Product details
Overview
RD16E(5) from NEC Corporation is a silicon epitaxial planar Schottky barrier diode optimized for high-frequency switching applications, with 16 V reverse voltage rating, 500 mA average forward current, and low 0.45 V typical forward voltage at 500 mA, used in DC-DC converter output rectification.
For engineers reviewing the RD16E(5) datasheet, RD16E(5) pinout, RD16E(5) application, or RD16E(5) equivalent, key selection criteria include VF vs. IF performance at 100 kHz–1 MHz switching frequencies, thermal resistance in SC-76 (SSP) package, and compatibility with automated SMT placement using -T1/-T2 taping orientation.
Technical Context
The RD16E(5) employs a silicon epitaxial planar structure to achieve fast recovery with negligible reverse recovery charge (Qrr ≈ 0 nC), enabling efficient operation in synchronous rectifier and flyback converter topologies. Its low junction capacitance (Cj = 30 pF at VR = 4 V) supports stable high-frequency waveform integrity.
Designed for surface-mount assembly, the device uses an SC-76 (SSP) leadless package with single-anode/single-cathode terminal configuration and thermal pad exposed on underside for enhanced PCB heat dissipation under continuous 500 mA load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR - Repetitive Peak Reverse Voltage | 16 V - Maximum allowable reverse bias before breakdown in DC-DC output stage |
| IF(AV) - Average Forward Current | 500 mA - Continuous DC current handling capability at TA = 75 °C with PCB copper area ≥ 25 mm² |
| VF - Forward Voltage | 0.45 V typ. at IF = 500 mA - Directly reduces conduction loss in 3.3 V/5 V buck converter outputs |
| IR - Reverse Current | 100 µA max. at VR = 16 V, TA = 25 °C - Limits standby power leakage in always-on power rails |
| Cj - Junction Capacitance | 30 pF at VR = 4 V - Minimizes capacitive coupling noise in 500 kHz–1 MHz switching nodes |
| trr - Reverse Recovery Time | Not applicable - Schottky construction eliminates minority-carrier storage delay |
Pinout & Package
RD16E(5) is housed in SC-76 (SSP), a 2-terminal leadless surface-mount package with cathode marked by molded notch and thermal pad on underside for soldered thermal interface to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to switch node (e.g., MOSFET drain) in synchronous rectifier configuration |
| Cathode | Forward current exit point | Connected to output rail and bulk capacitor; serves as reference for feedback sensing |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | 0.45 V typ. at 500 mA enables >92% efficiency in 5 V → 3.3 V buck converters |
| Ultra-fast switching | No reverse recovery charge allows clean turn-off at 1 MHz without snubber networks |
| SC-76 (SSP) package | 1.6 × 1.6 × 0.55 mm footprint supports high-density layout in space-constrained IoT power modules |
| Tape-and-reel compatible | -T1/-T2 taping variants enable direct integration into Juki/Fuji SMT pick-and-place feeders |
Applications
| Server VRM Output Rectification | USB-C PD Adapter Secondary Side |
|---|---|
Use Scenario: 12 V input to 3.3 V/5 V/12 V multi-rail VRM supplying CPU/GPU core logic. IC Role / Device Role / Timing Role: Synchronous rectifier diode replacing MOSFET gate drive complexity in secondary-side synchronous rectification.

IC Role / Device Role / Timing Role: Output rectifier in flyback or active-clamp forward topology operating at 100–300 kHz. Use Value: 30 pF Cj minimizes EMI generation during switching transitions, easing CISPR-32 Class B compliance. |
| Industrial PLC Power Supply | Smart Meter Auxiliary Rail Generation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode rectification applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VR = 30 V; VF = 0.47 V at 500 mA; same SC-76 (SSP) footprint | Preferred where input transient protection requires >16 V reverse margin | Select RB050M-30TR if system-level surge testing mandates ≥25 V VR headroom |
| NSR0530HT1G | VF = 0.41 V typ. at 500 mA; VR = 30 V; slightly higher Cj = 40 pF | Better efficiency in low-VF-critical 3.3 V rails; less optimal for EMI-sensitive 100+ kHz designs | Choose NSR0530HT1G when maximizing light-load efficiency outweighs EMI filtering cost |
Compared with RD16E(5), RB050M-30TR offers higher reverse voltage margin at minor VF penalty, while NSR0530HT1G trades 5 pF higher capacitance for 0.04 V lower forward drop-enabling trade-offs between transient robustness, conduction loss, and EMI filter sizing.

FAQ
What is the maximum junction temperature rating for RD16E(5)?
The RD16E(5) has a maximum junction temperature (Tj) rating of 125 °C. This limit is defined under steady-state thermal conditions with adequate PCB copper area (≥25 mm² per terminal) and ambient temperature ≤75 °C. Exceeding 125 °C risks permanent degradation of the Schottky barrier interface, directly impacting RD16E(5) reliability in high-power-density applications.
Does RD16E(5) support automatic optical inspection (AOI) after reflow?
Yes, RD16E(5) supports AOI post-reflow due to its SC-76 (SSP) package geometry and consistent cathode marking via molded notch. The flat, coplanar terminals and absence of leads allow reliable solder-joint inspection under standard 10 µm resolution AOI systems. RD16E(5)'s thermal pad also provides uniform reflectivity, reducing false-negative detection rates in production line AOI validation.
Is RD16E(5) compliant with RoHS and REACH regulations?
RD16E(5) complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by NEC's material declarations archived prior to the Renesas merger. Lead content is below 1000 ppm, and no SVHC substances above threshold are present in RD16E(5)'s die, metallization, or molding compound-ensuring RD16E(5) suitability for global commercial and industrial markets.
Can RD16E(5) be used in parallel configurations for higher current handling?
RD16E(5) is not recommended for parallel operation due to forward voltage mismatch (±5% typical) causing current imbalance and localized thermal runaway. Even with matched binning, thermal coupling differences across PCB pads result in unequal junction temperatures. For >500 mA requirements, select a single higher-rated device such as RD20E(5) rather than paralleling RD16E(5) units.
What taping variants are available for RD16E(5)?
RD16E(5) is supplied in two tape-and-reel orientations: -T1 and -T2, differentiated by device rotation direction relative to sprocket holes. Both use standard 8 mm carrier tape with 3000 units per reel and comply with EIA-481-D. The choice between -T1 and -T2 depends on feeder compatibility-RD16E(5) must match the pick-and-place machine's vision alignment algorithm to ensure correct anode/cathode orientation during placement.
