Product details

Overview

ES3DB R5G from Taiwan Semiconductor is a 3A, 200V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.86V forward voltage at 3A/25°C, and 100A surge current capability - deployed in high-frequency switching power supplies and LED lighting converters.

For engineers reviewing the ES3DB R5G datasheet, ES3DB R5G pinout, ES3DB R5G application, or ES3DB R5G equivalent, key selection criteria include V_RRM = 200V, I_F = 3A, t_rr ≤ 35ns, thermal resistance R_θJA = 84°C/W, and SMB package compatibility with automated SMT assembly.

Technical Context

This discrete silicon rectifier uses a glass-passivated PN junction optimized for high-speed switching in DC-DC conversion stages. Its 35ns reverse recovery time minimizes switching losses in 100–500kHz SMPS topologies, while the 0.86V forward drop at rated current supports thermal efficiency under continuous 3A conduction.

The device operates across –55°C to +150°C junction temperature range and delivers stable performance up to 200V repetitive peak reverse voltage. Its DO-214AA (SMB) package provides low-profile mounting, J-STD-020 Level 1 moisture sensitivity, and matte tin-plated leads compliant with J-STD-002 solderability standards.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum non-repetitive reverse blocking voltage before breakdown; defines safe operating margin in 170VAC input rectification.
I_F	3 A - Continuous average forward current at T_A = 25°C on standard PCB pad; derates linearly above 25°C ambient.
t_rr	35 ns - Measured at I_F = 0.5A, I_R = 1.0A, I_rr = 0.25A; enables efficient operation in high-frequency flyback and boost converters.
V_F	0.86 V @ 3A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle applications.
R_θJA	84 °C/W - Junction-to-ambient thermal resistance on 10mm × 10mm Cu pad; determines required heatsinking for 3A continuous operation.
I_FSM	100 A - Non-repetitive surge current rating (8.3ms half-sine); withstands inrush and transient overloads in AC-DC front ends.

Pinout & Package

DO-214AA (SMB) surface-mount package with cathode band marking; two-terminal unidirectional configuration. Matte tin-plated leads meet J-STD-002 solderability; polarity indicated by visible cathode band on molded body.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L06S	V_RRM = 600V, t_rr = 30ns, V_F = 0.95V @ 3A - higher voltage rating but 11% higher forward drop.	Suitable for universal-input PFC front ends where 600V blocking is mandatory; less optimal for 200V-class secondary-side use.	Select when V_RRM margin >300V is required; avoid if minimizing conduction loss is primary goal.
ON Semi MUR320	V_RRM = 200V, t_rr = 35ns, V_F = 0.92V @ 3A - identical V_RRM and t_rr, but 7% higher V_F and DO-201AD package.	Requires PCB pad redesign due to larger DO-201AD footprint; not drop-in compatible with SMB layout.	Choose only if existing design uses DO-201AD; otherwise ES3DB R5G offers better thermal performance in SMB.

Compared with STTH3L06S and MUR320, ES3DB R5G delivers lowest forward voltage in SMB package at 200V rating, enabling higher efficiency in space-constrained secondary-side rectification without sacrificing recovery speed or thermal robustness.

FAQ

What is the maximum junction temperature rating for ES3DB R5G?

The ES3DB R5G has a maximum junction temperature (T_JMAX) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in enclosed industrial power supplies and thermally constrained LED driver modules. Derating curves confirm usable current capacity down to 1.8A at 100°C ambient when mounted on a standard 10mm × 10mm copper pad. The ES3DB R5G maintains specified electrical parameters within this full temperature range.

Does ES3DB R5G support lead-free reflow soldering?

Yes, ES3DB R5G features matte tin-plated leads qualified to J-STD-002 for solderability and compatible with standard lead-free reflow profiles (peak temperature ≤ 260°C). Its DO-214AA (SMB) package meets IPC/JEDEC J-STD-020 Level 1 moisture sensitivity, eliminating pre-bake requirements. The ES3DB R5G is RoHS-compliant and halogen-free per IEC 61249-2-21.

What is the reverse recovery time specification for ES3DB R5G?

The ES3DB R5G reverse recovery time (t_rr) is specified as ≤35ns under test conditions of I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A. This value is confirmed in the Electrical Specifications table and applies across the full operating temperature range. The ES3DB R5G achieves this performance via optimized silicon doping and junction geometry, making it suitable for 200–500kHz switching topologies.

Is ES3DB R5G pin-compatible with other devices in the ES3x series?

Yes, all ES3AB–ES3JB variants share identical DO-214AA (SMB) package dimensions, pinout, and terminal configuration - anode and cathode positions are fixed across the family. The ES3DB R5G can be substituted with ES3CB or ES3FB on the same PCB layout, provided voltage and thermal requirements are verified. Marking code "ES3DB" identifies the 200V variant specifically.

What is the typical forward voltage of ES3DB R5G at 3A and 125°C?

The typical forward voltage of ES3DB R5G is 0.84V at I_F = 3.0A and T_J = 125°C, as listed in the Electrical Specifications table. This represents a 2.3% reduction from its 25°C value (0.86V), reflecting positive temperature coefficient behavior. The ES3DB R5G maintains stable conduction characteristics across its full –55°C to +150°C junction range.
