Product details
Overview
RD10E(N)-T2 from NEC Corporation is a silicon epitaxial planar Zener diode with 10 V nominal breakdown voltage, 5% tolerance, 500 mW power dissipation, and SC-76 (SSP) surface-mount package; used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the RD10E(N)-T2 datasheet, RD10E(N)-T2 pinout, RD10E(N)-T2 application, or RD10E(N)-T2 equivalent, key selection criteria include Zener voltage accuracy, temperature coefficient, dynamic impedance, maximum reverse leakage current, and taping orientation (-T2 denotes tape-and-reel feed direction per NEC SC-76 specification).
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a specified test current of 5 mA, exhibits a typical temperature coefficient of ±0.05 %/°C near 10 V, and maintains stable regulation under load variations within its 500 mW thermal limit.
The SC-76 (SSP) package provides a compact 1.6 × 1.6 × 0.55 mm outline with single-terminal cathode marking and anode connection via the die attach pad; -T2 taping specifies component orientation for automated placement with cathode toward sprocket hole side.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10 V ±5% at IZ = 5 mA - defines stable reference point for biasing or clamping |
| Power Dissipation (PD) | 500 mW - sets maximum continuous reverse power before thermal derating |
| Dynamic Impedance (ZZT) | 15 Ω max at IZ = 5 mA - determines output voltage stability under current variation |
| Reverse Leakage (IR) | 1 μA max at VR = 7.5 V - ensures minimal quiescent current in standby regulation |
| Temperature Coefficient | ±0.05 %/°C - enables predictable VZ drift across -55°C to +150°C operating range |
| Taping Format | -T2 orientation per NEC SC-76 spec - ensures correct rotational alignment during SMT pick-and-place |
Pinout & Package
SC-76 (SSP) is a 2-terminal surface-mount package with cathode marked by a band on the top surface; anode connects to the exposed metal pad underneath.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked end) | Reverse-bias terminal | Connected to regulated node; voltage referenced to this point during Zener operation |
| Anode (unmarked end / pad) | Reference/ground terminal | Typically tied to circuit ground or lower potential; forms current return path |
Key Features
| Feature | Design Value |
|---|---|
| Precision 10 V regulation | ±5% tolerance enables use in 3.3 V and 5 V system reference scaling without trimming |
| Low dynamic impedance | 15 Ω max improves load regulation error to <15 mV per 1 mA load change |
| SC-76 (SSP) footprint | 1.6 × 1.6 mm area supports high-density PCB layouts in space-constrained modules |
| -T2 taping compliance | Guarantees consistent orientation for automated assembly with standard 8 mm carrier tape feeders |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A-TAP | 10 V ±5%, 1 W rating, DO-41 through-hole package | Requires PCB through-hole mounting and manual rework; higher thermal mass limits response speed | Choose when board-level repairability or higher pulse power handling is required |
| BZX55C10-TR | 10 V ±5%, 500 mW, DO-35 glass package with axial leads | Larger footprint and lead-forming needed; not compatible with fine-pitch SMT assembly | Prefer for prototyping or legacy designs where SC-76 footprint is unavailable |
Compared with RD10E(N)-T2, the 1N4740A-TAP offers higher power but lacks SMT compatibility, while BZX55C10-TR matches power and voltage but requires leaded assembly-RD10E(N)-T2 uniquely combines SC-76 miniaturization, -T2 taping, and industrial-grade reliability in a single solution.

FAQ
What is the Zener voltage tolerance of RD10E(N)-T2?
The RD10E(N)-T2 has a Zener voltage tolerance of ±5% at 5 mA test current, meaning its actual breakdown voltage falls between 9.5 V and 10.5 V under standard operating conditions. This tolerance is guaranteed across the full industrial temperature range and is verified during final electrical test. The RD10E(N)-T2 maintains this specification without external calibration or trimming.
Does RD10E(N)-T2 support automated SMT assembly?
Yes, RD10E(N)-T2 supports automated SMT assembly via its SC-76 (SSP) package and -T2 taping configuration, which complies with JEDEC standards for 8 mm carrier tape orientation. The -T2 designation specifies cathode-first placement direction, ensuring consistent rotation during pick-and-place. RD10E(N)-T2 is qualified for reflow profiles up to 260°C peak temperature per J-STD-020.
What is the maximum reverse leakage current for RD10E(N)-T2?
The maximum reverse leakage current for RD10E(N)-T2 is 1 μA at 7.5 V reverse voltage and 25°C ambient temperature. This value increases to ≤5 μA at 125°C, remaining well within design margins for low-power reference and clamp applications. RD10E(N)-T2's low IR ensures minimal loading on high-impedance nodes in sensor front-ends and supervisor circuits.
Can RD10E(N)-T2 be used as a voltage reference in precision ADC circuits?
RD10E(N)-T2 can serve as a cost-effective voltage reference in medium-precision ADC circuits where ±0.5% full-scale accuracy is acceptable. Its 10 V output, ±5% tolerance, and ±0.05 %/°C temperature coefficient allow stable scaling of 3.3 V or 5 V inputs. For higher precision, external trimming or buffering is recommended; RD10E(N)-T2 itself does not include internal compensation or buffered output.
Is RD10E(N)-T2 RoHS compliant?
RD10E(N)-T2 was manufactured prior to RoHS enforcement and does not carry formal RoHS certification. It contains lead in solder and chip metallization per pre-2006 NEC process standards. For new designs requiring RoHS compliance, consider modern equivalents such as the BZX84-C10LT1G or MMBZ5240BLT1G, which maintain similar electrical specs while meeting EU directive requirements. RD10E(N)-T2 remains available for legacy repair and obsolescence-mitigation programs.
