The 3N256 is a 400V, 2A single-phase bridge rectifier diode from On Semiconductor, part of the 3N25x series originally designed by Fairchild Semiconductor. It is housed in a compact KBPM through-hole package, making it suitable for commercial and industrial applications requiring low-cost rectification.
Key electrical specifications include a maximum repetitive reverse voltage (VRRM) of 400V, an average rectified forward current (IF(AV)) of 2A at 50°C (derated above), and a non-repetitive peak forward surge current (IFSM) of 60A. The forward voltage drop is typically 1.1V at 3.14A per element, and reverse leakage current is 5µA at 25°C rising to 500µA at 125°C. The device also features a total capacitance of 25pF per leg and an I²t rating of 15 A²s for fusing considerations.
Thermal characteristics include a power dissipation of 4.7W and a junction-to-ambient thermal resistance of 18°C/W per leg when mounted on an 12×12mm PCB pad. The operating junction temperature range is -55°C to 150°C, with storage temperature similarly rated. The device is UL certified (UL #E111753) and claimed RoHS3 compliant, though compliance status is unverified.
The maximum repetitive reverse voltage (VRRM) is 400V.
The average rectified forward current (IF(AV)) is 2.0A at TA = 50°C, with derating at higher temperatures.
The forward voltage (VF) is typically 1.1V per element at 3.14A.
The 3N256 is supplied in a KBPM through-hole package (4-SIP).
The non-repetitive peak forward surge current (IFSM) is 60A for an 8.3ms single half-sine-wave.
The junction operating temperature range is -55°C to 150°C.
The 3N256 is listed as RoHS3 compliant, but this status is unverified and should be confirmed with a certificate.
