Product details
Overview
DSR01S30SC(TPL3) from Toshiba is a silicon epitaxial Schottky barrier diode optimized for high-speed switching applications, with 30 V reverse voltage rating, 100 mA average forward current (on FR4 board), and low forward voltage drop of 0.51 V at 100 mA. It serves as a rectifier or freewheeling diode in compact DC-DC converters and portable power supplies.
For engineers reviewing the DSR01S30SC(TPL3) datasheet, DSR01S30SC(TPL3) pinout, DSR01S30SC(TPL3) application, or DSR01S30SC(TPL3) equivalent, key selection criteria include its ultra-low VF at low currents, 8.2 pF junction capacitance, thermal stability up to 125°C junction temperature, and SC-2 package compatibility with space-constrained layouts.
Technical Context
This Schottky diode employs an epitaxial silicon structure to achieve fast recovery with negligible reverse recovery charge (Qrr), enabling efficient operation in high-frequency (>1 MHz) switching topologies. Its low forward voltage minimizes conduction loss, while the 0.7 μA max reverse leakage at 30 V supports stable performance in battery-powered systems.
The device operates reliably across −55°C to +125°C storage range and is rated for 2 A non-repetitive surge current. Thermal design must account for self-heating under continuous 100 mA load on standard FR4, per Toshiba's derating guidance in the Reliability Handbook.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability without breakdown; suitable for 24 V rail clamping and 5–12 V DC-DC output rectification. |
| Average Forward Current (IO) | 100 mA - Sustained DC current on standard FR4 PCB (25.4 × 25.4 × 1.6 mm, 645 mm² Cu pad); defines continuous power handling limit. |
| Forward Voltage (VF) | 0.51 V typ. at 100 mA - Low conduction loss reduces heat generation and improves efficiency in low-voltage, high-current paths. |
| Reverse Leakage (IR) | 0.7 μA max at VR = 30 V - Enables low standby power in always-on circuits and preserves battery life in portable devices. |
| Junction Capacitance (CT) | 8.2 pF at VR = 0 V, f = 1 MHz - Limits high-frequency switching noise and supports clean signal integrity in RF-adjacent power stages. |
| Junction Temperature (Tj) | 125°C - Specifies maximum allowable die temperature; requires thermal management when operating near IO limit at elevated ambient. |
Pinout & Package
DSR01S30SC(TPL3) is housed in the SC-2 (SOD-323) surface-mount package: 0.62 mm × 0.32 mm × 0.27 mm body, 0.19 mm lead pitch, cathode marked with band. Weight: 0.17 mg (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher-potential node during forward bias; polarity-sensitive terminal requiring correct PCB footprint orientation. |
| 2 | Anode | Connected to lower-potential node during forward conduction; forms current path with minimal voltage drop in rectification mode. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 0.37 V typ. at 10 mA - Reduces power loss in low-current bias networks and signal-level clamping. |
| High-speed switching | Negligible reverse recovery time - Eliminates Qrr-related losses and EMI in >500 kHz SMPS designs. |
| Low junction capacitance | 8.2 pF - Minimizes capacitive loading on high-frequency nodes and enables use in RF detector or mixer applications. |
| Thermal robustness | 125°C max junction temperature - Supports operation in sealed enclosures or near heat-generating ICs without derating. |
Applications
| USB Power Delivery Clamp | Portable Device LDO Bypass |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RBS1UA30ATR | Same VR (30 V), but 200 mA IO rating and 0.45 V VF at 100 mA; larger SOD-123 package (1.7 × 1.3 mm). | Higher current capability suits 150–200 mA loads; larger footprint increases board area by ~5×. | Select when higher surge tolerance or thermal margin is required; not suitable for ultra-dense layouts. |
| NSR0130P2T5G | Identical SC-2 package and 30 V VR; VF = 0.45 V typ. at 100 mA; IR = 1.0 μA max at 30 V - 43% higher leakage. | Lower VF improves efficiency, but higher IR may impact battery leakage in always-on sensor nodes. | Prefer for efficiency-critical 100 mA applications where leakage < 0.7 μA is not mandatory. |
Compared with RBS1UA30ATR and NSR0130P2T5G, DSR01S30SC(TPL3) offers the lowest reverse leakage (0.7 μA) in the SC-2 footprint, making it optimal for battery-sensitive, space-constrained designs where standby current and board area are primary constraints.

FAQ
What is the maximum continuous forward current rating for DSR01S30SC(TPL3)?
The DSR01S30SC(TPL3) is rated for 100 mA average forward current when mounted on a standard FR4 board (25.4 mm × 25.4 mm × 1.6 mm with 645 mm² copper pad). This rating assumes Ta = 25°C and requires thermal derating above 25°C ambient per Toshiba's Reliability Handbook guidelines. Exceeding this current without adequate heatsinking risks accelerated degradation.
Does DSR01S30SC(TPL3) have a specified reverse recovery time?
No, the DSR01S30SC(TPL3) datasheet does not specify reverse recovery time (trr) because it is a Schottky barrier diode with majority-carrier conduction. It exhibits negligible reverse recovery charge (Qrr), enabling use in high-frequency switching applications without trr-related losses or ringing. This behavior is inherent to its epitaxial silicon Schottky construction.
What is the marking code for DSR01S30SC(TPL3) on the device body?
The DSR01S30SC(TPL3) is marked "1-1R1A" on the top surface per JEITA standard. This marking identifies the device variant and is visible under magnification on the SC-2 package. The cathode is indicated by a band adjacent to pin 1, consistent with the top-view pinout diagram in the official Toshiba datasheet.
Is DSR01S30SC(TPL3) suitable for automotive applications?
The DSR01S30SC(TPL3) is not qualified to AEC-Q101 or automotive-grade reliability standards. Toshiba explicitly restricts its use in automotive systems per the "Restrictions on Product Use" section. For automotive applications, engineers must select components explicitly certified for automotive environments and consult Toshiba's automotive-qualified Schottky diode portfolio.
How does the junction capacitance of DSR01S30SC(TPL3) affect high-frequency performance?
The DSR01S30SC(TPL3) has a typical junction capacitance of 8.2 pF at VR = 0 V and f = 1 MHz. This low CT value minimizes capacitive loading on switching nodes, reducing EMI generation and preserving signal edge rates in high-frequency DC-DC converters and RF-adjacent power circuits. It also enables effective clamping without distorting fast transients.
