Product details
Overview
RD16S-T2 from NEC Corporation is a silicon planar epitaxial Schottky barrier diode in SC-76 (SSP) package, rated for 16 V reverse voltage and 30 mA average forward current, with 0.55 V typical forward voltage at 10 mA, used in low-power signal rectification and polarity protection circuits.
For engineers reviewing the RD16S-T2 datasheet, RD16S-T2 pinout, RD16S-T2 application, or RD16S-T2 equivalent, key selection criteria include low VF for minimal conduction loss, small SC-76 footprint for space-constrained designs, and reliable taping orientation (-T2) for automated SMT placement.
Technical Context
The RD16S-T2 implements a single Schottky junction optimized for low forward voltage drop and fast switching response, with no stored charge recovery delay. Its epitaxial structure ensures stable performance across -40°C to +125°C operating temperature range.
This device operates as a unidirectional conductor with anode-cathode polarity defined by physical marking on the SC-76 case. It is not designed for avalanche energy handling or bidirectional conduction.
Key Specifications

Pinout & Package
SC-76 (SSP) is a 2-terminal surface-mount package with cathode marked by a band on the top surface. Terminal 1 (anode) and Terminal 2 (cathode) are arranged linearly along the long axis of the 1.3 × 0.8 mm body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

IC Role / Device Role / Timing Role: Clamp diode tied between signal line and 3.3 V rail to shunt excess positive excursion. Use Value: Low IR (10 µA max.) avoids loading sensitive high-impedance sensor outputs during normal operation. |

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 | Higher VR = 30 V; VF = 0.33 V typ. at 10 mA; same SC-76 package | Better suited for 24 V industrial IO where higher reverse margin is required | Select RB520S-30T1G when system reverse stress exceeds 16 V or ultra-low VF is critical |
| NSR0330HT1G | Same VR = 30 V; VF = 0.45 V typ. at 10 mA; SC-70 package (1.25 × 0.85 mm) | Compatible footprint but slightly larger body; tighter thermal resistance (190°C/W vs. 220°C/W) | Choose NSR0330HT1G if board layout allows SC-70 and improved thermal margin is needed |
Compared with RD16S-T2, RB520S-30T1G offers higher reverse voltage headroom and lower VF, while NSR0330HT1G provides identical voltage rating with better thermal performance in a near-equivalent footprint-both require validation of taping orientation and solder profile compatibility.

FAQ
What is the maximum reverse voltage rating for RD16S-T2?
The RD16S-T2 has a maximum repetitive peak reverse voltage (VRRM) of 16 V. This rating defines the highest DC or sinusoidal reverse voltage the device can block continuously without entering breakdown. Exceeding this value risks irreversible junction failure. The RD16S-T2 must not be used in circuits where transient or steady-state reverse voltage exceeds 16 V.
Does RD16S-T2 have a specified junction-to-ambient thermal resistance?
Yes, the RD16S-T2 has a typical junction-to-ambient thermal resistance (RθJA) of 220°C/W under standard JEDEC test conditions (1 cm² copper pad, FR-4 board). This value determines temperature rise above ambient at a given power dissipation. For RD16S-T2 operating at 30 mA and 0.55 V VF, power dissipation is ~16.5 mW, resulting in ~3.6°C rise - well within safe limits.
Is RD16S-T2 compatible with lead-free reflow soldering processes?
Yes, RD16S-T2 is qualified for lead-free reflow soldering per J-STD-020. Its SC-76 (SSP) package uses matte tin plating and withstands peak temperatures up to 260°C for 10 seconds. The RD16S-T2 must be stored per MSL level 1 requirements and processed using standard Pb-free thermal profiles without delamination or bond integrity loss.
What does the "-T2" suffix indicate in RD16S-T2?
The "-T2" suffix specifies the tape-and-reel orientation per NEC's SC-76 taping standard: devices are oriented with cathode band facing the sprocket hole side of the carrier tape. This differs from "-T1", where the band faces away. Correct orientation is essential for accurate vision-based pick-and-place placement. RD16S-T2 reels contain 3,000 units per standard 13-inch reel.
Can RD16S-T2 be used as a replacement for general-purpose 1N4148 diodes?
No, RD16S-T2 is not a direct replacement for 1N4148. While both are small-signal diodes, the 1N4148 is a silicon switching diode (100 V VR, 250 mA IF), whereas RD16S-T2 is a Schottky diode (16 V VR, 30 mA IF) with lower VF but no avalanche rating. Substituting RD16S-T2 in 1N4148 applications risks reverse breakdown or insufficient current capacity. Use RD16S-T2 only where its specific Schottky characteristics are required.
