Product details

Overview

S10KCHM6G from Taiwan Semiconductor is a 10A, 800V surface-mount glass-passivated silicon rectifier diode in DO-214AB (SMC) package, featuring low forward voltage drop (≤1.1 V at 10 A), high surge current capability (250 A), and junction temperature rating up to +150°C - deployed in AC/DC front-end stages of industrial SMPS and LED drivers.

For engineers reviewing the S10KCHM6G datasheet, S10KCHM6G pinout, S10KCHM6G application, or S10KCHM6G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (R_θJL = 10 °C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

This single-die standard recovery rectifier operates with a maximum junction temperature of +150°C and supports continuous forward current of 10 A at case temperature ≤75°C. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge immunity under 8.3 ms half-sine transients.

The DO-214AB (SMC) package delivers low thermal resistance (R_θJL = 10 °C/W) and meets UL 94V-0 flammability requirements. Cathode polarity is marked by a visible band, and matte tin-plated leads comply with J-STD-002 solderability and JESD 201 Class 2 whisker resistance standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	800 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in bridge or output rectification circuits
I_F	10 A - Continuous average forward current at T_C = 75°C; determines heatsink sizing for steady-state conduction loss
I_FSM	250 A - Non-repetitive peak surge current (8.3 ms); enables reliable operation during line-voltage transients or cold-start surges
V_F	≤1.1 V @ 10 A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design in high-current rectifiers
R_θJL	10 °C/W - Junction-to-lead thermal resistance; critical for estimating die temperature rise under PCB copper pad cooling
C_J	60 pF @ 4 V - Junction capacitance affects high-frequency switching noise and EMI filter design in SMPS

Pinout & Package

DO-214AB (SMC) surface-mount package: cathode-anode configuration with molded body, matte tin-plated leads, and cathode polarity indicated by a band on the cathode end.

Pin/Terminal	Circuit Role	Design Meaning
Anode (Lead 1)	Input terminal for forward conduction path	Connected to AC input or transformer secondary; must withstand full reverse voltage when reverse-biased
Cathode (Lead 2)	Output terminal for forward conduction path	Delivers rectified DC output; carries full load current and requires adequate copper pour for thermal dissipation

Equivalent & Alternatives

The following parts are listed as comparable options for similar rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH10R06DJF	600 V V_RRM, 10 A, TO-277 package, faster recovery (t_rr ≈ 65 ns)	Lower voltage rating; suited for 230 VAC-only systems with tighter layout constraints	Select when faster recovery and lower EMI are prioritized over 800 V margin
ON Semi MUR1080CT	800 V V_RRM, dual common-cathode configuration, TO-220AC package	Through-hole mounting; higher thermal mass but incompatible with SMT-only lines	Choose for legacy designs requiring through-hole assembly or dual-diode redundancy

Compared with STTH10R06DJF and MUR1080CT, the S10KCHM6G offers superior voltage margin and SMT scalability in a moisture-insensitive, halogen-free package - making it optimal for new industrial and lighting platforms targeting automated manufacturing and long-term supply continuity.

FAQ

What is the maximum junction temperature rating for S10KCHM6G?

The S10KCHM6G has a maximum junction temperature (T_J) rating of +150°C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet. This allows operation in high-ambient environments such as enclosed LED luminaires or industrial enclosures. Derating curves confirm usable current capacity down to 0 A at 150°C case temperature. Thermal design must account for R_θJL = 10 °C/W to ensure the S10KCHM6G stays within this limit under full load.

Does S10KCHM6G meet RoHS and halogen-free requirements?

Yes, the S10KCHM6G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the Taiwan Semiconductor product documentation. The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. These certifications are validated for the DO-214AB (SMC) package variant shipped under ordering code S10KCHM6G.

What is the marking code printed on the S10KCHM6G device body?

The S10KCHM6G is marked with "S10KC" on its body, consistent with Taiwan Semiconductor's standard coding for the 800 V variant in the S10GC–S10MC family. The "H" denotes halogen-free material, "M" indicates tape-and-reel packaging (3,000 pcs), and "6G" specifies date code and factory information per internal TSC marking conventions.

Is S10KCHM6G suitable for use in automotive applications?

The S10KCHM6G is not qualified to AEC-Q101 or automotive-grade reliability standards. While its -55°C to +150°C storage and operating temperature range overlaps with some automotive ambient conditions, Taiwan Semiconductor explicitly states these devices are "not designed for use in medical, life-saving, or life-sustaining applications" - and does not list automotive qualification in any revision of the S10GC–S10MC datasheet. For automotive use, consult TSC's AEC-Q101-certified rectifier portfolio separately.

What is the moisture sensitivity level (MSL) of S10KCHM6G?

The S10KCHM6G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it may be stored indefinitely at ambient conditions (≤30°C / 85% RH) without baking prior to reflow. This eliminates dry-pack requirements and simplifies SMT line logistics - a key advantage over MSL 3+ rectifiers that require strict floor-life tracking and pre-reflow baking.
