Product details
Overview
P6SMB220AHE3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 220 V standoff voltage (VWM), 231 V maximum breakdown voltage (VBR), 328 V clamping voltage (VC) at 1.8 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial power supplies.
For engineers reviewing the P6SMB220AHE3_B/I datasheet, P6SMB220AHE3_B/I pinout, P6SMB220AHE3_B/I application, or P6SMB220AHE3_B/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold (209–231 V), limiting transient energy to safe levels for downstream components. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while the SMB package provides mechanical robustness and thermal dissipation via soldered leads.
The device is rated for 600 W peak pulse power under standardized 10/1000 μs waveform conditions, with derating above 25 °C ambient per Fig. 2. It supports repetitive surge events at 0.01 % duty cycle and meets J-STD-020 MSL Level 1 moisture sensitivity with 260 °C lead-free reflow peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC line operating margin. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA test current - Confirmed avalanche onset range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 328 V at 1.8 A IPPM - Peak voltage seen by protected circuit during worst-case 10/1000 μs surge; determines required downstream voltage tolerance. |
| PPPM (Peak Pulse Power) | 600 W - Energy-handling capacity under standard 10/1000 μs waveform; enables protection against IEC 61000-4-5 Level 3 surges. |
| TJ max | 150 °C - Maximum allowable junction temperature; sets thermal design limits for PCB copper pad area and airflow. |
| ID (Reverse Leakage) | 1.0 μA at VWM - Ultra-low leakage preserves system efficiency and prevents false triggering in high-impedance circuits. |
| RθJA | 100 °C/W - Thermal resistance from junction to ambient; informs heatsinking requirements when operating near PD = 5.0 W limit. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional polarity with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ220A-E3/5B | Same VWM/VBR/VC specs but SMA package (smaller footprint, higher RθJA = 140 °C/W); non-AEC-Q101. | Limited to commercial-grade consumer electronics; unsuitable for automotive due to lack of qualification and reduced thermal margin. | Select when board space is critical and automotive qualification is not required; verify thermal performance at full 600 W pulse rate. |
| 1.5SMC220A | Same electrical specs but SMC (DO-214AB) package (larger, higher power handling); AEC-Q101 available only in HE3 suffix variants. | Better thermal performance (RθJA ≈ 60 °C/W) but requires 30% more PCB area; suited for high-reliability industrial power supplies. | Choose for designs needing enhanced surge endurance margin or where existing layout accommodates larger SMC footprint. |

FAQ
What is the polarity configuration of P6SMB220AHE3_B/I?
P6SMB220AHE3_B/I is a unidirectional Transient Voltage Suppressor. Its cathode is marked with a band on the SMB package body, and it conducts only in reverse-bias avalanche mode - making it suitable for DC line protection where polarity is fixed. This differs from bidirectional variants (e.g., P6SMB220CA) which suppress surges regardless of polarity.
Does P6SMB220AHE3_B/I meet automotive qualification standards?
Yes, P6SMB220AHE3_B/I is AEC-Q101 qualified, as confirmed by the "HE3" and "_B" suffixes in its ordering code. It has passed stress tests including temperature cycling, highly accelerated life testing (HALT), and surge endurance per AEC-Q101 Rev D, enabling use in automotive body electronics and powertrain-adjacent modules.
What is the maximum clamping voltage of P6SMB220AHE3_B/I under surge conditions?
The maximum clamping voltage (VC) of P6SMB220AHE3_B/I is 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 the datasheet and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6SMB220AHE3_B/I be used in bidirectional signal line protection?
No, P6SMB220AHE3_B/I is unidirectional and must not be used on AC or bidirectional signal lines without external polarity management. For such applications, select the bidirectional variant P6SMB220CA or P6SMB220CHE3_B/I, which provide symmetrical clamping in both directions and have no polarity marking.
What is the thermal resistance and how does it affect layout for P6SMB220AHE3_B/I?
P6SMB220AHE3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C during repetitive 600 W pulses, designers must ensure adequate copper area, avoid thermal isolation, and consider derating above 25 °C ambient using Figure 2 in the datasheet.
