Product details
Overview
P6SMB220A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), used to protect power rails and signal lines in industrial power supplies and automotive ECUs against ESD and lightning-induced transients.
For engineers reviewing the P6SMB220A-E3/5B datasheet, P6SMB220A-E3/5B pinout, P6SMB220A-E3/5B application, or P6SMB220A-E3/5B equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJA = 100 °C/W), unidirectional polarity marking, RoHS-compliant matte tin plating, and 600 W peak pulse power capability with 10/1000 μs waveform.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at 185 V), then rapidly avalanches below 231 V to divert surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Designed for automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads per terminal, it meets J-STD-020 MSL Level 1 (peak reflow ≤260 °C) and supports repetitive transient suppression at 0.01% duty cycle, with junction temperature limited to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse voltage before significant leakage; sets upper limit of protected line operating range. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA - Confirmed avalanche onset range; ensures reliable triggering above system nominal voltage. |
| VC (Clamping Voltage) | 328 V at IPPM = 1.8 A - Peak voltage seen by protected device during 10/1000 μs surge; determines required voltage headroom. |
| PPPM (Peak Pulse Power) | 600 W - Sustained energy absorption capability for standardized 10/1000 μs waveform; defines transient robustness. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Negligible standby current; avoids loading sensitive reference or bias networks. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance; requires adequate PCB copper area for sustained 5.0 W dissipation. |
| Polarity | Unidirectional - Cathode marked by band; blocks forward conduction, clamps only reverse overvoltage events. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile plastic case meeting UL 94 V-0 flammability rating; terminals are matte tin plated, solderable per J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential rail; completes clamping path during reverse transient. |
| Cathode | High-side connection point | Marked by band; connected to protected line; conducts avalanche current into anode when VLINE exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection against IEC 61000-4-5 Level 4 surges (4 kV line-earth) without derating on standard PCB layouts. |
| Glass passivated junction | Ensures stable VBR over lifetime and temperature, with minimal drift (<0.108 %/°C) and high reliability in harsh environments. |
| MSL Level 1 compliance | Supports lead-free reflow up to 260 °C without preconditioning; eliminates moisture sensitivity handling overhead. |
| RoHS-compliant, matte tin plating | Guarantees solder joint integrity and long-term corrosion resistance in industrial and automotive applications. |
| AEC-Q101 qualification option (_B suffix) | Validated for automotive under-hood use; P6SMB220A-E3/5B itself is commercial grade but shares identical die and package design. |
Applications
| Industrial Power Supply Protection | Automotive Body Control Module (BCM) |
|---|---|

Use Scenario: Safeguards LIN bus transceiver power pins in BCM against battery disconnection spikes and alternator load dump. IC Role / Device Role / Timing Role: Unidirectional clamp referenced to chassis ground, absorbing negative-going transients on VCC line while blocking forward conduction. Use Value: Withstands 600 W pulses without degradation, preserving signal integrity and preventing latch-up in LIN PHY ICs. |
| Telecom AC/DC Adapter Input Stage | Motor Drive Gate Driver Supply Rail |
|
Use Scenario: Shields primary-side controller IC in 48 V telecom adapter from surges induced by nearby relay switching or lightning coupling. IC Role / Device Role / Timing Role: Standoff-rated TVS on bulk capacitor input, triggered only during overvoltage events exceeding 185 V. Use Value: 1.0 μA leakage at 185 V avoids unnecessary quiescent current draw, critical for Energy Star compliance. |
Use Scenario: Clamps positive voltage spikes on isolated gate driver supply (e.g., 15 V rail) caused by Miller capacitance coupling during IGBT turn-off. IC Role / Device Role / Timing Role: Fast-response shunt element across gate driver VDD and GND, activated within nanoseconds of overvoltage detection. Use Value: 30.6 ns typical response time prevents gate oxide overstress in SiC MOSFET drivers operating at >100 kHz switching frequency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A | Same VWM (185 V), VC = 328 V, but lower PPPM = 400 W; SMA package (DO-214AC), RθJA = 130 °C/W. | Lower power handling and higher thermal resistance limit use to lower-energy transients or better-cooled layouts. | Select when footprint constraints favor smaller SMA or when surge energy is consistently <400 W. |
| 1.5SMC220A | Same electrical specs (VWM = 185 V, VC = 328 V), but larger SMC (DO-214AB) package; RθJA = 75 °C/W, PPPM = 1500 W. | Higher thermal mass supports repeated surges and higher ambient temperatures; requires larger PCB area. | Choose for high-reliability industrial systems where 1500 W margin and lower junction temperature rise are critical. |
Compared with SMAJ220A, P6SMB220A-E3/5B delivers 50% higher surge power headroom and superior thermal performance; versus 1.5SMC220A, it trades 2.5× PCB area for tighter layout integration while retaining full 600 W capability.

FAQ
What is the clamping voltage of P6SMB220A-E3/5B at its rated peak pulse current?
The P6SMB220A-E3/5B has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value defines the highest voltage imposed on protected circuitry during a surge event and must be verified against downstream components' absolute maximum ratings. The P6SMB220A-E3/5B maintains this clamping performance across its specified operating temperature range.
Is P6SMB220A-E3/5B suitable for automotive applications?
P6SMB220A-E3/5B is RoHS-compliant commercial-grade; however, the P6SMB220A-HE3_B variant (same die and SMB package, with _B suffix) is AEC-Q101 qualified for automotive under-hood use. Engineers selecting P6SMB220A-E3/5B for automotive should confirm system-level qualification requirements-while the P6SMB220A-E3/5B shares identical electrical and thermal characteristics, only the HE3_B version carries formal automotive stress test validation.
What does the "E3/5B" suffix indicate in P6SMB220A-E3/5B?
The "E3" denotes RoHS-compliant, commercial-grade construction with matte tin-plated leads; "5B" specifies packaging in 13-inch diameter plastic tape and reel containing 3200 units. This differs from "E3/52", which uses 7-inch reels of 750 units. The P6SMB220A-E3/5B is optimized for high-volume SMT assembly lines requiring extended reel length and reduced changeover frequency.
How does the thermal resistance of P6SMB220A-E3/5B affect PCB layout?
P6SMB220A-E3/5B 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 TJ ≤ 150 °C at full 5.0 W steady-state dissipation, designers must allocate ≥25 mm² of 2-oz copper per pad and avoid thermal isolation. The P6SMB220A-E3/5B's SMB footprint enables compact routing while demanding deliberate copper area planning.
Can P6SMB220A-E3/5B be used in bidirectional configurations?
No-P6SMB220A-E3/5B is unidirectional, with cathode identified by a band. For bidirectional operation, select the P6SMB220CA variant (e.g., P6SMB220CA-E3/5B), which provides symmetrical clamping in both polarities. Using P6SMB220A-E3/5B in reverse-biased signal paths risks forward conduction and failure; its datasheet-specified parameters apply only for reverse-transient suppression.
