Product details

Overview

S1DL from Taiwan Semiconductor is a 1 A, 200 V standard surface-mount silicon rectifier diode in Sub SMA package, featuring glass-passivated junction, low forward voltage (≤1.1 V at 1 A), and 1800 ns reverse recovery time - used in DC-DC converters and switching-mode power supplies for efficient unidirectional current control.

For engineers reviewing the S1DL datasheet, S1DL pinout, S1DL application, or S1DL equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current rating (30 A), thermal resistance (25 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for industrial and automotive-grade board-level integration.

Technical Context

The S1DL operates as a single-die, single-phase standard rectifier with cathode-band polarity marking and matte tin-plated leads solderable per J-STD-002. Its 200 V V_RRM and 1 A average forward current are rated over -55°C to +175°C junction temperature range.

Thermal performance is optimized for surface-mount use: R_θJL = 25 °C/W (S1AL–S1JL group), R_θJA = 85 °C/W, and junction capacitance is 9 pF at 1 MHz / 4 V reverse bias - supporting stable operation in high-frequency switching topologies.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in bridge or freewheeling configurations
I_F	1 A - continuous average forward current; determines steady-state power handling in linear or PWM-regulated supplies
I_FSM	30 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance
V_F	≤1.1 V @ 1 A, 25°C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle applications
t_rr	1800 ns - reverse recovery time affects switching losses and EMI in >20 kHz SMPS designs
T_J max	+175°C - maximum junction temperature enables high-ambient operation without derating in enclosed enclosures
C_J	9 pF @ 1 MHz, 4 V - low junction capacitance minimizes capacitive coupling and improves high-frequency rectification fidelity

Pinout & Package

Package: Sub SMA - low-profile, surface-mount plastic package with matte tin-plated leads, UL 94V-0 molding compound, and cathode band polarity indicator. Weight: 0.019 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Current entry terminal under forward bias	Connected to lower-potential side (e.g., switch node in buck converter); requires thermal relief pad for soldering reliability
Cathode	Current exit terminal under forward bias; marked by band	Connected to output rail or ground return path; band orientation must align with PCB silkscreen for automated placement verification

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR120	200 V V_RRM, 1 A I_F, but ultrafast t_rr = 75 ns; VF = 1.15 V; Sub SMA package	Better suited for higher-frequency (>500 kHz) SMPS where reverse recovery loss dominates	Select MUR120 when minimizing switching loss is critical; S1DL preferred for cost-sensitive, thermally stable 100–200 kHz designs
Vishay VS-1N4007-M3/54	1000 V V_RRM, same 1 A I_F, but DO-41 through-hole; t_rr > 2 µs; VF ≈ 1.1 V	Designed for legacy through-hole assembly; lacks moisture sensitivity certification and SMT optimization	Choose VS-1N4007-M3/54 only for repair or prototyping with through-hole boards; S1DL required for automated SMT production

Compared with MUR120 and VS-1N4007-M3/54, the S1DL balances cost, SMT manufacturability, and thermal robustness for mid-frequency industrial power conversion - offering J-STD-020 Level 1 handling, 25 °C/W junction-to-lead resistance, and verified 175°C operation without ultrafast trade-offs.

FAQ

What is the maximum repetitive peak reverse voltage rating for the S1DL?

The S1DL has a maximum repetitive peak reverse voltage (V_RRM) of 200 V, as specified in the absolute maximum ratings table for the S1xL family. This value is confirmed across all official Taiwan Semiconductor documentation versions (Q2108) and defines the highest reverse-bias voltage the device can block repeatedly without avalanche breakdown. Operating above 200 V risks irreversible junction failure. The S1DL is part of a scalable series where S1AL = 50 V and S1ML = 1000 V.

Does the S1DL have a defined reverse recovery time, and how is it measured?

Yes, the S1DL has a typical reverse recovery time (t_rr) of 1800 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is explicitly listed in the Electrical Specifications section of the Taiwan Semiconductor datasheet (Q2108). It reflects the time required for minority carriers to clear after forward conduction ceases - critical for estimating switching losses in SMPS circuits operating below 300 kHz.

Is the S1DL compliant with RoHS and halogen-free standards?

Yes, the S1DL is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Q2108). This compliance is verified for the entire S1xL series, including S1DL, and applies to both material content and manufacturing process. No exemptions are claimed, and the device carries full declaration documentation for export-controlled and eco-design-regulated markets.

What is the thermal resistance from junction to lead (R_θJL) for the S1DL?

The S1DL has a junction-to-lead thermal resistance (R_θJL) of 25 °C/W, as specified in the THERMAL PERFORMANCE section for the S1AL–S1JL subgroup. This value is confirmed in the Q2108 datasheet revision and reflects thermal conduction efficiency from the silicon die to the external lead frame under steady-state conditions. It enables accurate thermal modeling when the cathode/anode leads are used as primary heat paths in PCB layouts.

What marking code appears on the S1DL device body?

The S1DL is marked with "1DL" on its device body, as shown in the MARKING DIAGRAM and ABSOLUTE MAXIMUM RATINGS tables of the Taiwan Semiconductor datasheet (Q2108). This three-character laser marking distinguishes it within the S1xL family and corresponds directly to its 200 V V_RRM rating. The marking is located adjacent to the cathode band and is visible under standard optical inspection during AOI or manual QA.
