Product details

Overview

S15GCHM6G from Taiwan Semiconductor is a 15A, 400V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (≤1.1 V at 15 A), and 350 A peak surge capability - deployed in freewheeling paths and switching-mode power supplies for telecom and computing systems.

For engineers reviewing the S15GCHM6G datasheet, S15GCHM6G pinout, S15GCHM6G application, or S15GCHM6G equivalent, key selection criteria include repetitive peak reverse voltage (400 V), thermal resistance (R_θJL = 8 °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 up to 15 A at ambient conditions. Its glass-passivated chip junction ensures stable reverse leakage (<1 µA at 25 °C, <250 µA at 125 °C) and high reliability under repeated surge stress.

The device uses a DO-214AB (SMC) package with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance. Polarity is marked by a cathode band; weight is approximately 0.270 g.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC-link or clamp circuits
I_F	15 A - Continuous average forward current rating at specified thermal conditions
I_FSM	350 A - Peak non-repetitive surge current (8.3 ms half-sine); determines robustness against inrush/short-circuit transients
V_F	≤1.1 V @ 15 A, 25 °C - Forward voltage drop directly impacts conduction loss and thermal design margin
R_θJL	8 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper or metal-core substrate
C_J	93 pF @ 1 MHz, 4 V - Junction capacitance affects high-frequency switching noise and snubber sizing

Pinout & Package

DO-214AB (SMC) surface-mount package with two terminals: anode and cathode. Cathode identified by molded band on body. Leads are matte tin-plated, J-STD-002 solderable, and meet JESD 201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side (e.g., switch node or ground return) in freewheeling path
Cathode	Forward current exit / reverse blocking terminal	Marked with band; connects to higher-potential rail (e.g., output capacitor positive or DC bus)

Key Features

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1504DI	15 A, 400 V, TO-220AC package; V_F = 1.15 V typical; R_θJA = 40 °C/W	Through-hole mounting; higher thermal resistance requires heatsink for same power level	Preferred where legacy through-hole assembly or higher surge margin (I_FSM = 400 A) is required
ON Semi MUR1540	15 A, 400 V, DO-214AB; fast recovery (t_rr = 60 ns); V_F = 1.25 V max	Lower reverse recovery charge - better for high-frequency (>100 kHz) PFC stages	Chosen when reduced switching loss outweighs slightly higher conduction loss

Compared with STTH1504DI and MUR1540, the S15GCHM6G offers superior SMT manufacturability (MSL 1, tape-and-reel), lower thermal resistance to lead (8 °C/W), and tighter V_F spec (≤1.1 V), making it optimal for space-constrained, high-volume telecom and server power designs.

FAQ

What is the maximum junction temperature rating for S15GCHM6G?

The S15GCHM6G has a maximum junction temperature (T_J) rating of +150 °C, verified per absolute maximum ratings table in the official TSC datasheet. This rating applies under steady-state and transient thermal conditions, provided the device remains within its specified thermal resistance limits (R_θJL = 8 °C/W). Exceeding this temperature risks permanent degradation of the glass-passivated junction in the S15GCHM6G.

Is S15GCHM6G suitable for reflow soldering without moisture preconditioning?

Yes, the S15GCHM6G is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020) without baking or dry-pack requirements. This eliminates moisture-related popcorning risk and simplifies SMT line integration for the S15GCHM6G.

Does S15GCHM6G have a specified reverse recovery time (t_rr)?

No - the S15GCHM6G is a standard recovery rectifier, and its datasheet does not specify reverse recovery time (t_rr). It is characterized for V_F, I_R, and surge performance, but not optimized for high-frequency switching. For t_rr-critical applications, consider fast-recovery alternatives like MUR1540 instead of the S15GCHM6G.

What marking code appears on the S15GCHM6G device body?

The S15GCHM6G is marked with "S15GC" on the cathode end of the DO-214AB (SMC) package, per TSC's ordering code convention. The "G" denotes 400 V V_RRM; "HM6G" suffix indicates tape-and-reel packaging (3,000 pcs/reel) and green compound - consistent with the full part number S15GCHM6G.

Can S15GCHM6G replace S15JC or S15KC in the same footprint?

No - while all share the DO-214AB (SMC) package, the S15GCHM6G is rated for 400 V V_RRM, whereas S15JC (600 V) and S15KC (800 V) have higher blocking voltages and different internal die structures. Substitution requires verification of circuit voltage stress margins; using S15GCHM6G in place of S15JC may result in premature failure under 600 V reverse bias.
