Product details
Overview
RD36F(N6)-AZ from Renesas Electronics is a 1 W planar-type silicon Zener diode with nominal zener voltage of 36 V (B3 grade: 35.19–37.01 V), dynamic impedance ≤20 Ω at 10 mA, and zener voltage temperature coefficient of +27 mV/°C (typical). It features DO-41 glass-sealed DHD (Double Heatsink Diode) packaging and is used in precision voltage regulation and surge absorption circuits for industrial power supplies.
For engineers reviewing the RD36F(N6)-AZ datasheet, RD36F(N6)-AZ pinout, RD36F(N6)-AZ application, or RD36F(N6)-AZ equivalent, this device serves as a stable, low-impedance voltage reference in constant-voltage and overvoltage protection designs where ±5% tolerance, thermal stability, and 400 W surge capability (t = 10 μs) are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled voltage tolerance via B3-grade binning (35.19–37.01 V at IZ = 10 mA). Its planar junction structure ensures consistent dynamic impedance (ZZ ≤ 20 Ω) and low leakage (IR ≤ 10 μA at VR = 28.8 V).
The device uses a DO-41 package with axial leads and black cathode marking, enabling standard through-hole mounting. Thermal resistance is optimized via the DHD structure, supporting 1 W continuous dissipation at TA ≤ 50°C and 400 W non-repetitive surge power at t = 10 μs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 35.19–37.01 V at IZ = 10 mA - defines precise clamping threshold for overvoltage protection |
| Power Dissipation (P) | 1.0 W continuous - supports stable operation in compact PCB layouts without forced cooling |
| Dynamic Impedance (ZZ) | ≤20 Ω at IZ = 10 mA - ensures minimal voltage deviation under load transients |
| Reverse Current (IR) | ≤10 μA at VR = 28.8 V - guarantees low standby leakage in battery-backed systems |
| Zener Tempco (γZ) | +27 mV/°C (typical) - enables predictable drift compensation in temperature-sensitive references |
| Surge Power (PRSM) | 400 W at t = 10 μs - absorbs transient spikes without failure in input-stage protection |
| Junction Temperature (Tj) | 175°C maximum - allows reliable operation in high-ambient industrial environments |
Pinout & Package
RD36F(N6)-AZ uses a DO-41 axial-leaded glass package (JEDEC standard), with cathode identified by a black band. The device has two terminals: anode and cathode - no internal circuitry or multi-pin configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node in shunt regulator | Connected to system ground or lower-potential rail; carries forward current up to 200 mA |
| Cathode | Zener breakdown terminal / Voltage clamp output | Connected to regulated node; maintains 36 V reference under reverse bias and absorbs surge energy |
Key Features
| Feature | Design Value |
|---|---|
| Wide zener voltage range (2–82 V) with E24 series grading | Enables standardized BOM consolidation across multiple voltage rails in industrial power designs |
| B3-grade voltage binning (±2.5% tolerance) | Delivers tighter regulation than general-purpose Zeners for feedback loop stability in SMPS |
| DO-41 glass package with DHD thermal structure | Provides superior heat dissipation vs. plastic packages-critical for 1 W continuous operation |
| 400 W surge rating (10 μs pulse) | Eliminates need for external TVS in cost-sensitive input protection stages |
| −65 to +175°C storage and operating temperature range | Supports deployment in uncontrolled ambient environments such as factory-floor controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4738A (ON Semiconductor) | 33 V nominal, ±5% tolerance, ZZ = 35 Ω @ 76 mA, DO-41 package | Lower voltage and higher ZZ limit use in high-precision feedback loops | Select when 33 V clamping suffices and cost is prioritized over regulation tightness |
| BZX85C36 (Nexperia) | 36 V nominal, ±5% tolerance, ZZ = 50 Ω @ 5 mA, DO-41 package | Higher dynamic impedance reduces transient response fidelity in fast-switching protection | Prefer for general-purpose voltage referencing where 1 W derating margin is acceptable |
Compared with RD36F(N6)-AZ, the 1N4738A offers lower cost but sacrifices 3 V headroom and regulation accuracy; the BZX85C36 matches voltage but delivers inferior dynamic performance and thermal robustness-making RD36F(N6)-AZ optimal for industrial-grade 36 V reference and surge suppression where stability and surge resilience are design-critical.

FAQ
What is the exact zener voltage range for RD36F(N6)-AZ?
The RD36F(N6)-AZ is specified as a B3-grade device with a zener voltage range of 35.19 V to 37.01 V at test current IZ = 10 mA, per Renesas datasheet D13936EJ5V0DS. This ±2.5% tolerance ensures consistent clamping behavior in production units without post-manufacturing sorting.
Does RD36F(N6)-AZ have a defined cathode marking?
Yes, RD36F(N6)-AZ uses a black band on the glass body to indicate the cathode terminal, consistent with JEDEC DO-41 standards. This marking is visible under standard visual inspection and aligns with Renesas' package drawing in datasheet D13936EJ5V0DS.
What is the maximum surge power rating for RD36F(N6)-AZ?
RD36F(N6)-AZ supports a non-repetitive surge reverse power of 400 W at pulse width t = 10 μs, as confirmed in Figure 7 of the official Renesas datasheet D13936EJ5V0DS. This rating applies at TA = 25°C and is validated for single-event transient suppression.
Is RD36F(N6)-AZ suitable for automotive applications?
RD36F(N6)-AZ is classified as a "Standard" quality grade device per Renesas documentation, intended for industrial, office, and consumer equipment-not automotive or safety-critical systems. It lacks AEC-Q200 qualification and is not recommended for vehicle ECUs or ADAS subsystems.
What is the thermal resistance characteristic of RD36F(N6)-AZ?
RD36F(N6)-AZ exhibits a typical thermal resistance (Rth) of ~150°C/W (junction-to-ambient) at S = 5 mm² copper area, per Figure 2 in datasheet D13936EJ5V0DS. Derating is required above TA = 50°C to maintain 1 W continuous power dissipation within safe junction limits.
