6. Frequently Asked Questions
▶>
The W06 is typically rated ~1.5 A average current and 600 V peak reverse (600 V blocking). Its forward voltage drop is ~1.1 V at 1.5 A, and reverse leakage about 10 µA at 600 V. It can survive brief surges (~40–50 A).
>
The W06 is a 600 V rated bridge, whereas the W08 is similar but rated for 800 V (and often 1.5 A as well). Internally they use the same package style; the number difference reflects reverse voltage.
>
W06 uses a round plastic (molded epoxy) case with four leads (WOB/RB-15 style). Two leads (opposite pins) are AC inputs and two are DC outputs (+ and –), as marked on the case. It mounts flat on a PCB.
>
Designers must allow for its ~1.1 V forward drop per diode (so ~2.2 V drop total) and heat generation. A heatsink or good PCB copper can help. Also include a smoothing capacitor on the DC output to reduce ripple. Ensure the 1.5 A continuous current rating is not exceeded. Check ambient temperature: it’s typically specified to 125 °C junction (–55 to +150 °C range).

Yes. Common equivalents include KBP06, MB6S, KBPC06, etc., which are all ~1.5 A, 600 V bridge rectifiers. Some suppliers list the W06 (MultiComp) obsolete, so these alternatives (or higher-current “2W06” series) are used. Also W06G (glass-passivated variant) is similar.
>
Many distributors (Digi-Key, Mouser, RS, etc.) and online retailers carry equivalents. Prices are low, but stock levels vary. Some show it as an older stock item; alternatives (KBP06, 2W06 for 2 A) may have better availability. Always verify specs when substituting.
