Product details
Overview
RD10SL-T1-A from Renesas Electronics is a 2-pin Super Mini Mold zener diode with a nominal zener voltage of 10.0 V (N3 class), 200 mW power dissipation, 60 Ω dynamic impedance at 0.5 mA test current, and 0.1 µA reverse current at 7.0 V. It delivers sharp breakdown and low-noise regulation for precision voltage reference and waveform clipping in audio and instrumentation circuits.
For engineers reviewing the RD10SL-T1-A datasheet, RD10SL-T1-A pinout, RD10SL-T1-A application, or RD10SL-T1-A equivalent, this page provides verified electrical parameters, package dimensions, thermal behavior, zener voltage tolerance bands (N/N1/N2/N3), and direct alternative options for constant-voltage and surge-absorption designs.
Technical Context
The RD10SL-T1-A operates as a two-terminal voltage-reference device relying on controlled reverse-biased avalanche breakdown. Its E24-standardized zener voltage (9.35–10.51 V) is specified across three tolerance classes (N1/N2/N3), with N3 covering 10.00–10.51 V at 0.5 mA. Dynamic impedance remains ≤60 Ω under rated test conditions.
Thermal performance is defined by a junction-to-ambient thermal resistance of 625°C/W on a 30×30×1.6 mm glass-epoxy PCB, and it supports non-repetitive surge reverse power up to 2.2 W for 10 µs pulses. The device exhibits a positive zener voltage temperature coefficient near +8.5 mV/°C at 10 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Vz) | 9.35–10.51 V (N class); N3 subclass = 10.00–10.51 V at 0.5 mA - defines stable regulation range for biasing or clamping |
| Power Dissipation (P) | 200 mW at TA = 25°C - sets maximum continuous DC power handling on standard PCB |
| Dynamic Impedance (Zz) | ≤60 Ω at Iz = 0.5 mA - ensures minimal output voltage variation under small-signal load changes |
| Reverse Current (IR) | ≤0.1 µA at VR = 7.0 V - guarantees high off-state blocking for low-leakage reference applications |
| Junction Temperature (Tj) | 150°C maximum - constrains thermal design margin when operating near Pmax |
| Surge Power (PRSM) | 2.2 W for t = 10 µs (non-repetitive) - enables transient overvoltage suppression without failure |
Pinout & Package
RD10SL-T1-A uses the 2-pin Super Mini Mold package (SOD-323 equivalent footprint), with cathode indicated by a band. Dimensions: 2.5±0.15 mm length, 1.25±0.1 mm width, 0.9±0.1 mm height, 0.3±0.05 mm lead pitch. Cathode terminal is electrically negative during zener operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to lower-potential node in zener mode | Must be held at least ~0.7 V below cathode to avoid forward conduction during regulation |
| Cathode | Negative terminal in forward bias; higher-potential node in zener regulation | Connected to supply rail or signal node requiring clamped/stabilized voltage |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener operation | Minimizes induced ripple in sensitive analog references and audio signal paths |
| Sharp breakdown characteristic | Enables clean, predictable turn-on for precision clamping and overvoltage detection |
| E24-standardized voltage grading | Ensures interchangeability within ±5% tolerance bands (N1/N2/N3) across production lots |
| Super Mini Mold package | Supports high-density PCB layouts with 0.3 mm lead pitch and <1 mm profile |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C10 (ON Semiconductor) | Same 10 V nominal, 500 mW rating, DO-35 package - larger footprint and higher Zz (up to 200 Ω) | Less suitable for space-constrained PCBs; better for higher-power dissipation needs | Select when board layout allows DO-35 and thermal budget exceeds 200 mW |
| MMSZ4686 (Diodes Inc.) | 10 V nominal, SOD-123 package, 500 mW, Zz ≤ 150 Ω - higher power but looser initial tolerance (±5%) | Higher surge capability but less precise regulation due to wider Vz spread | Choose when cost sensitivity outweighs need for N3-class tight tolerance |
Compared with BZX55C10 and MMSZ4686, RD10SL-T1-A offers superior voltage precision (N3: 10.00–10.51 V), lower dynamic impedance (≤60 Ω), and ultra-compact SOD-323-compatible packaging - making it optimal for high-density, low-noise, and tightly regulated reference designs.

FAQ
What is the exact zener voltage tolerance for RD10SL-T1-A?
The RD10SL-T1-A is specified in N3 class per the datasheet: minimum zener voltage is 10.00 V and maximum is 10.51 V at 0.5 mA test current. This 5.1% tolerance band is tighter than standard N-class (9.35–10.51 V) and supports precision regulation where tighter voltage control is required.
Does RD10SL-T1-A meet RoHS requirements?
Yes, RD10SL-T1-A complies with the EU RoHS Directive. Renesas Electronics confirms environmental compliance for this product family, including restriction of lead, mercury, cadmium, hexavalent chromium, PBB, and PBDE - as stated in official product documentation and distributor listings.
What is the maximum allowable reverse surge power for RD10SL-T1-A?
RD10SL-T1-A supports a non-repetitive surge reverse power of 2.2 W for pulse widths up to 10 µs, as shown in Figure 8 of the datasheet. This rating applies only to single, isolated transients - repeated surges require derating based on thermal time constants.
Can RD10SL-T1-A be used in place of RD10SL without the -T1-A suffix?
Yes, RD10SL-T1-A is the tape-and-reel packaged version of RD10SL, identical in electrical and mechanical specifications. The "-T1-A" denotes packaging format (10,000 pcs/reel, 8 mm tape), not functional differentiation - both share the same die, zener characteristics, and Super Mini Mold package.
What is the thermal resistance of RD10SL-T1-A on a standard PCB?
RD10SL-T1-A has a junction-to-ambient thermal resistance (RθJA) of 625°C/W when mounted on a 30 mm × 30 mm × 1.6 mm glass-epoxy PCB. This value assumes no additional copper pour or heatsinking - actual thermal performance improves with enhanced board layout.
