Product details

Overview

ES2DAL from Taiwan Semiconductor is a 2 A, 200 V super fast surface-mount rectifier in a Thin SMA package, featuring 35 ns reverse recovery time, 0.88 V forward voltage at 2 A/25°C, and 24 °C/W junction-to-lead thermal resistance-designed for high-frequency DC-DC converters and freewheeling paths in switching power supplies.

For engineers reviewing the ES2DAL datasheet, ES2DAL pinout, ES2DAL application, or ES2DAL equivalent, key selection criteria include its 200 V repetitive peak reverse voltage, low-profile Thin SMA footprint, 50 A surge rating, and verified performance at 125°C junction temperature in compact power conversion designs.

Technical Context

The ES2DAL employs a single-die, glass-passivated silicon junction optimized for super-fast switching with minimal stored charge. Its 35 ns reverse recovery time and 28 pF junction capacitance at 4 V support operation in high-frequency (>100 kHz) SMPS topologies without excessive switching loss or ringing.

Thermally, the device delivers R_θJL = 24 °C/W and R_θJA = 72 °C/W when mounted on a 5 mm × 5 mm copper pad, enabling reliable 2 A continuous conduction in space-constrained industrial and consumer power modules.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02	Same 2 A / 200 V rating; 30 ns t_rr, 0.92 V V_F @ 2 A; TO-277 package (higher profile, higher R_θJA)	Requires larger PCB footprint and additional thermal relief; better suited for higher ambient temp (>85°C) with heatsink.	Select STTH2R02 only if lower t_rr is prioritized over board space and assembly compatibility.
MBR2200	Schottky construction; 0.82 V V_F @ 2 A but limited to 200 V max; no reverse recovery (t_rr = 0 ns); higher leakage (~100 µA @ 125°C)	Not suitable for high-voltage transient environments; preferred in low-noise, low-loss 12–48 V systems where reverse leakage is tolerable.	Choose MBR2200 only when minimizing conduction loss dominates over reverse leakage and voltage margin requirements.

Compared with STTH2R02 and MBR2200, the ES2DAL offers optimal balance of speed (35 ns), low profile (Thin SMA), and robustness (150°C T_JMAX, 50 A I_FSM) for space-constrained, medium-voltage SMPS where Schottky leakage or TO-277 height are unacceptable.

FAQ

What is the maximum junction temperature rating for ES2DAL?

The ES2DAL has a maximum junction temperature (T_JMAX) of +150°C, validated per absolute maximum ratings in the official TSC datasheet Version D2103. This rating allows continuous operation in thermally demanding environments such as enclosed industrial power supplies or automotive under-hood auxiliary converters, provided thermal design maintains actual junction temperature below this limit. Derating curves confirm usable current capacity down to 1.2 A at 125°C ambient with standard PCB mounting.

Does ES2DAL have a specified reverse recovery time, and how is it measured?

Yes, ES2DAL specifies a reverse recovery time (t_rr) of 35 ns maximum, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A, per JEDEC test methods. This value is confirmed in the Electrical Specifications table of the TSC ES2BAL–ES2JAL datasheet (Version D2103). The 35 ns t_rr directly impacts switching loss and EMI in high-frequency converters, making it a critical parameter for layout and gate-drive timing design.

What is the forward voltage of ES2DAL at 2 A and 125°C junction temperature?

The forward voltage (V_F) of ES2DAL is 0.74 V typical at 2 A and 125°C junction temperature, as published in the Electrical Specifications table of the TSC datasheet (Version D2103). This reduced V_F versus room temperature (0.88 V) reflects positive temperature coefficient behavior of the silicon PN junction, aiding current sharing in parallel configurations and easing thermal runaway concerns in multi-diode arrays.

Is ES2DAL RoHS and halogen-free compliant?

Yes, ES2DAL is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the FEATURES section of the TSC ES2BAL–ES2JAL datasheet (Version D2103). The molding compound meets UL 94V-0 flammability rating, and terminals are matte tin plated per J-STD-002, supporting lead-free reflow soldering and environmental compliance for global electronics markets including EU and China RoHS.

What does the marking code 'ES2DAL' indicate on the device body?

The marking code 'ES2DAL' laser-etched on the ES2DAL device body identifies the exact part number per TSC's ordering nomenclature, where 'D' denotes the 200 V V_RRM variant within the ES2xAL family. It is distinct from ES2BAL (100 V), ES2GAL (400 V), and ES2JAL (600 V). The cathode band adjacent to the marking provides unambiguous polarity identification for automated optical inspection and pick-and-place alignment during SMT assembly.
