Product details
Overview
RD6.2F(N)-T6 from Renesas Electronics is a 1 W planar-type silicon Zener diode with nominal zener voltage of 6.2 V, dynamic impedance of 6 Ω at 40 mA, and temperature coefficient of +2.0 mV/°C. It features DO-41 glass-sealed DHD (Double Heatsink Diode) packaging and is rated for surge reverse power up to 400 W (t = 10 μs), making it suitable for precision voltage regulation and transient suppression in industrial power supplies.
For engineers reviewing the RD6.2F(N)-T6 datasheet, RD6.2F(N)-T6 pinout, RD6.2F(N)-T6 application, or RD6.2F(N)-T6 equivalent, key selection criteria include its ±5% zener voltage tolerance (B grade), low dynamic impedance, positive temperature coefficient, and JEDEC DO-41 mechanical compatibility for through-hole PCB mounting in legacy and cost-sensitive designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 40 mA and maintains stable regulation across ambient temperatures from −65°C to +175°C. Its junction temperature limit is 175°C, and thermal resistance is optimized via the DHD structure for improved heat dissipation in compact layouts.
The device exhibits a typical zener voltage temperature coefficient of +2.0 mV/°C, indicating predictable voltage drift under thermal variation-critical for reference circuits requiring moderate stability without active compensation. Surge capability is defined at 400 W for 10 μs pulses, supporting basic transient protection in DC rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.17 V to 6.52 V at IZ = 40 mA - defines regulated output voltage range under standard test conditions |
| Dynamic Impedance (ZZ) | 6 Ω max at IZ = 40 mA - determines regulation stiffness and output voltage ripple sensitivity |
| Power Dissipation (P) | 1.0 W at TA = 25°C - sets maximum continuous DC power handling before thermal derating applies |
| Surge Reverse Power (PRSM) | 400 W for t = 10 μs - enables single-event transient absorption without failure in non-repetitive surge scenarios |
| Zener Temp. Coefficient (γZ) | +2.0 mV/°C typical - indicates voltage increases linearly with temperature, useful for temperature-compensated references |
| Reverse Current (IR) | 20 μA max at VR = 4.0 V - ensures low leakage below knee voltage, minimizing standby power loss |
| Junction Temperature (Tj) | 175°C maximum - defines absolute thermal limit for reliability under sustained load |
Pinout & Package
RD6.2F(N)-T6 uses a standard DO-41 axial-leaded package with cathode indicated by a black band. The device has two terminals: anode and cathode. No internal circuitry or multi-pin configuration is present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower potential side in reverse-biased Zener operation; carries forward current up to 200 mA |
| Cathode | Breakdown voltage reference terminal | Marked with black band; connected to higher potential side during regulation; defines VZ reference point |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | Same 6.2 V nominal rating, but 10% tolerance (±5% for RD6.2F(N)-T6 B grade), higher ZZ (7 Ω vs. 6 Ω), DO-41 package | Lower precision and slightly worse regulation; widely available but less stable over temperature | Select when cost is primary and tighter voltage control is not required |
| BZX55C6V2 | 6.2 V nominal, 5% tolerance, ZZ = 10 Ω max, DO-35 package (smaller, lower power) | Rated for only 500 mW; unsuitable for 1 W continuous operation or high-surge environments | Select only for space-constrained low-power applications where thermal margin is sufficient |
Compared with 1N4735A and BZX55C6V2, RD6.2F(N)-T6 offers superior regulation precision (tighter VZ spread), lower dynamic impedance, and full 1 W power handling in the robust DO-41 DHD package-making it preferred for industrial-grade voltage references and surge-prone power rails.

FAQ
What is the zener voltage tolerance for RD6.2F(N)-T6?
The RD6.2F(N)-T6 is manufactured to the B grade specification, with a zener voltage range of 6.17 V to 6.52 V at 40 mA test current-corresponding to ±5% tolerance around the nominal 6.2 V rating. This tight tolerance supports precision regulation without post-production sorting, and is confirmed in Renesas' D13936EJ5V0DS datasheet, page 3.
Does RD6.2F(N)-T6 have a positive or negative temperature coefficient?
RD6.2F(N)-T6 has a typical zener voltage temperature coefficient of +2.0 mV/°C, meaning its breakdown voltage increases linearly with rising junction temperature. This behavior is characteristic of mid-voltage Zeners (~5–6 V) and is documented in the "Electrical Characteristics" table of the official datasheet (page 3).
What package type does RD6.2F(N)-T6 use, and is it RoHS compliant?
RD6.2F(N)-T6 uses a JEDEC-standard DO-41 axial-leaded glass package with black cathode marking. While the 2006 datasheet predates full RoHS enforcement, Renesas confirms all current production RD6.2F(N)-T6 units meet EU RoHS Directive requirements, including lead-free terminations and compliant molding compounds.
Can RD6.2F(N)-T6 replace 1N4735A in existing designs?
Yes, RD6.2F(N)-T6 is mechanically and electrically compatible with 1N4735A-both use DO-41 packages and share 6.2 V nominal zener voltage-but RD6.2F(N)-T6 offers tighter tolerance (±5% vs. ±10%), lower dynamic impedance (6 Ω vs. 7 Ω), and higher surge rating (400 W vs. 250 W), making it a performance upgrade without PCB changes.
What is the maximum continuous forward current for RD6.2F(N)-T6?
The absolute maximum forward current for RD6.2F(N)-T6 is 200 mA at TA = 25°C, as specified in the "Absolute Maximum Ratings" table (page 2 of D13936EJ5V0DS). This rating applies only during forward conduction; the device is intended for reverse-bias regulation, and sustained forward operation above 100 mA requires thermal verification.
