Product details

Overview

ES3D from Taiwan Semiconductor is a 3 A, 200 V super fast recovery surface-mount rectifier diode in DO-214AB (SMC) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 3 A and 25°C, and 10 µA reverse leakage at rated VR and 25°C - used for high-frequency freewheeling and SMPS output rectification in telecom power supplies.

For engineers reviewing the ES3D datasheet, ES3D pinout, ES3D application, or ES3D equivalent, key selection criteria include peak repetitive reverse voltage (200 V), ultra-fast trr (≤35 ns), thermal resistance (R_θJL = 12 °C/W), junction temperature range (–55 to +150°C), and DO-214AB mechanical compatibility with automated SMT assembly.

Technical Context

The ES3D is a single-die, silicon planar junction rectifier with glass-passivated chip construction, optimized for high-efficiency switching-mode power conversion. Its 35 ns reverse recovery time enables operation at frequencies up to several hundred kHz without excessive switching loss.

Thermal performance is defined by R_θJL = 12 °C/W and R_θJA = 47 °C/W, supporting continuous 3 A conduction at ambient temperatures up to 85°C with standard PCB copper area. The device uses matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Key Specifications

V_RRM	200 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths
I_F	3 A - average forward current rating; supports continuous DC output rectification in 30–60 W SMPS designs
t_rr	35 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables low-loss switching in high-frequency converters
V_F	0.95 V max at I_F = 3 A, T_J = 25°C - directly determines conduction loss and thermal load in output stage
C_J	45 pF typical at 1 MHz, V_R = 4.0 V - impacts EMI generation and snubber design in high-dV/dt applications

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-3EYH02-M3/45	V_RRM = 200 V, t_rr = 30 ns, V_F = 0.92 V @ 3 A - slightly faster but same package and rating	Same DO-214AB footprint; lower V_F improves light-load efficiency in battery-backed systems	Preferred where <5 ns t_rr reduction justifies cost premium and tighter V_F tolerance is required
ON Semiconductor MUR320	V_RRM = 200 V, t_rr = 35 ns, V_F = 0.97 V @ 3 A - identical speed, marginally higher V_F, same package	Compatible pinout and thermal profile; qualified to AEC-Q101 for automotive auxiliary supplies	Selected when automotive qualification or extended manufacturer warranty coverage is mandatory

Compared with VS-3EYH02-M3/45 and MUR320, the ES3D offers identical 200 V/3 A/35 ns performance with lower unit cost and Taiwan Semiconductor's industrial-grade reliability certification - making it optimal for cost-sensitive telecom and industrial power supplies where AEC-Q101 is not required.

FAQ

What is the maximum junction temperature rating for ES3D?

The ES3D has a maximum junction temperature (T_J) rating of +150°C and a minimum of –55°C. This wide operating range allows reliable use in enclosed industrial enclosures and high-ambient telecom equipment. Derating curves in the ES3D datasheet confirm 3 A average forward current is sustainable up to 85°C ambient with standard 1-inch² copper pad.

Does ES3D have a specified reverse recovery charge (Q_rr) value?

The ES3D datasheet does not publish a direct Q_rr value, but its 35 ns reverse recovery time (t_rr) is measured under standardized conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A). Q_rr can be estimated using t_rr and diode capacitance (C_J = 45 pF); typical Q_rr for ES3D falls between 12–15 nC in practical SMPS circuits.

Is ES3D compatible with lead-free reflow soldering profiles?

Yes, ES3D is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the DO-214AB package is rated for peak reflow temperatures up to 260°C per JEDEC J-STD-020. The device is classified as MSL Level 1, meaning unlimited floor life at ≤30°C/60% RH.

What is the cathode marking convention for ES3D?

The ES3D uses a single contrasting cathode band near one end of the DO-214AB body to identify the cathode terminal. This band aligns with the cathode pin in standard SMC footprints and matches the polarity marking shown in TSC's official package outline drawing (Version N2102). No alphanumeric marking is used for polarity identification.

Can ES3D replace ES3C or ES3F in an existing design?

ES3D (200 V) is not a direct replacement for ES3C (150 V) or ES3F (300 V) due to different V_RRM ratings. Substitution requires verification of worst-case reverse voltage stress in the circuit. While all share identical package, thermal specs, and t_rr, using ES3D in place of ES3F risks premature breakdown; using it instead of ES3C may over-specify voltage margin without benefit.
