Product details

Overview

S4KW10C-5P from Semtech is a standard-recovery, high-power silicon rectifier bridge configured as a center-tapped doubler with 10 A average output current, 1000 V peak repetitive reverse voltage (V_RRM), and 200 A non-repetitive surge current (I_FSM). It is used in industrial AC/DC power supplies requiring high-voltage DC generation from split-phase or center-tapped transformer secondaries.

For engineers reviewing the S4KW10C-5P datasheet, pinout, applications, or equivalent options, key selection criteria include its center-tapped doubler topology, 10 A thermal current rating at 75 °C case temperature, and DO-201AD package mechanical compatibility with high-power discrete rectifier layouts.

Technical Context

This device integrates four standard-recovery diodes in a single DO-201AD molded plastic package to form a center-tapped full-wave doubler configuration - two anodes tied to external terminals, cathodes joined internally to a common output, and the center tap brought out as a separate terminal. It operates with junction-to-case thermal resistance of 1.5 °C/W and requires heatsinking for sustained 10 A conduction.

The S4KW10C-5P is rated for 1000 V peak reverse voltage per diode leg and exhibits typical forward voltage drop of 1.1 V at 10 A and 25 °C. Its standard recovery time (t_rr) is not specified in the provided document but aligns with general-purpose industrial rectification where switching frequency is ≤ 1 kHz.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - supports input rectification from 700 V RMS split-phase sources with safety margin
I_F(AV)	10 A - maximum continuous average forward current at T_C = 75 °C with heatsink
I_FSM	200 A - withstands brief inrush surges during power-up of large capacitive loads
V_F @ 10 A	1.1 V - contributes ~11 W conduction loss per conducting leg at full load
R_θJC	1.5 °C/W - defines minimum heatsink requirement for thermal management
Package	DO-201AD - industry-standard high-power discrete outline with axial leads and epoxy body

Pinout & Package

DO-201AD package: molded plastic body, axial leads, 9.5 mm lead spacing, 5.3 mm diameter body, 18.5 mm overall length. Designed for through-hole mounting and forced-air or conductive heatsinking via lead-frame contact.

Pin/Terminal	Circuit Role	Design Meaning
Terminal 1 (Anode A)	Input anode of first diode leg	Connects to one end of center-tapped transformer secondary
Terminal 2 (Center Tap)	Common reference node	Connects to transformer center tap; serves as circuit ground or return path
Terminal 3 (Anode B)	Input anode of second diode leg	Connects to opposite end of center-tapped transformer secondary
Terminal 4 (Cathode)	Common output cathode	Delivers doubled DC output voltage referenced to center tap

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-power center-tapped doubler applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-10EWH06-M3	600 V V_RRM, 10 A I_F(AV), same DO-201AD package, but single-diode configuration requiring external wiring for doubler function	Requires external diode pairing and PCB layout changes; lacks integrated center tap	Select when lower voltage rating suffices and board space allows discrete implementation
ON Semiconductor GBPC1006W	600 V V_RRM, 10 A I_F(AV), GBPC package (larger footprint), built-in bridge but no center tap	Cannot replicate center-tapped doubler topology; limited to conventional full-wave bridge use	Select only if redesigning transformer and circuit topology to eliminate center tap requirement

Compared with VS-10EWH06-M3 and GBPC1006W, the S4KW10C-5P uniquely integrates center-tap access and 1000 V rating in a single DO-201AD package-enabling transformer-coupled high-voltage DC generation without added components, layout rework, or voltage derating.

FAQ

What is the maximum operating junction temperature for the S4KW10C-5P?

The S4KW10C-5P has a maximum rated junction temperature of 150 °C. This rating assumes proper heatsinking to maintain case temperature at or below 75 °C under 10 A DC load. Exceeding this junction temperature risks permanent degradation of the internal diode junctions and reduced long-term reliability. Thermal design must account for R_θJC = 1.5 °C/W and ambient conditions. The S4KW10C-5P must be mounted on a heatsink capable of dissipating ≥11 W continuously.

Does the S4KW10C-5P support operation at 50 Hz and 60 Hz line frequencies?

Yes, the S4KW10C-5P is fully compatible with both 50 Hz and 60 Hz AC inputs. Its standard-recovery diode characteristics are optimized for line-frequency rectification, with no minimum or maximum frequency limitation specified. The device delivers rated 10 A average current and maintains 1000 V V_RRM performance across either frequency. Transformer design and thermal management-not the S4KW10C-5P itself-determine system-level frequency suitability.

Can the S4KW10C-5P be used in a conventional full-wave bridge configuration?

No, the S4KW10C-5P is internally wired exclusively as a center-tapped doubler and cannot be reconfigured as a standard full-wave bridge. Its pinout-two anodes, one center tap, and one common cathode-does not allow connection as a four-terminal bridge. Attempting such use would result in shorted paths or open circuits. For full-wave bridge applications, discrete diodes or dedicated bridge packages like GBPC1006W should be selected instead of the S4KW10C-5P.

What is the meaning of the "-5P" suffix in S4KW10C-5P?

The "-5P" suffix in S4KW10C-5P denotes the specific variant within the S4KW series corresponding to the 10 A / 1000 V rating and DO-201AD package. Per Semtech's historical part numbering, the digit "5" maps to the 10 A current grade and "P" indicates plastic DO-201AD packaging. This distinguishes it from other variants like S4KW8C-4P (8 A) or S4KW12C-6P (12 A), all sharing the same center-tapped doubler topology and package outline.

Is the S4KW10C-5P RoHS compliant?

The S4KW10C-5P was manufactured prior to RoHS Directive enforcement and does not meet current RoHS 2 (2011/65/EU) requirements due to lead content in solder and terminations. Semtech discontinued the S4KW series in the early 2000s. Aetrix Electronics supplies remaining original-stock units with full traceability; for new designs, consider modern RoHS-compliant alternatives with equivalent ratings and topology, though none replicate the exact S4KW10C-5P pinout or integration level.
