It features a standoff voltage of 185 V, breakdown voltage range of 198–242 V at 1 mA, clamping voltage of 342 V at 1.8 A peak pulse current, and operates across –55°C to +150°C junction temperature. Used in industrial power supplies and automotive ECUs requiring IEC 61000-4-5 surge immunity.
For engineers reviewing the P6SMB220CA datasheet, P6SMB220CA pinout, P6SMB220CA application, or P6SMB220CA equivalent, this page delivers verified electrical specs, DO-214AA package details, clamping performance under 10/1000 µs transients, thermal resistance data, and real-world alternative part guidance for robust circuit protection design.
Technical Context
The P6SMB220CA implements a silicon avalanche diode structure with glass-passivated junction, enabling fast sub-nanosecond response (<1.0 ps) to ESD and surge events. Its bidirectional configuration supports symmetrical clamping in AC-coupled or floating systems without polarity dependency.
It meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive load-dump and inductive-switching immunity, and complies with JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - confirming suitability for high-reliability reflow assembly.

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 | Same DO-214AA package; 600 W PPPM; VBR = 237–263 V; VC = 358 V @ 1.7 A | Higher clamping voltage (+16 V) and wider VBR tolerance; slightly lower IPPM | Acceptable where margin allows higher clamped voltage; verify system withstand level ≥358 V |
| 1.5KE220CA | Through-hole DO-15; 1500 W PPPM; VBR = 237–263 V; VC = 358 V @ 4.2 A | Higher power rating but incompatible SMT footprint; not drop-in replaceable | Use only when board redesign permits axial-leaded placement and higher surge duty cycle |
Compared with SMBJ220CA and 1.5KE220CA, the P6SMB220CA offers tighter VBR tolerance (198–242 V vs. 237–263 V), lower clamping voltage (342 V), and SMT compatibility - making it optimal for space-constrained, high-density industrial and automotive PCBs requiring precise voltage limiting.

FAQ
What is the maximum clamping voltage of the P6SMB220CA under standard 10/1000 µs surge conditions?
The P6SMB220CA has a maximum clamping voltage (VC) of 342 V when subjected to its rated peak pulse current of 1.8 A with a 10/1000 µs waveform. This value is measured per JEDEC standards and ensures downstream components see no more than 342 V during transient events - critical for protecting 300 V-rated capacitors and 400 V MOSFETs in industrial power stages. The P6SMB220CA maintains this clamping performance across its full operating temperature range.
Does the P6SMB220CA support bidirectional transient suppression, and how is polarity identified?
Yes, the P6SMB220CA is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions - ideal for AC lines or floating references. Unlike unidirectional variants, it has no functional anode/cathode distinction; the molded cathode band is present for mechanical orientation only and does not indicate electrical polarity. This behavior is confirmed in the device's "Devices for Bipolar Applications" section and electrical test conditions specifying "electrical characteristics apply in both directions."
What is the thermal resistance profile of the P6SMB220CA, and why does it matter for layout?
The P6SMB220CA has a junction-to-ambient thermal resistance (RθJA) of 55 °C/W and junction-to-case (RθJC) of 10 °C/W. These values directly impact PCB copper pour sizing: to sustain repeated surges without exceeding 150°C junction temperature, designers must allocate ≥40 mm² of 2-oz copper connected to both terminals. The RθJA value assumes standard JEDEC test board conditions - actual performance improves with enhanced thermal land patterns, making thermal design a key factor in reliability validation for the P6SMB220CA.
How does the P6SMB220CA comply with automotive surge immunity standards like ISO 7637-2?
The P6SMB220CA is explicitly rated to meet ISO 7637-2 Pulse 1 (inductive load disconnect), Pulse 2a/2b (switching transients), and Pulse 3a/3b (capacitive coupling noise), as stated in its official datasheet. Its 600 W peak pulse power rating, sub-1.0 ps response time, and clamping behavior under 10/1000 µs waveforms align with the energy and voltage thresholds defined in those pulses - enabling direct use in automotive body control modules, infotainment power inputs, and sensor interface protection without additional external circuitry for the P6SMB220CA.
Is the P6SMB220CA RoHS and halogen-free compliant, and what certifications confirm this?
Yes, the P6SMB220CA is RoHS compliant and halogen-free per IEC 61249-2-21, as documented in the official Taiwan Semiconductor datasheet (Version Q2209). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin-plated to J-STD-002 solderability standards. These qualifications are verified through TSC's internal material declarations and third-party lab testing - ensuring full regulatory alignment for export to EU, China, and other regulated markets where the P6SMB220CA is deployed.
