Product details
Overview
RD11SL(0)-T1-AT from Renesas Electronics is a 2-pin Super Mini Mold zener diode with nominal zener voltage 10.32–11.50 V, 200 mW power dissipation, 60 Ω dynamic impedance at 0.5 mA, and low-noise sharp breakdown characteristic - used for precision voltage reference and waveform clipping in audio and instrumentation circuits.
For engineers reviewing the RD11SL(0)-T1-AT datasheet, RD11SL(0)-T1-AT pinout, RD11SL(0)-T1-AT application, or RD11SL(0)-T1-AT equivalent, key selection criteria include zener voltage tolerance (±5% Class N), reverse current limit (0.1 µA at 8.0 V), thermal resistance (625°C/W on 30×30×1.6 mm PCB), and compliance with E24 standard voltage grading.
Technical Context
This device operates as a two-terminal voltage-reference element relying on controlled avalanche breakdown in silicon PN junction. Its sharp knee and low noise stem from optimized doping profile and Super Mini Mold packaging, enabling stable regulation under low-current bias (0.5 mA test condition).
Designed for ambient temperatures from –55°C to +150°C, it exhibits a positive zener voltage temperature coefficient (~+7.5 mV/°C near 11 V) and supports non-repetitive surge reverse power up to 2.2 W for 10 µs pulses - critical for transient suppression in analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (Vz) | 10.32–11.50 V at 0.5 mA - defines regulated output range for constant-voltage circuits |
| Power Dissipation (P) | 200 mW at TA = 25°C - sets maximum continuous DC power handling on standard PCB |
| Dynamic Impedance (Zz) | 60 Ω max at Iz = 0.5 mA - determines regulation stiffness and AC ripple rejection |
| Reverse Current (IR) | 0.1 µA max at VR = 8.0 V - ensures minimal leakage in high-impedance bias networks |
| Junction Temperature (Tj) | 150°C max - constrains thermal design margin for reliability in sealed enclosures |
| Surge Power (PRSM) | 2.2 W for 10 µs pulse - enables transient overvoltage clamping without degradation |
Pinout & Package
RD11SL(0)-T1-AT uses a 2-pin Super Mini Mold package (SOD-323 equivalent footprint), with cathode indicated by band marking. Dimensions: 2.5±0.15 mm length × 1.25±0.1 mm width × 0.9±0.1 mm height; lead pitch 1.7±0.1 mm; cathode terminal is Pin 2.

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 Vz, but 500 mW rating and DO-35 package - larger footprint and higher power capability | Suitable for higher-power regulation where board space allows; not drop-in due to package mismatch | Select when >200 mW dissipation or legacy through-hole assembly required |
| MMSZ4686 (Vishay) | 10 V Vz, SOD-123 package, 500 mW rating, 150 Ω Zz - higher impedance and different thermal profile | Better suited for general-purpose clamping than precision reference; less stable at low currents | Prefer for cost-sensitive surge protection where tight Vz tolerance is secondary |
Compared with BZX55C10 and MMSZ4686, RD11SL(0)-T1-AT offers tighter Vz tolerance (±5%), lower Zz (60 Ω), and smaller SOD-323-compatible footprint - making it optimal for space-constrained, low-noise analog references where 200 mW suffices.

FAQ
What is the zener voltage range for RD11SL(0)-T1-AT?
The RD11SL(0)-T1-AT has a specified zener voltage range of 10.32 V to 11.50 V at test current Iz = 0.5 mA, corresponding to Class N tolerance per the datasheet. This range reflects manufacturing variation within the E24 standard and ensures predictable regulation behavior in precision analog circuits where RD11SL(0)-T1-AT is deployed.
Is RD11SL(0)-T1-AT RoHS compliant?
Yes, RD11SL(0)-T1-AT meets EU RoHS Directive requirements as confirmed by Renesas Electronics' environmental compliance documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is suitable for use in consumer and industrial electronics where RoHS adherence is mandatory for RD11SL(0)-T1-AT deployment.
What is the maximum allowable reverse current for RD11SL(0)-T1-AT at 8.0 V?
At VR = 8.0 V, the RD11SL(0)-T1-AT exhibits a maximum reverse current (IR) of 0.1 µA, as specified in the Electrical Characteristics table. This ultra-low leakage supports high-impedance bias networks and precision reference designs where current draw must be minimized - a key performance attribute distinguishing RD11SL(0)-T1-AT from higher-leakage alternatives.
Can RD11SL(0)-T1-AT be used in surface-mount reflow processes?
Yes, RD11SL(0)-T1-AT is qualified for standard SMD reflow soldering per J-STD-020 guidelines. Its Super Mini Mold package withstands peak temperatures up to 260°C for 10 seconds. Thermal profiles must respect its 150°C maximum junction temperature, and board layout should ensure adequate copper area for heat dissipation during RD11SL(0)-T1-AT operation.
What is the thermal resistance (θJA) of RD11SL(0)-T1-AT on a standard PCB?
The RD11SL(0)-T1-AT has a junction-to-ambient thermal resistance (θJA) of 625°C/W when mounted on a 30 mm × 30 mm × 1.6 mm glass-epoxy PCB - as shown in Figure 7 of the datasheet. This value directly determines safe power derating: at 75°C ambient, max continuous power drops to ~120 mW, a critical constraint for reliable RD11SL(0)-T1-AT implementation.
