Product details
Overview
RD5.6S-T1-AT from Renesas Electronics is a 200 mW, 2-pin Super Mini Mold surface-mount Zener diode with a nominal zener voltage of 5.6 V (5.29–5.94 V range at 5 mA), dynamic impedance ≤80 Ω, and reverse current ≤5 μA at 2.5 V. It serves as a precision voltage reference or clamp in low-power analog signal conditioning, power supply feedback loops, and overvoltage protection circuits.
For engineers reviewing the RD5.6S-T1-AT datasheet, RD5.6S-T1-AT pinout, RD5.6S-T1-AT application, or RD5.6S-T1-AT equivalent, this page delivers verified electrical specs, package dimensions, thermal behavior, real-world use cases, and validated alternative parts - all confirmed against Renesas' official D11444EJ6V0DS datasheet (6th edition, August 2006).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage regulation under controlled current conditions. Its sharp breakdown characteristic and E24-standardized VZ tolerance support repeatable circuit design across production batches.
Designed for surface-mount assembly on standard PCBs, RD5.6S-T1-AT features a glass-passivated chip in a lead-free, RoHS-compliant Super Mini Mold package (2.5 × 1.25 mm footprint) with cathode marking. Thermal resistance is 625°C/W (PCB-mounted, 30×30×1.6 mm glass epoxy).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.29–5.94 V at IZ = 5 mA - defines regulated output voltage window under nominal bias |
| Dynamic Impedance (ZZ) | ≤80 Ω at IZ = 5 mA - determines voltage stability under small-signal load variations |
| Reverse Current (IR) | ≤5 μA at VR = 2.5 V - ensures low leakage in standby or high-impedance sensing nodes |
| Power Dissipation (P) | 200 mW at TA = 25°C - sets maximum continuous DC power handling on standard PCB |
| Surge Power (PRSM) | 85 W at t = 10 μs (single pulse) - supports transient overvoltage clamping without failure |
| Junction Temperature (Tj) | −55 to +150°C - enables operation in industrial ambient environments with proper derating |
Pinout & Package
RD5.6S-T1-AT uses a 2-pin Super Mini Mold package (2.5 ±0.15 mm × 1.25 ±0.1 mm × 0.9 ±0.1 mm height) with cathode indicated by a band on one end. No internal terminals beyond anode and cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / reference ground node | Connected to lower-potential side in reverse-bias configuration; establishes reference point for VZ |
| Cathode | Zener breakdown terminal / regulated output node | Marked with band; supplies stable voltage when reverse-biased above VZ threshold |
Key Features
| Feature | Design Value |
|---|---|
| Sharp breakdown characteristic | Enables precise voltage clamping with minimal knee voltage spread - critical for tight-tolerance references |
| E24-standardized VZ | Guarantees consistent binning across production lots - simplifies BOM management and calibration |
| 200 mW rated power | Supports direct integration into low-current feedback paths without external heat sinking |
| Lead-free & RoHS-compliant | Meets global environmental compliance requirements for commercial and industrial PCB assembly |
Applications
| Power Supply Feedback | Signal Level Clamping |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck converter feedback networks using optocoupler-coupled error amplifiers. IC Role / Device Role / Timing Role: Provides stable 5.6 V reference to TL431-like shunt regulator ICs or discrete op-amp comparators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F (Diodes Inc.) | Same 5.6 V nominal VZ, but 350 mW rating and SOT-323 package (2.2 × 1.35 mm); ZZ = 17 Ω max at 20 mA | Higher power and lower impedance suit higher-current references; larger footprint may require layout change | Select when >10 mA bias current or tighter regulation is required; verify thermal margin on target PCB |
| BZX384-B5V6 (Nexperia) | 5.6 V VZ (5.46–5.74 V), 300 mW, SOD-323 package (1.7 × 1.25 mm); ZZ = 40 Ω max at 5 mA | Smaller footprint matches RD5.6S-T1-AT's 1.25 mm width but shorter length (1.7 mm vs. 2.5 mm); tighter VZ tolerance | Preferred for space-constrained designs needing improved VZ consistency; confirm solder profile compatibility |
Compared with RD5.6S-T1-AT, MMBZ5232BS-7-F offers higher power and lower impedance at increased size, while BZX384-B5V6 provides tighter VZ tolerance in a smaller footprint - both require validation of thermal performance and PCB layout adaptation.

FAQ
What is the zener voltage tolerance of RD5.6S-T1-AT?
The RD5.6S-T1-AT has a zener voltage range of 5.29 V to 5.94 V at 5 mA test current, corresponding to a ±5.6% tolerance about the nominal 5.6 V value. This range is defined per Class B specification in the Renesas D11444EJ6V0DS datasheet and applies across the full operating temperature range when derated per thermal curves.
Can RD5.6S-T1-AT be used in automotive applications?
No - RD5.6S-T1-AT is rated for "Standard" quality grade per Renesas documentation, intended for computers, office equipment, and industrial robots. It is not qualified for automotive use (which requires "High Quality" grade), lacks AEC-Q200 stress testing, and has no guaranteed PPAP or zero-defect manufacturing support.
What is the maximum reverse surge power rating for RD5.6S-T1-AT?
RD5.6S-T1-AT supports a non-repetitive reverse surge power of 85 W at a pulse width of 10 μs, as specified in Figure 12 of the D11444EJ6V0DS datasheet. This rating assumes single-event transients; repeated surges must respect average power limits and thermal time constants shown in Figure 11.
Does RD5.6S-T1-AT have a specified temperature coefficient?
Yes - RD5.6S-T1-AT exhibits a positive temperature coefficient typical of mid-voltage Zeners. While the exact mV/°C value is not tabulated individually, Figure 9 in the datasheet places it near +2.5 mV/°C (≈+0.045%/°C) based on its 5.6 V position within the RD2.0S–RD39S curve family.
Is RD5.6S-T1-AT compatible with lead-free reflow soldering?
Yes - RD5.6S-T1-AT is RoHS-compliant and qualified for lead-free reflow per J-STD-020. Its glass-passivated chip and Super Mini Mold package withstand peak temperatures up to 260°C for 10 seconds. Recommended profile follows IPC/JEDEC J-STD-020D with ramp rates ≤3°C/s and time above liquidus ≤60 s.
