Product details
Overview
RD13ES-T4-AZ from Renesas Electronics is a 13 V ±5% zener diode in DO-34 glass package with 400 mW power dissipation, DHD (Double Heatsink Diode) construction, and 0.5 µA reverse current at 10 V. It delivers stable voltage regulation for low-power reference and protection circuits in consumer and industrial electronics.
For engineers reviewing the RD13ES-T4-AZ datasheet, RD13ES-T4-AZ pinout, RD13ES-T4-AZ application, or RD13ES-T4-AZ equivalent, key selection criteria include zener voltage tolerance (±5%), dynamic impedance (≤25 Ω at 5 mA), knee impedance (≤110 Ω), thermal resistance (375°C/W junction-to-ambient), and surge capability (100 W, 10 µs).
Technical Context
This planar-processed zener diode uses Double Heatsink Diode (DHD) construction to enhance thermal performance in the compact DO-34 package. Its E24-standard zener voltage (13 V nominal) is specified at 5 mA test current with tight ±5% tolerance and low temperature coefficient (≈–0.04 %/°C).
The device operates within a junction temperature range of –65°C to +175°C and supports surge reverse power up to 100 W for 10 µs pulses. Reverse current remains ≤0.2 µA at VR = 10 V, ensuring minimal leakage in precision biasing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.18 V to 13.62 V at IZ = 5 mA - defines stable regulation window for 13 V reference designs |
| Power Dissipation (P) | 400 mW at TA = 25°C - sets maximum continuous DC power handling on standard PCB |
| Dynamic Impedance (ZZ) | ≤25 Ω at IZ = 5 mA - ensures low AC impedance for ripple suppression in analog references |
| Knee Dynamic Impedance (ZZK) | ≤110 Ω - maintains regulation integrity near knee current, critical for low-current bias networks |
| Reverse Current (IR) | ≤0.2 µA at VR = 10 V - guarantees negligible leakage in high-impedance voltage divider or sensor biasing |
| Surge Reverse Power (PRSM) | 100 W (t = 10 µs) - provides transient overvoltage clamping for ESD and line-surge protection |
| Junction Temperature (Tj) | –65°C to +175°C - enables operation in extended-temperature industrial environments |
Pinout & Package
RD13ES-T4-AZ is a two-terminal axial-leaded zener diode in JEDEC DO-34 glass package (body length ≤2.4 mm, diameter ≤2.0 mm). Cathode is marked by black band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / cathode-side reference node | Connected to lower-potential side in reverse-biased regulation; forms ground-referenced voltage clamp |
| Cathode | Zener breakdown terminal / regulated output node | Provides stable 13 V reference when reverse-biased; must be held at higher potential than anode |
Key Features
| Feature | Design Value |
|---|---|
| DHD (Double Heatsink Diode) construction | Enables 400 mW dissipation in DO-34 by improving heat transfer through both leads and glass body |
| DO-34 glass sealed package | Supports 5 mm PCB pitch insertion and offers hermetic reliability for long-term stability |
| E24-standard zener voltage | Ensures compatibility with industry-standard resistor and reference networks without custom calibration |
| Low knee impedance (≤110 Ω) | Maintains regulation down to sub-mA currents, enabling use in ultra-low-power sensor biasing |
| 100 W surge rating (10 µs) | Clamps fast transients without degradation-suitable for I/O line protection in non-automotive systems |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Providing stable 13 V reference for linear regulator feedback or ADC reference buffer in embedded power modules. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference node voltage.

Use Value: Low 0.2 µA leakage at 10 V ensures stable current setpoint even with high-value bias resistors (>1 MΩ). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V nominal, ±5%, 1 W power rating, DO-41 package | Higher power handling but larger footprint; less suitable for 5 mm pitch layouts | Select when >400 mW continuous dissipation is required and board space permits DO-41 |
| BZX55-C13 | 13 V nominal, ±5%, 500 mW, DO-35 package, higher ZZ (≤30 Ω) | Slightly higher dynamic impedance; same DO-34 footprint not guaranteed-verify mechanical fit | Choose if BOM consolidation with BZX55 family is prioritized and 30 Ω ZZ is acceptable |
Compared with RD13ES-T4-AZ, 1N4742A offers triple the power rating but requires PCB redesign for DO-41; BZX55-C13 matches voltage and tolerance but lacks DHD thermal enhancement and may not meet 400 mW derating curves at elevated ambient temperatures.

FAQ
What is the zener voltage tolerance for RD13ES-T4-AZ?
The RD13ES-T4-AZ has a zener voltage range of 12.18 V to 13.62 V at IZ = 5 mA, corresponding to a ±5% tolerance about the nominal 13 V rating. This is confirmed in the Electrical Characteristics table of Renesas datasheet D13935EJ7V0DS, where AB1/AB2/AB3 suffix variants define the min/max bounds for RD13ES.
Does RD13ES-T4-AZ support surge protection applications?
Yes, RD13ES-T4-AZ supports surge protection with a rated non-repetitive surge reverse power of 100 W for 10 µs pulses, as specified in the Absolute Maximum Ratings table. Its DHD construction enhances thermal response during transient events, making it suitable for clamping I/O line surges in industrial control equipment.
What is the maximum junction temperature rating for RD13ES-T4-AZ?
The RD13ES-T4-AZ has a maximum junction temperature (Tj) of +175°C and a minimum of –65°C, per the Absolute Maximum Ratings section. This wide range supports operation in demanding environments such as enclosed industrial enclosures or under-hood automotive auxiliary modules (non-safety-critical).
Is RD13ES-T4-AZ RoHS compliant?
Yes, RD13ES-T4-AZ is RoHS compliant. Renesas Electronics confirms environmental compliance-including EU RoHS Directive adherence-in its product documentation and public declarations. The DO-34 glass package contains no lead-based solder seals or restricted substances above threshold limits.
