POWEREX R6100128XXYZ 100 Volt 280 Amp DO-9 Stud Mount Diode:
$45.00

Powerex (PRX USA) R610-series general-purpose stud-mountsilicon rectifier diode (standard recovery), specifically the R6100128XXYZvariant.

PRX is the marking used by Powerex (a U.S. powersemiconductor maker, historically linked to Westinghouse/Mitsubishi Electriclines). The full marking “PRX USA R6100128XXYZ” plus the secondary codes (9949/ 10829) matches their discrete stud-diode family. The extra numbers aretypical date/lot codes (e.g., 9949 ≈ week 49 of 1999).

Numbering breakdown (Powerex R6xx convention)

R610 = series (stud-mount forward polarity—cathode to base/stud).

(R611 = same series, reverse polarity.)

01 = voltage class → 100 V VRRM.

28 = current rating code → ~280 A average (IF(AV); theseries covers roughly 200–300 A devices).

XXYZ = recovery/lead/package options (XX = standardrecovery; YZ = specific terminal/stud lead style).

Comparable catalog entries include R6100225XXYZ (200 V / 250A), R6100630XXYZ (600 V / 300 A), R6100830XXYZ (800 V / 300 A), etc., all inDO-205AB / DO-9 stud packages.

Key characteristics (typical for the R610 family)

Package: chassis/stud mount (DO-205AB / DO-9 style).

Technology: standard recovery (>500 ns).

Polarity: standard (forward).

Typical ratings for nearby parts in the family: hundreds ofamps average, surge currents in the multi-kA range, Vf around 1.4–1.5 V at highcurrent, Tj max ~190 °C.

Common uses: high-current rectifiers, battery chargers,power supplies, industrial DC systems.

These parts (especially the glass-seal versions in theR610/R611 line) were largely discontinued years ago; ceramic-seal equivalents(e.g., certain R600-series devices) were suggested as replacements at the time.

Exact electrical limits for the precise 0128 code are bestconfirmed from an original Powerex datasheet (search “Powerex R6100120” or thebroader R610 family datasheets, as the 012x variants share the same basedocument).

All of the diodes offered in this listing have the same datecode (9949) and lot code (10829). These diodes also are the glass sealedversion.
