Taiwan Semiconductor Corporation S10KCHR7G

Overview

S10KCHR7G from Taiwan Semiconductor is a surface-mount silicon rectifier diode with 800 V repetitive peak reverse voltage (V_RRM), 10 A average forward current (I_F), and low 1.1 V forward voltage drop at 10 A - designed for high-efficiency AC/DC conversion in compact power supplies.

For engineers reviewing the S10KCHR7G datasheet, S10KCHR7G pinout, S10KCHR7G application, or S10KCHR7G equivalent, key selection criteria include its DO-214AB (SMC) package thermal resistance (R_θJL = 10 °C/W), 250 A surge capability (I_FSM), and J-STD-020 Level 1 moisture sensitivity rating for reliable automated assembly.

Technical Context

This single-die, glass-passivated standard recovery rectifier operates across -55 °C to +150 °C junction temperature range and delivers stable reverse leakage (<1 µA at 25 °C, <250 µA at 125 °C) under rated V_R. Its 60 pF junction capacitance at 4 V reverse bias supports moderate-frequency switching in offline SMPS front-end stages.

The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AB molded case, which carries UL 94V-0 flammability rating and weighs approximately 0.270 g.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the S10KCHR7G?

The S10KCHR7G has a V_RRM of 800 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version D2102). This rating allows safe operation with 230 VAC mains input including transient surges, and is distinct from lower-voltage variants like S10GCHR7G (400 V) or S10MCHR7G (1000 V).

Does the S10KCHR7G meet RoHS and halogen-free requirements?

Yes, the S10KCHR7G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor documentation. These certifications are verified for the DO-214AB (SMC) package variant shipped under ordering code S10KCHR7G.

What is the thermal resistance from junction to lead (R_θJL) for the S10KCHR7G?

The S10KCHR7G has a typical junction-to-lead thermal resistance (R_θJL) of 10 °C/W, measured under standard test conditions per the Thermal Performance table. This value enables effective heat transfer to the PCB copper via the anode and cathode leads in the DO-214AB package.

Is the S10KCHR7G suitable for automated pick-and-place assembly?

Yes, the S10KCHR7G is optimized for automated placement: it carries J-STD-020 Moisture Sensitivity Level 1, requires no pre-baking, and features matte tin-plated leads compliant with J-STD-002 solderability standards - all confirmed in the Mechanical Data section of the official datasheet.

What is the forward voltage (V_F) specification for the S10KCHR7G at rated current?

The S10KCHR7G has a maximum forward voltage of 1.1 V at 10 A forward current and 25 °C junction temperature, per the Electrical Specifications table. This value is measured using a 0.3 ms pulse width and represents worst-case conduction loss under nominal operating conditions.
