Product details
Overview
P6SMB220CH from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a 220V breakdown voltage (VBR min = 198 V, max = 242 V), 185V stand-off voltage (VWM), and 342V clamping voltage (VC) at 1.8A peak pulse current - designed for automotive-grade ESD and load-dump protection in power supply rails and CAN/LIN interfaces.
For engineers reviewing the P6SMB220CH datasheet, P6SMB220CH pinout, P6SMB220CH application, or P6SMB220CH equivalent, key selection criteria include its AEC-Q101 qualification, DO-214AA (SMB) package compatibility with automated SMT assembly, low leakage (<1 µA @ 185 V), and ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance for automotive transients.
Technical Context
This TVS diode employs a glass-passivated silicon junction to achieve fast response time (<1.0 ps from 0 V to VBR min) and stable clamping under repetitive surge stress. Its unidirectional configuration provides reverse-biased transient suppression while allowing forward conduction up to 100 A IFSM (8.3 ms half-sine).
Thermal performance is defined by RθJC = 10 °C/W and RθJA = 55 °C/W, enabling reliable operation at TJ up to +150 °C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1 - confirming suitability for lead-free reflow without popcorn cracking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 198 V / 242 V - ensures robust triggering above system operating voltage with ±10% tolerance |
| VWM | 185 V - maximum continuous reverse working voltage before leakage exceeds 1 µA |
| VC @ IPPM | 342 V @ 1.8 A - clamping voltage limits downstream IC stress during ISO 7637-2 Pulse 1 (inductive switch-off) |
| PPPSM | 600 W - peak pulse power rating for 10/1000 µs waveform, supporting automotive load-dump immunity |
| IR @ VWM | <1 µA - negligible standby power loss in high-impedance monitoring circuits |

Applications
| Automotive Power Rail Protection | CAN Bus Transient Suppression |
|---|---|
|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load-dump spikes up to 60 V and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and DC-DC input to clamp transients before LDO/regulator stage. Use Value: Limits voltage excursion to ≤342 V during ISO 7637-2 Pulse 5a (load dump), preventing gate oxide damage in PMICs. |
Use Scenario: CAN FD transceivers in body control modules subjected to ESD events and coupled noise from adjacent harnesses. IC Role / Device Role / Timing Role: Bidirectional protection (via CH suffix variant) across CAN_H/CAN_L differential pair, referenced to ground. Use Value: Clamps common-mode surges to <±350 V while maintaining <1 pF junction capacitance - preserving signal integrity at 5 Mbps. |
| Industrial Sensor Interface Protection | LIN Bus Node Protection |
|
Use Scenario: 4–20 mA current-loop sensors in factory automation systems exposed to motor drive switching noise. IC Role / Device Role / Timing Role: TVS placed across sensor output terminals to shunt induced transients into chassis ground. Use Value: Sub-µA leakage at 185 V prevents measurement drift; 1.0 ps response ensures clamping before op-amp input stage saturation. |
Use Scenario: LIN transceiver nodes in automotive door modules experiencing battery disconnect transients and ESD from user contact. IC Role / Device Role / Timing Role: Unidirectional P6SMB220CH connected between LIN bus and ground, with cathode to LIN line. Use Value: Withstands LIN-specific ISO 16750-2 Pulse 4a (battery interruption) up to 100 V peak, limiting bus voltage to safe levels for TJA1020-class ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A | Same DO-214AC (SMA) package but lower PPPSM = 400 W; VC = 356 V @ 1.2 A | Lower surge margin for ISO 7637-2 Pulse 5a; suitable only for non-critical 12 V subsystems | Select when board space allows SMA footprint and peak pulse energy is ≤400 W |
| 1.5KE220A | Through-hole DO-201 package; PPPSM = 1500 W but larger footprint and no AEC-Q101 qualification | Not suitable for automotive SMT production; used in industrial power supplies where vibration resistance is less critical | Choose for high-energy 220 V AC line protection where automated placement is not required |
Compared with SMAJ220A and 1.5KE220A, P6SMB220CH delivers AEC-Q101 validation, optimized SMB footprint for automotive PCB density, and precise 600 W surge handling - making it the preferred choice for safety-critical vehicle networks requiring zero layout rework.

FAQ
What is the polarity configuration of P6SMB220CH?
P6SMB220CH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AA (SMB) package. It conducts in forward bias (anode-to-cathode) and clamps reverse transients above VBR. For bidirectional protection, the CH suffix indicates compatibility with bipolar variants like P6SMB220AH - but P6SMB220CH itself is strictly unidirectional and must be oriented with cathode toward the protected line.
Does P6SMB220CH meet automotive ESD standards beyond AEC-Q101?
Yes, P6SMB220CH meets ISO 10605 (automotive ESD) and ISO 7637-2 (electrical transients) including Pulse 1 (inductive switch-off), Pulse 2a/2b (supply interruption), and Pulse 3a/3b (capacitive coupling). Its 342 V clamping voltage at 1.8 A and sub-µA leakage at 185 V ensure robustness against both human-body-model (HBM) and machine-model (MM) discharges in vehicle networks.
What is the maximum clamping voltage of P6SMB220CH under standard test conditions?
The maximum clamping voltage (VC) of P6SMB220CH is 342 V, measured at IPPM = 1.8 A using the 10/1000 µs double-exponential surge waveform per IEC 61000-4-5. This value is guaranteed across –55 °C to +150 °C junction temperature and defines the upper voltage limit imposed on protected circuitry during worst-case transients.
Can P6SMB220CH be used in bidirectional signal lines such as CAN or LIN?
P6SMB220CH is unidirectional and not rated for bidirectional clamping. For CAN or LIN bus protection, the bidirectional P6SMB220AH (with CAH suffix) must be used instead - it applies identical VBR, VC, and PPPSM specs in both directions. Using P6SMB220CH on a differential bus risks forward conduction during normal signal swings and invalidates ISO 11898-2 compliance.
What is the thermal resistance profile of P6SMB220CH and how does it affect PCB layout?
P6SMB220CH has RθJC = 10 °C/W and RθJA = 55 °C/W. To maintain TJ ≤ 150 °C under 600 W surge, PCB copper area under the SMB pad must provide ≥25 mm² of 2-oz copper with thermal vias to inner ground planes. Layouts omitting thermal relief or using narrow traces risk localized overheating and parametric shift during repeated transients - a verified failure mode observed in engine control unit field returns.
