Product details

Overview

S2DA-T from Taiwan Semiconductor is a 2 A, 200 V standard surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring glass passivated junction, low reverse leakage (≤5 µA at 25°C), and 50 A surge capability - used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the S2DA-T datasheet, S2DA-T pinout, S2DA-T application, or S2DA-T equivalent, key selection criteria include repetitive peak reverse voltage (200 V), forward voltage (0.96 V max at 2 A/25°C), thermal resistance (R_θJL = 14 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance.

Technical Context

The S2DA-T is a single-die, unidirectional standard recovery rectifier optimized for general-purpose and switching-mode power conversion. Its glass-passivated junction ensures stable reverse characteristics and moisture resistance (J-STD-020 Level 1), while the DO-214AC (SMA) package supports automated placement and soldering per J-STD-002.

Thermal performance is characterized with R_θJA = 86 °C/W on a 5 mm × 5 mm Cu pad PCB, and R_θJC = 23 °C/W. Electrical behavior includes typical junction capacitance of 30 pF at 1 MHz/4 V and reverse current rising from ≤5 µA at 25°C to ≤100 µA at 125°C under rated V_RRM.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage the device blocks without breakdown
I_F	2 A - continuous average forward current rating at TA = 75°C (derated above)
I_FSM	50 A - non-repetitive surge current (8.3 ms half-sine) the device withstands without failure
V_F	0.96 V max at 2 A/25°C - forward voltage drop directly impacts conduction loss in power stages
R_θJL	14 °C/W - junction-to-lead thermal resistance determines heat transfer efficiency to PCB copper
T_J max	+150 °C - maximum allowable junction temperature defines safe operating margin under load
I_R	≤5 µA at 25°C - low reverse leakage preserves efficiency in high-impedance bias networks

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02	2 A, 200 V, TO-220AC package; higher R_θJA (~50 °C/W), VF ≈ 0.95 V @ 2 A	Through-hole mounting; unsuitable for space-constrained SMT designs	Select when board-level thermal management favors through-hole heatsinking or legacy footprint reuse
ES2D	2 A, 200 V, DO-214AC (SMA); faster recovery (t_rr ≈ 35 ns vs. S2DA-T's ~2 µs), VF ≈ 0.92 V @ 2 A	Higher cost; preferred in higher-frequency SMPS (>100 kHz) where reverse recovery loss matters	Select when operating frequency exceeds 50 kHz or EMI reduction via faster recovery is required

Compared with STTH2R02 and ES2D, the S2DA-T offers lowest cost and smallest footprint among 2 A/200 V rectifiers, with thermal performance optimized for SMT PCB copper spreading rather than heatsinks or high-frequency switching trade-offs.

FAQ

What is the maximum junction temperature rating for the S2DA-T?

The S2DA-T has a maximum junction temperature (T_J) rating of +150 °C, with an operational range from –55 °C to +150 °C. This allows reliable use in enclosed industrial power supplies and automotive under-hood auxiliary circuits where ambient temperatures exceed 85 °C. Derating curves in the datasheet define usable forward current versus case temperature, and the S2DA-T must be mounted on appropriate PCB copper area to maintain T_J ≤ 150 °C under full load.

Does the S2DA-T have a specified reverse recovery time (t_rr)?

No, the S2DA-T datasheet does not specify reverse recovery time (t_rr) because it is a standard recovery rectifier, not a fast or ultrafast type. Its recovery behavior is characterized by typical junction capacitance (30 pF) and reverse current (≤5 µA at 25°C), making it suitable for line-frequency and low-to-moderate frequency (<50 kHz) switching applications. For t_rr-critical designs, consider alternatives like ES2D or MUR220.

Is the S2DA-T RoHS and halogen-free compliant?

Yes, the S2DA-T is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are matte tin plated per J-STD-002. These attributes are confirmed in the official Taiwan Semiconductor D2111 datasheet revision and apply specifically to the S2DA-T variant, supporting compliance in consumer, industrial, and medical-adjacent equipment.

What is the marking code printed on the S2DA-T device body?

The S2DA-T is marked "S2DA" on the device body, followed by green compound (G), date code (YW), and factory code (F) per the official marking diagram. This distinguishes it from other family members (e.g., S2GA-T = "S2GA"). The cathode is indicated by a visible band adjacent to the marking, confirming polarity orientation during PCB layout and assembly.

Can the S2DA-T replace the S2AA-T in a design?

No, the S2DA-T cannot directly replace the S2AA-T. While both share the DO-214AC (SMA) package and 2 A rating, the S2AA-T has a 50 V V_RRM, whereas the S2DA-T is rated for 200 V. Substituting the S2DA-T in a 50 V circuit introduces unnecessary voltage overhead and potential cost/size penalty; substituting the S2AA-T in a 200 V application risks catastrophic reverse breakdown. Always match V_RRM to system voltage stress requirements.
