets UL 94 V-0 flammability |

Applications
| Automotive Sensor Interface | Industrial PLC Analog Input |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor front-ends (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between signal line and ground, absorbing transients without disrupting DC bias or signal swing. Use Value: Maintains signal fidelity during 100 V/50 ms load dump events while limiting clamped voltage to ≤85 V - within safe operating area of 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers against field-wiring surges and ground bounce. IC Role / Device Role / Timing Role: Line-to-ground TVS on each analog input channel, providing symmetrical overvoltage suppression independent of signal polarity. Use Value: Prevents latch-up or permanent damage to precision op-amps and ADCs during 1 kV ring wave transients per IEC 61000-4-5. |
| Telecom Line Card Protection | Consumer USB Port ESD Guard |
Use Scenario: Front-end surge protection for Ethernet PHYs, DSL line drivers, and PoE-powered devices exposed to lightning-induced surges on twisted-pair cables. IC Role / Device Role / Timing Role: Primary-level TVS on differential pairs, coordinated with secondary GDT or polymer-based protectors for staged energy diversion. Use Value: Clamps common-mode transients to <85 V within nanoseconds, preserving signal integrity and enabling interoperability with IEEE 802.3af/at compliance requirements. |
Use Scenario: Secondary ESD protection on USB 2.0 data lines (D+/D−) and VBUS in smartphones, tablets, and docking stations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp placed after connector but before USB transceiver IC, shunting >8 kV HBM ESD pulses. Use Value: Adds <1 pF junction capacitance (per diode) - negligible impact on 480 Mbps signal rise time - while meeting IEC 61000-4-2 Level 4 (15 kV air/8 kV contact). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64CA | Same SMB package, 64 V VBR min, 104 V VC at 5.8 A; lower PPPM (400 W) | Limited to lower-energy transients; not suitable for IEC 61000-4-5 Level 3 | Select when cost sensitivity outweighs peak surge requirement and layout space allows minor derating |
| SMCJ64CA | Higher-power SMC package (DO-214AB), 64 V VBR min, 103 V VC at 13.7 A; 1500 W PPPM | Requires larger PCB area; better for repeated surge duty cycles or higher ambient temperatures | Choose when system-level surge testing exceeds 600 W or thermal management is constrained |
Compared with SMAJ64CA, P6SMB62CA-E3/52 delivers 50% higher peak pulse power in the same footprint; versus SMCJ64CA, it trades 2.5× surge capacity for 40% smaller board area and lower assembly cost - optimal for space-constrained, single-event surge scenarios.

FAQ
What is the clamping voltage of P6SMB62CA-E3/52 at its rated peak pulse current?
The P6SMB62CA-E3/52 has a maximum clamping voltage (VC) of 85.0 V at 7.1 A peak pulse current (IPPM) under a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuits during surge events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings. The P6SMB62CA-E3/52 maintains this clamping performance across its full operating temperature range.
Is P6SMB62CA-E3/52 suitable for automotive applications?
P6SMB62CA-E3/52 is RoHS-compliant and qualified to commercial grade standards; however, the base P6SMB62CA-E3/52 variant is not AEC-Q101 qualified. For automotive use, Vishay offers the P6SMB62CAHE3_B variant (with HE3 suffix), which adds AEC-Q101 qualification, extended temperature validation, and enhanced lot traceability. Engineers must specify the HE3 or HM3 suffix explicitly when automotive qualification is required - the P6SMB62CA-E3/52 itself does not carry that certification.
How does the bidirectional design of P6SMB62CA-E3/52 affect its circuit placement?
The bidirectional design of P6SMB62CA-E3/52 means it has no polarity marking and functions identically regardless of orientation on the PCB. It can be placed directly across any two nodes requiring symmetrical overvoltage protection - such as between a signal line and ground, or across a differential pair. This eliminates orientation errors during automated placement and simplifies layout for AC-coupled or floating interfaces where voltage polarity reverses, unlike unidirectional TVS diodes that require strict cathode/anode alignment. The P6SMB62CA-E3/52 leverages this symmetry for robust protection in both directions.
What is the thermal resistance of P6SMB62CA-E3/52, and how does it impact power dissipation?
P6SMB62CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per JEDEC standards. This value determines steady-state temperature rise under DC power dissipation: at its rated 5.0 W power dissipation (PD), junction temperature rises ~500 °C above ambient - confirming PD is only relevant for continuous operation, not transient suppression. For surge events, thermal mass dominates, and RθJA is less critical than peak pulse ratings. The P6SMB62CA-E3/52 relies on short-duration energy absorption rather than sustained thermal handling.
Does P6SMB62CA-E3/52 meet moisture sensitivity level (MSL) requirements for lead-free reflow?
Yes, P6SMB62CA-E3/52 meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This allows direct placement into lead-free reflow ovens without baking or dry-pack requirements, reducing manufacturing complexity and cost. The device's matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and its molding compound complies with UL 94 V-0 flammability. These attributes make P6SMB62CA-E3/52 suitable for high-volume, automated SMT production environments where process robustness is essential.
