Product details
Overview
P6SMB220CAHE3_B/H 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), 252 V minimum breakdown voltage (VBR), and 328 V maximum clamping voltage (VC) at 1.8 A peak pulse current (IPPM), designed to protect signal lines and power rails in automotive and industrial electronics against ESD and lightning-induced transients.
For engineers reviewing the P6SMB220CAHE3_B/H datasheet, P6SMB220CAHE3_B/H pinout, P6SMB220CAHE3_B/H application, or P6SMB220CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 600 W peak pulse power rating (10/1000 μs), low thermal resistance (RθJL = 20 °C/W), and compatibility with automated SMT assembly on standard PCB pad layouts.
Technical Context
This device operates as a voltage-clamped transient protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It exhibits fast response time (<1 ns), low incremental surge resistance, and stable clamping performance across -65 °C to +150 °C junction temperature range.
Designed for repetitive surge suppression, it sustains 600 W peak pulse power under 10/1000 μs waveform at 0.01% duty cycle, with derating above 25 °C ambient per Fig. 2. Its glass-passivated junction ensures robust reliability and meets MSL level 1 per J-STD-020 at 260 °C peak reflow temperature.

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 VWM/VBR/VC ratings, identical SMB package, but not AEC-Q101 qualified; RθJL = 25 °C/W | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment | Select when AEC-Q101 is not required and cost sensitivity outweighs automotive qualification needs |
| 1.5KE220CA | Higher power (1500 W), axial-leaded DO-201 package, VWM = 220 V, VC = 355 V at 4.3 A | Requires through-hole assembly; larger footprint; higher clamping voltage reduces margin for sensitive ICs | Choose for legacy through-hole designs or where higher single-pulse energy absorption is prioritized over SMT compatibility |
Compared with SMBJ220CA and 1.5KE220CA, P6SMB220CAHE3_B/H uniquely combines AEC-Q101 qualification, SMB surface-mount form factor, and optimized thermal resistance-making it the preferred choice for space-constrained, high-reliability automotive modules requiring zero layout change from standard SMT processes.

FAQ
What is the clamping voltage of P6SMB220CAHE3_B/H at its rated peak pulse current?
The P6SMB220CAHE3_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 the test conditions specified in the Vishay datasheet (Document Number: 88370), and defines the upper voltage limit imposed on protected circuitry during surge events. The low clamping ratio (VC/VWM ≈ 1.49) confirms effective transient suppression capability for 220 V systems.
Is P6SMB220CAHE3_B/H suitable for automotive applications?
Yes, P6SMB220CAHE3_B/H is AEC-Q101 qualified, as indicated by the "HE3" and "_B" suffixes in its ordering code. It has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 Rev D. Its operating junction temperature range of -65 °C to +150 °C and MSL Level 1 rating make it appropriate for under-hood and body-control module deployments where P6SMB220CAHE3_B/H serves as primary transient protection.
How does the bidirectional configuration of P6SMB220CAHE3_B/H affect its circuit placement?
The bidirectional nature of P6SMB220CAHE3_B/H eliminates polarity marking-no cathode band is present-and allows placement across any two points requiring symmetrical overvoltage protection, such as differential signal pairs (e.g., RS-485, CAN), AC-coupled lines, or floating power domains. Unlike unidirectional TVS diodes, P6SMB220CAHE3_B/H conducts identically in both directions, simplifying layout and eliminating orientation errors during automated assembly.
What is the thermal resistance from junction to lead (RθJL) for P6SMB220CAHE3_B/H, and why does it matter?
P6SMB220CAHE3_B/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W. This parameter quantifies how efficiently heat generated during surge events transfers from the silicon die to the PCB copper pads via the leads. A lower RθJL enables higher repetitive surge capability and improved reliability in thermally constrained layouts-critical when P6SMB220CAHE3_B/H is deployed in densely packed automotive ECUs or industrial PLCs without heatsinking.
Can P6SMB220CAHE3_B/H be used in place of a unidirectional TVS diode?
No-P6SMB220CAHE3_B/H is strictly bidirectional and must not replace unidirectional TVS diodes in DC-biased circuits where forward conduction would cause short-circuit failure. For example, placing P6SMB220CAHE3_B/H across a 24 V supply rail without series impedance risks forward conduction during normal operation. It is only suitable where symmetrical voltage excursions occur, such as AC signal paths or differential buses; always verify polarity requirements before substituting P6SMB220CAHE3_B/H in existing designs.
