Product details
Overview
P6SMB220CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 220 V standoff voltage (VWM), 242–264 V breakdown voltage (VBR) at 1 mA test current, 328 V maximum clamping voltage at 1.8 A peak pulse current, and 600 W peak pulse power capability with a 10/1000 μs waveform - deployed in industrial sensor interfaces and automotive control modules.
For engineers reviewing the P6SMB220CA-E3/52 datasheet, P6SMB220CA-E3/52 pinout, P6SMB220CA-E3/52 application, or P6SMB220CA-E3/52 equivalent, this device serves as a robust, RoHS-compliant, AEC-Q101-qualified (via HE3 variant) transient protection solution for bidirectional DC lines where low-profile SMB packaging and fast sub-nanosecond response are critical.
Technical Context
The P6SMB220CA-E3/52 operates as a symmetrical avalanche diode, delivering identical clamping behavior in both forward and reverse directions due to its bidirectional CA construction. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 μA at 185 V), while the 100 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design per the 0.2" × 0.2" (5.0 mm × 5.0 mm) mounting recommendation.
It meets J-STD-020 MSL Level 1 moisture sensitivity and supports automated SMT placement. The device is rated for repetitive 0.01% duty cycle pulses and derates linearly above 25 °C ambient, maintaining reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before significant leakage; defines safe operating window for protected line. |
| VBR (Breakdown Voltage) | 242–264 V at IT = 1 mA - Confirmed avalanche initiation range; ensures predictable clamping onset under surge conditions. |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A (10/1000 μs) - Peak voltage seen by downstream circuit during worst-case transient; determines required IC withstand margin. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capacity for standardized lightning/surge waveforms; enables IEC 61000-4-5 Level 3 compliance. |
| ID (Reverse Leakage) | <1.0 μA at VWM - Minimal standby power loss and signal integrity impact on high-impedance lines. |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline (4.57 mm × 3.94 mm × 2.20 mm); compatible with standard 7" tape-and-reel (E3/52). |
| TJ max | 150 °C - Maximum junction temperature; sets thermal design limit for sustained power dissipation and surge repetition rate. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional - no polarity marking; symmetrical terminal configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Transient conduction path | Both terminals function identically; conducts in either direction once VBR is exceeded - eliminates orientation concerns during placement. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating DC lines without polarity constraints. |
| 600 W peak pulse power (10/1000 μs) | Withstands common surge events including IEC 61000-4-5 combination wave (2 Ω source) up to ±1 kV. |
| Glass passivated junction | Ensures long-term stability of VBR and low parametric drift across temperature and lifetime. |
| MSL Level 1 rating | Allows unlimited floor life and reflow compatibility with standard lead-free solder profiles (peak 260 °C). |
| RoHS-compliant, matte tin-plated leads | Meets J-STD-002/JESD22-B102 solderability standards; supports high-yield automated assembly. |
Applications
| Industrial Sensor Interface Protection | Automotive Body Control Module (BCM) |
|---|---|
Use Scenario: Protecting 24 V CAN or LIN bus signal lines from load dump and inductive switching transients in factory automation systems. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt surge energy before reaching transceiver IC. Use Value: Limits line voltage to ≤328 V during 1.8 A transients, preserving signal integrity and preventing latch-up in ISO 11898-compliant PHYs. |

| Telecom Line Card Surge Protection | Consumer Appliance Motor Drive Feedback |
Use Scenario: Shielding RS-485 transceivers on telecom base station line cards from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Secondary-level TVS on differential pair, positioned after gas discharge tube (GDT) primary protection. Use Value: Clamps residual transients to <330 V within nanoseconds, meeting GR-1089-CORE Level 3 requirements. |
Use Scenario: Protecting hall-effect sensor outputs in washing machine motor control boards from commutation spikes. IC Role / Device Role / Timing Role: Localized TVS at sensor output pin to suppress <100 ns ringing and ESD events. Use Value: Sub-1 nS response time prevents false triggering of MCU ADC inputs, maintaining accurate rotor position detection. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA | Same SMB package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VC tolerance (±5 % vs. ±10 % typical for P6SMB). | Preferred in high-reliability telecom where clamping consistency across batch is critical. | Select SMBJ220CA if tighter VC distribution and MIL-STD-750-tested reliability are required; P6SMB220CA-E3/52 offers broader commercial cost advantage. |
| 1.5SMC220CA | Larger SMC (DO-214AB) package (7.11 mm × 6.22 mm), same electrical specs, higher thermal mass (RθJA = 60 °C/W). | Better suited for high-duty-cycle or elevated ambient environments (>85 °C) where SMB thermal limits are marginal. | Choose 1.5SMC220CA when board space allows and thermal derating headroom is needed; P6SMB220CA-E3/52 prioritizes compactness and SMT efficiency. |
Compared with SMBJ220CA and 1.5SMC220CA, P6SMB220CA-E3/52 delivers identical transient suppression performance in the smallest footprint, optimized for cost-sensitive, high-volume consumer and industrial designs where SMB-level thermal management suffices.

FAQ
What is the maximum clamping voltage of the P6SMB220CA-E3/52 under a 10/1000 μs surge?
The P6SMB220CA-E3/52 has a maximum clamping voltage (VC) of 328 V when subjected to a 1.8 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuitry during transient events. Engineers must ensure downstream components tolerate ≥328 V peak stress.
Is the P6SMB220CA-E3/52 suitable for automotive applications?
The P6SMB220CA-E3/52 itself is RoHS-compliant and commercial-grade; however, Vishay offers AEC-Q101-qualified variants under ordering codes like P6SMB220CAHE3_B/H. For automotive use, specify the HE3 or HM3 suffix - the P6SMB220CA-E3/52 is not qualified but shares identical electrical specs and can serve in non-safety-critical prototype or aftermarket contexts pending validation.
Does the P6SMB220CA-E3/52 have polarity markings on the package?
No, the P6SMB220CA-E3/52 is a bidirectional TVS diode and carries no cathode band or polarity marking on the SMB (DO-214AA) case. Its symmetrical construction means both terminals behave identically - installation orientation is irrelevant, simplifying automated placement and reducing assembly errors in high-density layouts.
What is the thermal resistance and recommended PCB layout for the P6SMB220CA-E3/52?
The P6SMB220CA-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain reliability under repeated surges, adhere strictly to this pad layout - undersized copper reduces power handling and accelerates thermal degradation. No internal heatsink is required for single-pulse events.
How does the P6SMB220CA-E3/52 compare to unidirectional P6SMB220A variants?
The P6SMB220CA-E3/52 provides symmetrical clamping for AC or floating DC lines, whereas the unidirectional P6SMB220A clamps only in reverse bias and conducts forward current like a rectifier. Use P6SMB220CA-E3/52 when protecting bidirectional signals (e.g., RS-485, CAN) or circuits without defined ground reference; choose P6SMB220A only for dedicated DC rail protection with clear polarity.
