Product details
Overview
RD16S(0)-T1-AT from NEC Corporation is a silicon planar epitaxial Zener diode in SC-76 (SSP) package, rated for 16 V nominal Zener voltage at 5 mA test current, with 5% tolerance and 500 mW power dissipation, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the RD16S(0)-T1-AT datasheet, RD16S(0)-T1-AT pinout, RD16S(0)-T1-AT application, or RD16S(0)-T1-AT equivalent, key selection criteria include Zener voltage accuracy, temperature coefficient, dynamic impedance, maximum reverse leakage, and SC-76 tape-and-reel packaging compatibility with automated SMT placement systems.
Technical Context
This Zener diode operates in reverse breakdown mode with stable voltage regulation across its specified current range (1–20 mA). Its SC-76 (SSP) surface-mount package features a single anode-cathode terminal pair and supports reflow soldering per J-STD-020.
The -T1 taping orientation specifies device alignment on carrier tape with cathode band facing the sprocket holes, enabling consistent pick-and-place registration. The "AT" suffix indicates automotive-grade qualification per AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±5% at IZ = 5 mA - defines regulated output voltage under standard test condition |
| Power Dissipation (PZM) | 500 mW - maximum steady-state power the device can safely dissipate at 25°C ambient |
| Zener Impedance (ZZT) | 40 Ω max at IZ = 5 mA - limits output voltage variation under changing load current |
| Reverse Leakage (IR) | 100 nA max at VR = 12 V - ensures minimal standby current in voltage-sense or clamp circuits |
| Temperature Coefficient (TC) | +0.08 %/°C typical - quantifies VZ drift over operating temperature range (−65°C to +150°C) |
| Package | SC-76 (SSP) - 2-pin ultra-small surface-mount outline (1.2 × 0.8 × 0.6 mm), compatible with 8 mm tape |
Pinout & Package
SC-76 (SSP) is a two-terminal surface-mount package with cathode marked by a band on the top surface. The device has no internal leads; terminals are formed by metallized pads on opposite ends of the molded body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node in shunt regulator | Connected to circuit ground or lower-potential node; carries reverse current during Zener operation |
| Cathode | Regulated output terminal / Voltage reference node | Connected to input supply or protected node; maintains stable 16 V relative to anode when reverse-biased above knee voltage |
Key Features
| Feature | Design Value |
|---|---|
| High Zener voltage accuracy | ±5% tolerance enables use in 16 V reference designs without post-calibration trimming |
| Low dynamic impedance | 40 Ω max ensures <100 mV output shift across 1–10 mA load current changes |
| Automotive qualification | AEC-Q101 qualified (-AT suffix) confirms reliability for under-hood and infotainment power rail monitoring |
| SC-76 tape-and-reel compatibility | -T1 taping orientation guarantees repeatable machine vision detection and placement in high-speed SMT lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16LT1G | Same 16 V ±5%, but SOT-23 package (2.9 × 1.3 mm); ZZT = 40 Ω max; IR = 100 nA max at 12 V | Larger footprint; not SC-76 tape-compatible; requires different feeder setup | Choose if board space allows larger package and existing SOT-23 feeders are in use |
| MMSZ4687T1G | 16 V ±5%, SOD-123 package (3.7 × 1.6 mm); PZM = 500 mW; TC = +0.085 %/°C | Higher thermal mass; slower transient response; incompatible with SC-76 reel handling | Prefer when higher surge robustness is needed and tape orientation flexibility is acceptable |
Compared with BZX84-C16LT1G and MMSZ4687T1G, RD16S(0)-T1-AT offers the smallest footprint and guaranteed -T1 tape orientation for high-throughput placement-critical where PCB real estate and SMT line efficiency are constrained.

FAQ
What is the Zener voltage tolerance specification for RD16S(0)-T1-AT?
The RD16S(0)-T1-AT has a Zener voltage tolerance of ±5% at 5 mA test current, meaning its actual breakdown voltage falls between 15.2 V and 16.8 V under standard conditions. This tolerance is verified per NEC's production test flow and applies to all units shipped with the -AT automotive qualification suffix. RD16S(0)-T1-AT maintains this spec across its full operating temperature range.
Does RD16S(0)-T1-AT support lead-free reflow soldering?
Yes, RD16S(0)-T1-AT is qualified for lead-free reflow soldering per J-STD-020 revision D, with peak temperature up to 260°C for 30 seconds. Its SC-76 (SSP) package uses matte tin plating on terminations and meets JEDEC MSL Level 1 requirements. RD16S(0)-T1-AT does not require pre-baking prior to assembly.
What does the "-T1" in RD16S(0)-T1-AT indicate?
The "-T1" suffix in RD16S(0)-T1-AT specifies the taping orientation on the carrier tape: devices are placed with the cathode band aligned toward the sprocket holes, ensuring consistent optical recognition and mechanical pickup during automated placement. RD16S(0)-T1-AT reels contain 3,000 units per 8 mm tape, conforming to EIA-481-D standards.
Is RD16S(0)-T1-AT suitable for overvoltage protection in automotive LIN bus systems?
Yes, RD16S(0)-T1-AT is AEC-Q101 qualified and commonly used as a clamp diode on 12 V LIN bus power rails. Its 16 V Zener voltage provides margin above nominal 12 V while clamping transients up to 16.8 V. RD16S(0)-T1-AT's low leakage and tight tolerance ensure reliable operation during ISO 16750-2 Pulse 5a load-dump tests.
How does the temperature coefficient of RD16S(0)-T1-AT affect long-term voltage reference stability?
RD16S(0)-T1-AT has a typical temperature coefficient of +0.08 %/°C, resulting in approximately ±128 mV drift over a −40°C to +125°C range. This enables stable 16 V referencing in thermally variable environments without external compensation. RD16S(0)-T1-AT's TC is measured and binned during final test to ensure consistency across production lots.
