Product details

Overview

S3G-13-F from Diodes Incorporated is a 400 V peak repetitive reverse voltage, 3.0 A average rectified output current, glass passivated surface-mount silicon rectifier diode in SMB package. It delivers 1.15 V forward voltage at 3.0 A, supports 100 A non-repetitive surge current (8.3 ms), and operates from −65 °C to +150 °C. It is used in AC/DC input stage rectification for industrial power supplies.

For engineers reviewing the S3G-13-F datasheet, S3G-13-F pinout, S3G-13-F application, or S3G-13-F equivalent, key selection criteria include its 400 V V_RRM, 3.0 A I_O rating at T_T = +75 °C, 100 A I_FSM surge capability, thermal resistance of 10 °C/W (junction-to-terminal), and RoHS-compliant matte tin plating.

Technical Context

This device is a single-phase, half-wave silicon rectifier optimized for high-current, medium-voltage AC input rectification. Its glass passivated die construction ensures stable reverse leakage (<10 µA at 25 °C, <250 µA at 125 °C) and robust surge immunity under line-transient conditions.

The SMB package provides standardized surface-mount compatibility with 5.0 mm² copper pad thermal relief, enabling reliable power dissipation in compact board layouts. Its polarity is marked by a cathode band, and it exhibits 40 pF typical junction capacitance at 1.0 MHz and 4.0 V reverse bias.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - Withstands peak reverse voltage up to 400 V without breakdown in AC line applications.
I_O	3.0 A @ T_T = +75 °C - Continuous DC output current rating under standard thermal mounting condition.
V_FM	1.15 V @ I_F = 3.0 A - Low conduction loss enables efficient power conversion and reduced thermal stress.
I_FSM	100 A (8.3 ms half-sine) - Handles inrush and transient surges common in unregulated AC inputs.
R_θJT	10 °C/W - Junction-to-terminal thermal resistance measured with 5.0 mm² copper pad, critical for thermal design margin.
I_RM	10 µA @ 25 °C, 250 µA @ 125 °C - Confirmed reverse leakage limits ensure reliability in high-temp environments.
C_T	40 pF @ 1.0 MHz, 4.0 V - Low junction capacitance minimizes switching noise and EMI in rectifier front-ends.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SB340-TB	Same SMB package, 40 V V_RRM, 3.0 A I_O, Schottky architecture	Lower V_F (0.55 V), but limited to ≤40 V applications	Select only for low-voltage DC-DC input stages where 400 V rating is unnecessary.
ES3G-E3/57T	Same 400 V V_RRM, 3.0 A I_O, but SMC package (larger thermal mass)	Higher thermal capacity (R_θJT ≈ 7.5 °C/W), requires larger PCB pad	Prefer when higher continuous power dissipation or derating margin is required.

Compared with SB340-TB and ES3G-E3/57T, S3G-13-F offers optimal balance of 400 V capability, SMB footprint, and cost-effective glass-passivated construction for general-purpose AC/DC rectification-without Schottky leakage trade-offs or SMC layout overhead.

FAQ

What is the maximum allowable junction temperature for S3G-13-F?

The absolute maximum junction temperature is +150 °C, and the device is rated for continuous operation across −65 °C to +150 °C. Derating begins above +75 °C case temperature, per the forward current derating curve in DS16005 Rev. 18–2.

Is S3G-13-F suitable for full-bridge rectifier configurations?

Yes - S3G-13-F is a single diode rated for half-wave use but commonly deployed in full-bridge configurations (four units). Its 400 V V_RRM supports 200 VAC RMS bridge applications with adequate safety margin, and its 100 A I_FSM handles bridge inrush.

Does S3G-13-F require heatsinking in standard PCB layouts?

No external heatsink is required if mounted on a minimum 5.0 mm² copper pad (0.013 mm thick), per datasheet thermal test condition. R_θJT = 10 °C/W assumes this layout; smaller pads increase thermal resistance and require current derating.

How does the glass passivation benefit long-term reliability?

Glass passivation protects the silicon PN junction from moisture ingress, ionic contamination, and surface charge accumulation-reducing parameter drift and premature failure in humid or chemically aggressive industrial environments over 10+ year service life.
