Product details
Overview
RD36F(N6)-T6-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 temperature coefficient of +27 mV/°C, designed for precision voltage regulation and surge absorption in industrial power supply rails.
For engineers reviewing the RD36F(N6)-T6-AZ datasheet, RD36F(N6)-T6-AZ pinout, RD36F(N6)-T6-AZ application, or RD36F(N6)-T6-AZ equivalent, this device serves as a stable, glass-sealed, DO-41 packaged reference element in overvoltage protection, waveform clipping, and constant-current biasing circuits where ±3% zener tolerance and low thermal drift are required.
Technical Context
This Zener diode employs a planar junction structure with Double Heatsink Diode (DHD) glass sealing to achieve reliable thermal dissipation and stable reverse breakdown behavior. Its B3 voltage grade ensures tight 35.19–37.01 V tolerance at 10 mA test current, and its positive temperature coefficient (+27 mV/°C) supports temperature-compensated reference designs when paired with negative-coefficient devices.
The RD36F(N6)-T6-AZ operates within a −65°C to +175°C storage range and supports surge reverse power up to 400 W for 10 μs pulses. Its 1 W steady-state power rating is derated linearly above 25°C ambient per the published P vs. TA curve, with thermal resistance dependent on PCB copper area.
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 |
| Dynamic Impedance (ZZ) | ≤20 Ω at IZ = 10 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (P) | 1.0 W at TA = 25°C - sets maximum continuous DC power handling before thermal derating |
| Zener Temp. Coefficient (γZ) | +27 mV/°C - enables predictable voltage drift compensation in temperature-stable references |
| Reverse Current (IR) | ≤10 μA at VR = 27 V - guarantees low leakage in high-impedance bias networks |
| Surge Reverse Power (PRSM) | 400 W (t = 10 μs) - supports transient suppression of short-duration ESD or inductive spikes |
| Junction Temperature (Tj) | 175°C max - determines safe operating margin under sustained power stress |
Pinout & Package
RD36F(N6)-T6-AZ uses the JEDEC DO-41 axial-leaded glass package (3.0 mm diameter × 5.0 mm length), with cathode indicated 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 | Connected to lower-potential node in reverse-bias regulation; carries forward current up to 200 mA |
| Cathode | Zener breakdown terminal | Marked with black band; connected to higher-potential node during regulation; defines clamping polarity |
Key Features
| Feature | Design Value |
|---|---|
| Planar junction with DHD glass seal | Enables 1 W continuous power handling and robust mechanical integrity in industrial environments |
| B3-grade voltage tolerance | ±2.5% (35.19–37.01 V) at 10 mA - reduces binning overhead in precision reference designs |
| Positive temperature coefficient | +27 mV/°C - allows series combination with negative-TC devices for near-zero-drift references |
| Low dynamic impedance | ≤20 Ω at 10 mA - maintains regulation accuracy under varying load currents |
| High surge power capability | 400 W for 10 μs - absorbs fast transients without degradation in power supply input stages |
Applications
| Industrial Power Supply Regulation | ESD-Protected Signal Clamping |

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 = 25 Ω, DO-41, RoHS-compliant | Lower voltage grade; wider tolerance; higher ZZ limits precision use | Select when 33 V clamping suffices and cost sensitivity outweighs tight regulation needs |
| BZX85C36 (Nexperia) | 36 V nominal, ±5% tolerance, ZZ = 30 Ω, DO-41, 1.3 W rating | Same nominal voltage but looser tolerance and higher ZZ; higher P rating offers marginal thermal headroom | Prefer for non-critical 36 V references where extended power margin is prioritized over regulation accuracy |
Compared with RD36F(N6)-T6-AZ, the 1N4738A provides lower voltage and reduced precision, while the BZX85C36 matches nominal voltage but trades tighter tolerance and lower dynamic impedance for higher power rating-making RD36F(N6)-T6-AZ optimal for applications demanding ±2.5% accuracy and sub-20 Ω regulation stiffness.

FAQ
What is the exact zener voltage range for RD36F(N6)-T6-AZ at 10 mA test current?
The RD36F(N6)-T6-AZ has a guaranteed zener voltage range of 35.19 V to 37.01 V when tested at IZ = 10 mA, corresponding to its B3 grade classification per Renesas datasheet D13936EJ5V0DS. This ±2.5% tolerance ensures consistent clamping performance across production units without additional sorting.
Does RD36F(N6)-T6-AZ support surge protection per IEC 61000-4-5?
Yes, RD36F(N6)-T6-AZ supports surge absorption with a rated surge reverse power of 400 W for 10 μs pulses (per Figure 7 in datasheet D13936EJ5V0DS), making it suitable for primary-level protection in IEC 61000-4-5 Level 3 (1 kV/2 kV) applications when properly coordinated with series impedance.
What is the maximum allowable junction temperature for RD36F(N6)-T6-AZ?
The maximum junction temperature (Tj) for RD36F(N6)-T6-AZ is 175°C, as specified in the Absolute Maximum Ratings table of Renesas datasheet D13936EJ5V0DS. Operation beyond this limit risks irreversible parametric shift or catastrophic failure.
Is RD36F(N6)-T6-AZ RoHS compliant?
RD36F(N6)-T6-AZ is manufactured to meet RoHS Directive requirements, as confirmed by Renesas Electronics' environmental compliance documentation referenced in datasheet D13936EJ5V0DS and supported by material declarations for legacy DO-41 Zener diodes in the RDx.xF series.
How does the +27 mV/°C temperature coefficient of RD36F(N6)-T6-AZ affect circuit stability?
The +27 mV/°C zener voltage temperature coefficient of RD36F(N6)-T6-AZ causes output voltage to increase predictably with temperature-enabling intentional compensation when combined with negative-TC components (e.g., forward-biased diodes) to achieve near-zero net drift in precision reference designs.
