Product details
Overview
P6SMB220AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection of sensitive electronics. It features a 220 V standoff voltage (VWM), 231 V minimum breakdown voltage (VBR), 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines in industrial power supplies and automotive ECUs.
For engineers reviewing the P6SMB220AHE3_B/H datasheet, P6SMB220AHE3_B/H pinout, P6SMB220AHE3_B/H application, or P6SMB220AHE3_B/H equivalent, key selection criteria include clamping voltage margin relative to protected device's absolute maximum rating, thermal derating above 25 °C ambient, unidirectional polarity marking (cathode band), and AEC-Q101 qualification status for automotive-grade reliability validation.
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), but triggers into low-impedance conduction when transient voltage exceeds its 231 V breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and fast response time (<1 ns), enabling suppression of ESD, lightning-induced surges, and inductive switching spikes before downstream components are damaged.
The device is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports 150 °C maximum junction temperature, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for automated SMT assembly without moisture sensitivity concerns. Its SMB package provides 5.0 mm × 5.0 mm copper pad thermal dissipation per terminal per JEDEC standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 185 V - maximum continuous reverse operating voltage before significant leakage; defines upper limit of normal circuit operation. |
| VBR (Breakdown Voltage) | 209–231 V at 1 mA test current - precise voltage threshold where diode transitions from blocking to clamping mode. |
| VC (Clamping Voltage) | 328 V at 1.8 A IPPM - maximum voltage seen by protected circuit during worst-case 10/1000 μs surge; critical for ensuring downstream IC survival. |
| PPPM (Peak Pulse Power) | 600 W - energy-handling capacity for standardized 10/1000 μs transient; determines survivability against IEC 61000-4-5 Level 4 surges. |
| RθJA | 100 °C/W - thermal resistance from junction to ambient; requires PCB copper area design (0.2" × 0.2") to maintain TJ ≤ 150 °C at full power. |

| Package | SMB (DO-214AA) - industry-standard surface-mount outline with cathode band marking; compatible with standard pick-and-place feeders. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads, UL 94 V-0 flammability rating, and polarity indicated by cathode band on unidirectional types.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias | Connected to ground or lower-potential node in unidirectional configuration; must be routed with low-inductance path for effective surge shunting. |
| Cathode | Current exit point in forward bias; marked with band | Connected to protected line (e.g., 24 V rail or sensor input); clamping action occurs between cathode and anode when voltage exceeds VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 surges up to 4 kV (line-to-earth) without degradation over repeated events. |
| Glass passivated junction | Ensures stable VBR tolerance (±5%), low leakage (<1 μA at 185 V), and long-term reliability under thermal cycling. |
| AEC-Q101 qualification (HE3_B suffix) | Validates performance across -40 °C to +125 °C operating range and confirms resistance to mechanical shock, temperature humidity bias, and HTRB stress. |
| MSL Level 1 (260 °C peak) | Permits single-reflow soldering without baking; eliminates moisture-related popcorning risk in high-volume SMT production. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients, reducing stress on downstream MOSFET gate oxides and logic inputs. |

FAQ
What is the clamping voltage of P6SMB220AHE3_B/H at its rated peak pulse current?
The P6SMB220AHE3_B/H 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 JEDEC test conditions and represents the highest voltage that will appear across the protected circuit during a worst-case surge event - a critical parameter for ensuring compatibility with the absolute maximum ratings of downstream ICs and MOSFETs. The P6SMB220AHE3_B/H maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is P6SMB220AHE3_B/H qualified for automotive applications?
Yes, P6SMB220AHE3_B/H is AEC-Q101 qualified, as confirmed by the "HE3_B" suffix in its ordering code. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature humidity bias (THB), mechanical shock, and accelerated life testing - validating its use in automotive body control modules, infotainment power rails, and sensor interfaces. The P6SMB220AHE3_B/H operates reliably from -40 °C to +125 °C junction temperature and meets MSL Level 1 for lead-free reflow, supporting automotive manufacturing requirements.
How does the SMB package of P6SMB220AHE3_B/H affect thermal performance?
The SMB (DO-214AA) package of P6SMB220AHE3_B/H 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. This thermal performance enables safe dissipation of its 600 W peak pulse power under short-duration surges, provided PCB layout follows Vishay's recommended pad dimensions. For continuous power handling, the P6SMB220AHE3_B/H is limited to 5.0 W at TA = 50 °C - meaning sustained overvoltage conditions require upstream current limiting to avoid thermal runaway.
What is the polarity configuration of P6SMB220AHE3_B/H and how is it identified?
P6SMB220AHE3_B/H is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage and blocks forward current like a standard rectifier. Polarity is identified by a visible cathode band on the SMB package body - the end with the band is the cathode and must be connected to the line being protected (e.g., 24 V rail), while the anode connects to ground or reference potential. This configuration ensures proper clamping action during positive-going transients without forward conduction during normal operation.
Can P6SMB220AHE3_B/H replace older P6SMB220A variants in existing designs?
Yes, P6SMB220AHE3_B/H is a direct replacement for legacy P6SMB220A parts in terms of electrical specifications, package outline, and pinout - with added benefits of RoHS compliance and AEC-Q101 qualification. The "HE3_B" suffix indicates halogen-free, RoHS-compliant construction and automotive qualification, while retaining identical VWM (185 V), VBR (209–231 V), and VC (328 V) values. No PCB layout changes are required, and the P6SMB220AHE3_B/H supports the same 7" tape-and-reel delivery format (H code) as prior versions.
