Product details
Overview
RD62E(N)-T4 is a 6.2 V Zener diode from NEC Corporation in SC-76 (SSP) surface-mount package, with 5% tolerance, 500 mW power dissipation, and 100 µA maximum reverse leakage at rated voltage, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the RD62E(N)-T4 datasheet, RD62E(N)-T4 pinout, RD62E(N)-T4 application, or RD62E(N)-T4 equivalent, key selection factors include Zener voltage accuracy, thermal stability under bias, package thermal resistance, and taping configuration compatibility with automated placement systems.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under specified current conditions. It is characterized by a nominal Zener voltage of 6.2 V at test current IZT = 5 mA, with dynamic impedance of 50 Ω typical and temperature coefficient of +2.5 mV/°C.
The SC-76 (SSP) package provides compact footprint (1.6 × 0.8 mm) and low thermal resistance (500 °C/W junction-to-air), enabling reliable operation in space-constrained PCB layouts without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.2 V ±5% at IZT = 5 mA - defines stable regulation point for reference or clamp circuits |
| Power Dissipation (PZM) | 500 mW - sets maximum continuous DC power handling at TA = 25°C |
| Reverse Leakage (IR) | ≤100 µA at VR = 4.0 V - ensures low standby current in voltage-sensing paths |
| Zener Impedance (ZZT) | 50 Ω typical at IZT = 5 mA - determines regulation sensitivity to load current changes |
| Temperature Coefficient | +2.5 mV/°C - quantifies drift rate of VZ over operating temperature range |
| Package | SC-76 (SSP) - 2-terminal SMD package with 1.6 × 0.8 mm footprint and gull-wing leads |
Pinout & Package
SC-76 (SSP) is a 2-terminal surface-mount package with anode and cathode leads formed as gull-wing extensions. The device has no internal die bonding variation between RD62E(N)-T4 and other RD62x variants in this series.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower potential in Zener operation | Must be held at ≤(VZ − 0.7 V) relative to cathode to avoid forward conduction during regulation |
| Cathode | Current exit terminal in forward bias; connected to higher potential in Zener operation | Serves as regulated output node; polarity marking aligns with cathode band on package body |
Key Features
| Feature | Design Value |
|---|---|
| Precision Zener voltage tolerance | ±5% - enables use in 1%–2% accuracy analog references without trimming |
| Low dynamic impedance | 50 Ω typical - minimizes output voltage deviation under ±1 mA load current variation |
| Stable temperature coefficient | +2.5 mV/°C - supports predictable drift compensation in industrial temperature ranges |
| SC-76 (SSP) taping compliance | -T4 configuration - compatible with standard 8 mm tape-and-reel feeders for high-speed SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4687-TP (Micro Commercial) | 6.2 V ±5%, 500 mW, SC-70 package (2.2 × 1.35 mm) | Larger footprint; 100 °C/W higher junction-to-air thermal resistance | Preferred where board space allows larger package and thermal margin is less constrained |
| BZX84-C6V2 (ON Semiconductor) | 6.2 V ±5%, 350 mW, SOT-23 package | Lower power rating; 150 mW less dissipation capacity at 25°C | Selected when cost sensitivity outweighs need for full 500 mW headroom in low-duty-cycle clamping |
Compared with RD62E(N)-T4, MMSZ4687-TP offers identical electrical specs but requires PCB layout revision due to SC-70 size, while BZX84-C6V2 trades 150 mW power capability for broader distributor availability and lower unit cost in high-volume production.

FAQ
What is the Zener test current for RD62E(N)-T4?
The RD62E(N)-T4 is specified at a Zener test current IZT of 5 mA, which is the standardized condition used to measure its nominal 6.2 V Zener voltage and dynamic impedance. This current level ensures stable breakdown behavior while remaining within safe power limits for the 500 mW rating of the RD62E(N)-T4.
Does RD62E(N)-T4 have a defined cathode marking?
Yes, RD62E(N)-T4 uses a cathode band marking on the SC-76 (SSP) package body, consistent with JEDEC MO-203 standard orientation. The band identifies the cathode terminal, which must be connected to the higher-potential node in Zener regulation mode to ensure proper reverse-bias operation of the RD62E(N)-T4.
What is the maximum reverse leakage current for RD62E(N)-T4?
The RD62E(N)-T4 has a maximum reverse leakage current of 100 µA when measured at 4.0 V reverse bias, per its original NEC specification. This low leakage supports accurate voltage referencing in high-impedance analog circuits and minimizes quiescent current draw in battery-powered applications using the RD62E(N)-T4.
Is RD62E(N)-T4 compatible with lead-free reflow profiles?
Yes, RD62E(N)-T4's SC-76 (SSP) package and internal construction are compatible with standard lead-free reflow profiles (J-STD-020, peak 260°C). The device's glass-passivated junction and metallization system withstand repeated thermal cycling without degradation, ensuring long-term reliability after soldering the RD62E(N)-T4 onto PCBs.
What does the "-T4" suffix indicate in RD62E(N)-T4?
The "-T4" suffix in RD62E(N)-T4 denotes the taping configuration per NEC's SC-76 (SSP) specification - specifically, orientation and reel packaging compliant with automated SMT placement equipment using 8 mm carrier tape. This distinguishes RD62E(N)-T4 from -T1 or -T2 variants and ensures correct feeding direction during assembly of the RD62E(N)-T4.
