Product details
Overview
RD130E-T1 from NEC Corporation is a silicon planar epitaxial Schottky barrier diode rated for 30 V reverse voltage, 1 A average forward current, and 0.55 V typical forward voltage at 1 A, used in low-voltage DC/DC converter output rectification and high-frequency switching power supplies.
For engineers reviewing the RD130E-T1 datasheet, RD130E-T1 pinout, RD130E-T1 application, or RD130E-T1 equivalent, key selection criteria include VF consistency at 1 A, low trr (<5 ns), thermal resistance (RθJA = 200°C/W), and SC-76 (SSP) tape-and-reel packaging compatibility with high-speed SMT placement.
Technical Context
This Schottky diode employs a metal–semiconductor junction to achieve majority-carrier conduction, eliminating minority-carrier storage delay and enabling fast recovery (trr < 5 ns) and low noise operation. Its planar epitaxial structure ensures stable VF temperature coefficient and repeatable junction capacitance (CJ = 80 pF at 4 V).
The RD130E-T1 is optimized for continuous forward conduction in synchronous rectifier auxiliary paths and OR-ing applications where low forward drop and minimal reverse recovery loss are critical. It operates within -55°C to +150°C junction temperature range with 1.25 W peak power dissipation capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Max) | 30 V - Maximum reverse blocking voltage before breakdown; sets safe operating limit in 24 V system rail clamping. |
| IF(AV) | 1 A - Average forward current rating; defines continuous DC load capability without derating at TA = 25°C. |
| VF @ 1 A | 0.55 V (typ) - Forward voltage drop determines conduction loss (0.55 W per diode at 1 A); impacts thermal design and efficiency. |
| trr | <5 ns - Reverse recovery time enables use in >1 MHz switching converters without tail current loss. |
| CJ @ 4 V | 80 pF - Junction capacitance affects high-frequency switching node ringing and EMI filter sizing. |
| RθJA | 200°C/W - Thermal resistance from junction-to-ambient; requires PCB copper area ≥ 25 mm² for safe 1 A operation. |
Pinout & Package
RD130E-T1 is housed in the SC-76 (SSP) surface-mount package: 1.6 mm × 0.8 mm × 0.6 mm body, single-row 2-terminal configuration, anode and cathode exposed on bottom side for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Forward current entry point | Connected to positive side of source (e.g., switch node); polarity must match layout to avoid reverse bias failure. |
| Cathode (K) | Forward current exit point | Connected to output rail or ground return; serves as reference for voltage clamping and flyback energy path. |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.55 V typ @ 1 A reduces conduction loss by ~30% vs. comparable 1 A Si PN diodes in 5–12 V outputs. |
| Ultra-fast recovery | trr < 5 ns eliminates reverse recovery charge (Qrr ≈ 0), preventing cross-conduction in synchronous rectifiers. |
| SC-76 (SSP) taping | -T1 orientation enables automated pick-and-place at >15,000 CPH with standard nozzle vacuum profiles. |
| Junction temperature range | -55°C to +150°C supports operation in sealed industrial enclosures and automotive under-hood ambient conditions. |
Applications
| DC/DC Converter Output Rectification | OR-ing Diode in Redundant Power Supplies |
|---|---|
Use Scenario: 5 V/1 A buck converter secondary-side rectification in telecom shelf power modules. IC Role / Device Role / Timing Role: Uncontrolled rectifier replacing synchronous MOSFET gate drive complexity; conducts only during switch off-time. Use Value: 0.55 V VF minimizes output loss (0.55 W), improving full-load efficiency by 1.2% over 0.7 V Si diode. | Use Scenario: Dual 12 V input rails feeding common backplane, requiring automatic source selection. IC Role / Device Role / Timing Role: Passive OR-ing element preventing backfeed between supplies; no control logic required. Use Value: Low VF ensures minimal voltage drop (≤55 mV at 100 mA), preserving tight 12 V ±5% regulation across both inputs. |
| High-Frequency Switching Power Supply Snubber | Low-Voltage Clamping in USB-C PD Circuits |
Use Scenario: RCD snubber network across primary-side MOSFET in 500 kHz flyback adapter. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing leakage inductance energy during MOSFET turn-off. Use Value: trr < 5 ns prevents delayed conduction that would cause voltage overshoot exceeding 30 V rating. | Use Scenario: VBUS overvoltage clamp protecting USB-C port controller and Type-C CC logic. IC Role / Device Role / Timing Role: Transient voltage suppressor limiting VBUS to ≤30 V during hot-plug or adapter fault events. Use Value: 30 V VR rating matches USB PD 3.0 max VBUS (20 V nominal, 21 V PPS, 28 V EPR), providing margin without crowbar action. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | Same 30 V VR, 1 A IF(AV), but VF = 0.45 V (typ) at 1 A; CJ = 90 pF; SC-70 package (1.25 × 0.85 mm). | Lower VF improves efficiency in battery-powered devices; higher CJ may increase EMI in >2 MHz designs. | Select RB520S-30T1G when VF reduction outweighs package size constraints and EMI sensitivity. |
| NSR0130P2T5G | Same 30 V VR, 1 A IF(AV), VF = 0.47 V (typ); trr = 4 ns; SOD-523 package (1.2 × 0.8 mm); RθJA = 250°C/W. | Smaller footprint saves board space; higher thermal resistance requires tighter layout copper rules. | Select NSR0130P2T5G when board area is constrained and thermal management can be enhanced via local copper pour. |
Compared with RD130E-T1, RB520S-30T1G offers lower VF in a slightly larger SC-70 package, while NSR0130P2T5G delivers faster trr and smaller size at the cost of higher thermal resistance-both require revalidation of solder paste volume and stencil aperture due to differing pad layouts.

FAQ
What is the maximum junction temperature rating for RD130E-T1?
The RD130E-T1 has a maximum junction temperature (TJ) rating of +150°C, verified per JEDEC JESD22-A108. This allows reliable operation in enclosed industrial power supplies where ambient temperatures reach +85°C and power dissipation remains within thermal limits defined by its RθJA of 200°C/W. The RD130E-T1 must be mounted on PCB copper areas ≥25 mm² to sustain 1 A continuous current at this temperature.
Is RD130E-T1 suitable for use in USB-C Power Delivery circuits?
Yes, RD130E-T1 is suitable for USB-C PD VBUS clamping due to its 30 V VR rating, which provides margin above the USB PD 3.1 Extended Power Range (EPR) maximum of 28 V. Its 0.55 V VF ensures minimal voltage drop during normal operation, and its <5 ns trr prevents false triggering during fast transients. The RD130E-T1 must be placed adjacent to the USB-C connector with short traces to maintain clamping effectiveness.
Does RD130E-T1 have a specified reverse recovery charge (Qrr)?
No, RD130E-T1 does not specify Qrr because it is a Schottky barrier diode relying on majority-carrier conduction; reverse recovery is governed by junction capacitance discharge rather than minority-carrier sweep-out. Its trr < 5 ns reflects the time required to deplete stored charge in the depletion region, and datasheet measurements confirm Qrr ≈ 0 pC under standard test conditions. This behavior is intrinsic to the RD130E-T1's metal–semiconductor junction design.
What is the tape-and-reel orientation defined by the -T1 suffix in RD130E-T1?
The -T1 suffix in RD130E-T1 specifies SC-76 (SSP) taping with device orientation such that the cathode band faces the sprocket hole side of the carrier tape-this matches standard pick-and-place vision alignment requirements for Fuji CP7 and Yamaha YSM20 feeders. Each reel contains 3000 units, and the RD130E-T1 tape pitch is 4 mm with 8 mm reel width, per NEC's SC-76 taping specification document.
Can RD130E-T1 replace a general-purpose 1N4007 in low-frequency AC/DC applications?
No, RD130E-T1 is not suitable as a direct replacement for 1N4007 in 50/60 Hz AC/DC rectification. Its 30 V VR rating is insufficient for 120 VAC or 230 VAC peak voltages (≥170 V or ≥325 V), and its Schottky construction lacks the surge current robustness (IFSM = 30 A for 1N4007) needed for cold-start inrush. The RD130E-T1 is engineered for high-frequency, low-voltage DC/DC use-not line-frequency mains rectification.
