Product details

Overview

1N5822/54 from Vishay General Semiconductor is a 40 V, 3.0 A Schottky barrier rectifier in DO-201AD package with 0.525 V typical forward voltage at 3.0 A, 80 A non-repetitive surge rating, and -65 °C to +125 °C operating junction temperature-used for polarity protection and freewheeling in DC-DC converters.

For engineers reviewing the 1N5822/54 datasheet, 1N5822/54 pinout, 1N5822/54 application, or 1N5822/54 equivalent, key selection criteria include its low VF at high IF(AV), fast recovery without reverse recovery charge, and DO-201AD leaded package compatibility with through-hole power supply layouts.

Technical Context

This Schottky rectifier uses a planar metal-semiconductor junction to achieve near-zero reverse recovery time and minimal switching losses. Its guardring structure enhances ruggedness against transient overvoltage events while maintaining stable conduction under repetitive surge conditions (80 A, 8.3 ms).

The device operates up to 125 °C junction temperature with R_θJL = 10 °C/W, enabling reliable thermal performance in compact PCB-mounted designs. Its 40 V V_RRM and 0.525 V V_F at 3.0 A support efficient low-voltage output rectification in buck-derived topologies.

FAQ

What is the maximum junction temperature rating for the 1N5822/54?

The 1N5822/54 has a maximum operating junction temperature of +125 °C and a storage temperature range of -65 °C to +125 °C. This rating allows use in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations, provided thermal design accounts for R_θJL = 10 °C/W and lead temperature limits.

Does the 1N5822/54 have a specified reverse recovery time?

No-the 1N5822/54 is a Schottky barrier rectifier and exhibits no measurable reverse recovery time (t_rr ≈ 0) due to majority-carrier conduction. This eliminates reverse recovery losses and associated EMI, distinguishing it from PN-junction rectifiers. The 1N5822/54 datasheet confirms this behavior via near-zero Q_rr and instantaneous reverse characteristics.

What does the "/54" suffix indicate in 1N5822/54?

The "/54" suffix in 1N5822/54 denotes the preferred packaging code: 13-inch diameter paper tape and reel, with a base quantity of 1400 units per reel. This format supports automated through-hole insertion equipment and is distinct from the "/73" (ammo pack) variant. The 1N5822/54 part number uniquely identifies this packaging configuration.

Is the 1N5822/54 RoHS compliant?

Yes-the 1N5822/54 is RoHS compliant per Directive 2011/65/EU and meets JESD 201 Class 1A whisker test requirements. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and the molding compound complies with UL 94 V-0 flammability standards. Compliance is verified in Vishay document 88526.

How does the guardring feature improve reliability of the 1N5822/54?

The guardring in the 1N5822/54 mitigates edge-related electric field crowding, preventing premature avalanche breakdown during voltage transients. This structural enhancement increases ruggedness against repetitive overvoltage events-such as load dump or inductive kickback-without degrading forward conduction. The 1N5822/54 maintains stable V_F and leakage performance across its full temperature and surge rating envelope.
