Product details
Overview
RD6.2E(N)-T2 from NEC Corporation is a 6.2 V Zener diode in SC-76 (SSP) surface-mount package, rated for 500 mW power dissipation, with ±5% tolerance and 100 µA maximum reverse leakage at rated voltage, used for precision voltage regulation and overvoltage protection in low-power analog circuits.
For engineers reviewing the RD6.2E(N)-T2 datasheet, RD6.2E(N)-T2 pinout, RD6.2E(N)-T2 application, or RD6.2E(N)-T2 equivalent, key selection criteria include Zener voltage accuracy, power rating under pulsed vs. DC conditions, thermal resistance in SC-76 footprint, and compatibility with automated SMT placement for high-reliability consumer and industrial PCBs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage across its terminals. It exhibits a nominal Zener voltage of 6.2 V with tight ±5% tolerance and specified test current of 5 mA, ensuring predictable clamping behavior in biasing and protection circuits.
Designed for surface-mount assembly, the RD6.2E(N)-T2 uses SC-76 (SSP) packaging with standardized tape-and-reel orientation (-T2 variant), supporting automated pick-and-place handling at 3000 units per reel. Its junction-to-air thermal resistance is typical 450 °C/W, limiting continuous DC power dissipation to 500 mW at 25 °C ambient.
Key Specifications

| Power Dissipation (PZ) | 500 mW max at TA = 25 °C - sets absolute DC operating limit without heatsinking |
| Reverse Leakage (IR) | ≤100 µA at VR = 4.0 V - ensures minimal quiescent current in standby bias networks |
| Zener Impedance (ZZT) | Typ. 40 Ω at IZ = 5 mA - determines AC regulation stiffness under dynamic load changes |
| Package | SC-76 (SSP) - 2-pin, 1.6 × 1.2 × 0.6 mm outline compatible with JEDEC MO-203AA |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C6V2 | Same 6.2 V ±5%, but SOD-323 package (1.7 × 1.3 mm); 300 mW rating | Limited to lower-power clamping due to reduced PZ; less thermal margin in dense layouts | Choose BZX584-C6V2 only if board space is constrained and peak pulse energy remains <10 mJ |
| MMSZ4688 | 6.2 V ±5%, SOD-123 package; 500 mW rating but higher ZZT (70 Ω typ.) | Higher impedance causes greater reference shift under load variation | Select MMSZ4688 only when cost is prioritized over regulation stiffness in non-critical bias networks |
Compared with BZX584-C6V2 and MMSZ4688, the RD6.2E(N)-T2 delivers identical voltage accuracy with superior thermal capability in a slightly smaller footprint, making it optimal for space-constrained yet thermally demanding 500 mW Zener applications requiring stable DC regulation.

FAQ
What is the Zener voltage tolerance for RD6.2E(N)-T2?
The RD6.2E(N)-T2 has a Zener voltage tolerance of ±5% at 6.2 V, measured under standard test conditions of 5 mA Zener current and 25 °C ambient temperature. This tolerance is guaranteed across the full operating temperature range and applies to every unit shipped, enabling direct use in precision biasing without binning or calibration.
Does RD6.2E(N)-T2 support automated SMT placement?
Yes, RD6.2E(N)-T2 is supplied in -T2 taping format on 3000-unit reels conforming to SC-76 (SSP) orientation standards. The -T2 designation specifies anode-first tape direction, ensuring consistent pickup and placement alignment in high-speed pick-and-place machines without manual orientation verification.
What is the maximum reverse leakage current for RD6.2E(N)-T2?
The RD6.2E(N)-T2 specifies a maximum reverse leakage current of 100 µA at 4.0 V reverse voltage and 25 °C. This value is verified per unit during final test and ensures minimal loading on high-impedance nodes such as op-amp bias dividers or sensor signal conditioning paths.
Can RD6.2E(N)-T2 be used in place of RD6.2S-T1?
No - RD6.2E(N)-T2 and RD6.2S-T1 differ in both Zener voltage tolerance (±5% vs. ±10%) and taping orientation (-T2 vs. -T1). The RD6.2E(N)-T2 offers tighter regulation but requires revalidation of tape feed settings and may not be interchangeable without process adjustment.
What thermal derating applies to RD6.2E(N)-T2 above 25 °C ambient?
The RD6.2E(N)-T2 must be derated linearly above 25 °C ambient at 4.0 mW/°C, based on its specified thermal resistance. At 75 °C ambient, its usable power dissipation drops to 300 mW. This derating curve is defined in NEC's original SC-76 Zener datasheet and applies regardless of PCB copper area or airflow.
