Product details
Overview
P6SMB220CA-M3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 220 V standoff voltage (VWM), 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 μs waveform). It protects signal lines and power rails in industrial sensor interfaces and automotive ECUs against ESD and inductive switching transients.
For engineers reviewing the P6SMB220CA-M3/5B datasheet, P6SMB220CA-M3/5B pinout, P6SMB220CA-M3/5B application, or P6SMB220CA-M3/5B equivalent, this page delivers verified electrical specs, bidirectional clamping behavior, thermal resistance (RθJA = 100 °C/W), halogen-free RoHS compliance (M3 suffix), and AEC-Q101 qualification status - all critical for automotive-grade surge protection design-in.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional CA construction, with breakdown voltage (VBR) specified at 209–231 V (min/max) under 1 mA test current. Its low incremental surge resistance ensures stable clamping during fast transients, and it meets J-STD-020 MSL Level 1 with peak reflow temperature of 260 °C.
The device uses glass-passivated junction technology for robustness and reliability, supports repetitive surge duty cycle up to 0.01 %, and exhibits a temperature coefficient of VBR of +0.108 %/°C - enabling predictable performance across -65 °C to +150 °C operating junction range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ220CA-T3 | Same VWM/VC, but rated for 600 W with 8.3 ms half-sine surge (not 10/1000 μs); higher IFSM = 100 A unidirectional only. | Optimized for AC line surge (IEC 61000-4-5) rather than fast ESD; lacks AEC-Q101 qualification in standard grade. | Select when prioritizing high single-pulse energy absorption over fast transient response or automotive qualification. |
| 1.5KE220CA | Through-hole DO-201 package; same 220 V VWM, but VC = 355 V at 3.4 A; larger RθJA (~50 °C/W on PCB). | Requires manual or wave soldering; unsuitable for high-density SMT layouts; lower thermal efficiency in confined spaces. | Choose only for legacy through-hole designs or where board space permits larger footprint and higher clamping voltage is acceptable. |
Compared with SMBJ220CA-T3 and 1.5KE220CA, P6SMB220CA-M3/5B offers superior SMT manufacturability, verified AEC-Q101 qualification, tighter VC (328 V vs. 355 V), and optimized 10/1000 μs waveform response - making it the preferred choice for new automotive and industrial surface-mount surge protection designs.

FAQ
What is the clamping voltage of P6SMB220CA-M3/5B at its rated peak pulse current?
The P6SMB220CA-M3/5B has a maximum clamping voltage (VC) of 328 V at 1.8 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during surge events. The P6SMB220CA-M3/5B maintains this clamping performance across its full operating temperature range (-65 °C to +150 °C) with minimal drift due to its +0.108 %/°C VBR coefficient.
Is P6SMB220CA-M3/5B qualified for automotive applications?
Yes, P6SMB220CA-M3/5B is AEC-Q101 qualified when ordered with the "_B" revision suffix (as indicated in Note 1, page 3 of Vishay document 88370). The "-M3/5B" ordering code includes the halogen-free, RoHS-compliant M3 material set and the 13-inch tape-and-reel packaging format (5B), and the "_B" denotes AEC-Q101 qualification for automotive use. This makes P6SMB220CA-M3/5B suitable for engine control units, body electronics, and ADAS sensor modules.
How does the bidirectional design of P6SMB220CA-M3/5B affect its PCB layout?
The bidirectional CA configuration of P6SMB220CA-M3/5B eliminates polarity constraints: no cathode band marking is present, and both terminals function identically as transient return paths. This allows placement across AC-coupled lines, differential pairs, or floating references without orientation checks. Layout best practices still require symmetric, low-inductance traces to ground plane and minimum pad dimensions (0.2" × 0.2") per Vishay's thermal recommendations - critical for sustaining P6SMB220CA-M3/5B's 600 W rating.
What is the thermal resistance of P6SMB220CA-M3/5B, and how does it impact power derating?
P6SMB220CA-M3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads per Figure 2 in Vishay document 88370. This means each watt of steady-state dissipation raises junction temperature by 100 °C above ambient. Since P6SMB220CA-M3/5B is rated for 5.0 W continuous power (PD) at TA = 50 °C, its usable power must be linearly derated above that point - e.g., to ~3.5 W at 70 °C ambient - to stay within the +150 °C TJmax limit.
Does P6SMB220CA-M3/5B meet industry surge immunity standards such as IEC 61000-4-5?
P6SMB220CA-M3/5B is designed to support compliance with IEC 61000-4-5 Level 4 (4 kV line-to-earth, 2 kV line-to-line) when implemented with proper PCB layout: short traces, low-inductance grounding, and adequate copper pour. Its 600 W peak pulse power (10/1000 μs) and 328 V clamping voltage directly align with the energy and voltage limits of that standard. However, system-level validation is required - the P6SMB220CA-M3/5B itself is not certified to IEC 61000-4-5, but serves as a key enabling component in compliant designs.
