Product details
Overview
DSR01S30SL,L3F from Toshiba is a silicon epitaxial Schottky barrier diode optimized for high-speed switching, with 30 V reverse voltage rating, 100 mA average rectified current, 0.50 V max forward voltage at 10 mA, 0.7 µA max reverse current at 30 V, and 8.2 pF typical junction capacitance - used in compact DC-DC converter output rectification.
For engineers reviewing the DSR01S30SL,L3F datasheet, DSR01S30SL,L3F pinout, DSR01S30SL,L3F application, or DSR01S30SL,L3F equivalent, key selection criteria include low VF for efficiency, low IR for standby leakage control, SL2 package thermal performance, and suitability for space-constrained 100 kHz–1 MHz switching supplies.
Technical Context
This Schottky diode employs a planar silicon epitaxial structure to achieve fast recovery (no minority-carrier storage) and low forward conduction loss. Its low junction capacitance (8.2 pF typ.) and minimal reverse recovery charge support high-frequency operation up to 1 MHz without significant switching loss penalties.
The device operates with a maximum junction temperature of 125 °C and requires thermal derating above 25 °C ambient per Toshiba's reliability guidelines. Reverse leakage (IR ≤ 0.7 µA @ VR = 30 V) is specified under stable DC conditions, and thermal runaway mitigation must be addressed in layout due to inherent SBD leakage sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - sets maximum blocking capability in buck converter freewheeling or reverse-polarity protection paths |
| Forward Voltage (VF) | 0.50 V max @ IF = 10 mA - enables <50 mW conduction loss at 100 mA, critical for low-voltage, high-efficiency outputs |
| Reverse Current (IR) | 0.7 µA max @ VR = 30 V - defines worst-case standby power loss in always-on bias networks |
| Junction Capacitance (Ct) | 8.2 pF typ. @ VR = 0 V, f = 1 MHz - limits high-frequency displacement current and EMI generation in fast-switching nodes |
| Average Rectified Current (IO) | 100 mA - supports continuous output rectification in micro-power SMPS delivering up to ~1 W at 3.3–5 V |
| Peak Forward Surge Current (IFSM) | 2 A @ 10 ms pulse - withstands brief inrush or fault currents without bond-wire fusing |
Pinout & Package
DSR01S30SL,L3F is housed in the SL2 surface-mount package (Toshiba designation: 1-1AL1A), a miniature leadless chip-scale diode package measuring 1.2 × 0.8 × 0.5 mm, optimized for automated placement and thermal dissipation on small PCB pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Marked side) | Cathode | Connected to higher-potential node (e.g., switch node in buck topology); polarity marking aligns with cathode band |
| 2 | Anode | Connected to output rail or ground return path; serves as main current exit terminal during forward conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage | 0.50 V max @ 10 mA enables >90% efficiency in 3.3 V output converters with minimal thermal rise |
| Ultra-low reverse leakage | 0.7 µA max @ 30 V ensures sub-1 µW standby loss in battery-backed circuits |
| Miniature SL2 package | 1.2 × 0.8 mm footprint saves >60% board area vs. SOD-323, enabling ultra-dense power modules |
| High-speed zero-recovery | No minority-carrier storage eliminates reverse recovery tail, removing snubber requirements in 500 kHz+ designs |
Applications
| USB Power Delivery Interface | IoT Sensor Node Power Rail |
|---|---|
Use Scenario: Reverse-polarity and back-feed protection at USB-C port input, operating continuously at 5 V/100 mA. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from miswired cables or hot-plug transients.

Use Value: 30 V VR provides 2× margin over 5 V USB supply; SL2 size fits tight wearable PCB real estate constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RBS201T3G | Higher VF (0.55 V max @ 10 mA), same 30 V VR, SOD-523 package (1.7 × 0.9 mm) | Larger footprint; slightly lower efficiency in ultra-low-power rails | Preferred where SOD-523 reflow compatibility is required and 50 mV VF penalty is acceptable |
| NSR0130P2T5G | Lower IR (0.2 µA max @ 30 V), same VF spec, SOD-923 package (1.0 × 0.6 mm) | Smaller footprint but tighter assembly tolerance; lower leakage benefits long-term battery hold-up | Chosen when minimizing standby leakage dominates over VF trade-off and 0.2 mm² area savings justify fine-pitch placement |
Compared with DSR01S30SL,L3F, RBS201T3G offers broader distributor availability but sacrifices 50 mV forward drop and adds 0.5 mm² area; NSR0130P2T5G delivers superior leakage performance in a smaller outline but demands tighter process control - both require layout review for thermal and mechanical fit.

FAQ
What is the maximum junction temperature rating for DSR01S30SL,L3F?
The DSR01S30SL,L3F has a maximum junction temperature (Tj) rating of 125 °C. This limit applies under continuous operation with appropriate PCB thermal design - specifically, when mounted on a 25.4 mm × 25.4 mm × 1.6 mm glass epoxy board with 645 mm² copper pad area per Toshiba's absolute maximum ratings note. Exceeding this temperature accelerates parametric drift and reduces long-term reliability.
Does DSR01S30SL,L3F have a specified reverse recovery time (trr)?
No - DSR01S30SL,L3F does not specify reverse recovery time (trr) because it is a Schottky barrier diode with majority-carrier conduction. It exhibits zero reverse recovery charge (Qrr ≈ 0) and no minority-carrier storage delay. The device transitions instantly between conduction and blocking states, eliminating trr-related switching losses and snubber circuit needs in DSR01S30SL,L3F-based designs.
What is the marking code for DSR01S30SL,L3F on the SL2 package?
The DSR01S30SL,L3F is marked with a single black bar on the cathode end of the SL2 package. Per Toshiba documentation, this bar identifies Pin 1 as the cathode terminal. No alphanumeric laser marking is applied; polarity identification relies solely on the bar orientation relative to the rectangular die outline.
Can DSR01S30SL,L3F be used in automotive applications?
DSR01S30SL,L3F is not qualified to AEC-Q101 and is not recommended for automotive applications. Toshiba explicitly restricts its use in equipment for automobiles, citing "UNINTENDED USE" in their product disclaimer. For automotive-grade Schottky diodes, designers should select parts with formal AEC-Q101 qualification, extended temperature range (-40 to 150 °C), and PPAP documentation - DSR01S30SL,L3F lacks these certifications.
How does the SL2 package of DSR01S30SL,L3F compare thermally to SOD-323?
The SL2 package (1.2 × 0.8 mm) of DSR01S30SL,L3F provides lower thermal resistance than standard SOD-323 (1.7 × 1.3 mm) due to its thinner profile (0.5 mm vs. 0.9 mm) and direct die-to-PCB thermal path. Measured θJA is ~350 K/W on 645 mm² copper, versus ~420 K/W for typical SOD-323 - making DSR01S30SL,L3F better suited for sustained 100 mA loads in confined spaces.
