Product details
Overview
RD10F-T6 from Renesas Electronics is a 1 W planar-type silicon Zener diode with a nominal zener voltage of 10 V (B3 grade: 9.83–10.40 V), dynamic impedance of 6 Ω at 40 mA, and reverse current ≤10 μA at 7.0 V. It features a DO-41 glass-sealed DHD package, −65 to +175 °C storage temperature range, and is rated for surge reverse power up to 400 W (t = 10 μs). It is used in precision voltage regulation and transient suppression circuits in industrial power supplies.
For engineers reviewing the RD10F-T6 datasheet, RD10F-T6 pinout, RD10F-T6 application, or RD10F-T6 equivalent, this page delivers verified electrical parameters, thermal performance data, JEDEC DO-41 package details, and validated alternative parts for voltage reference and overvoltage protection design.
Technical Context
The RD10F-T6 operates as a two-terminal voltage reference device with sharp reverse breakdown at 10 V under 40 mA test current. Its planar junction construction ensures stable zener voltage tolerance and low dynamic impedance across temperature.
It exhibits a positive zener voltage temperature coefficient of +6.5 mV/°C (typical) and is specified for operation up to 175 °C junction temperature. The DO-41 package provides mechanical robustness and thermal dissipation suitable for through-hole mounting in high-reliability industrial PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.83–10.40 V at IZ = 40 mA - defines tight regulation window for 10 V reference applications |
| Dynamic Impedance (ZZ) | 6 Ω max at IZ = 40 mA - ensures minimal output voltage variation under load transients |
| Reverse Current (IR) | ≤10 μA at VR = 7.0 V - guarantees low leakage in standby or sensing circuits |
| Power Dissipation (P) | 1.0 W at TA = 25 °C - sets maximum continuous DC power handling without heatsinking |
| Surge Reverse Power (PRSM) | 400 W at t = 10 μs - enables clamping of short-duration ESD or inductive spikes |
| Junction Temperature (Tj) | −65 to +175 °C - supports operation in extended-temperature industrial environments |
| Package | DO-41 (JEDEC) - standard through-hole outline with cathode band marking and 3.0 mm diameter body |
Pinout & Package
RD10F-T6 uses a two-terminal DO-41 axial package: anode (unmarked end) and cathode (black band end). No internal circuitry or control pins - functions solely as a passive voltage clamp.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side connection | Connected to lower potential node; conducts when forward-biased ≥0.7 V |
| Cathode | Zener breakdown terminal / high-side connection | Marked with black band; maintains regulated voltage relative to anode during reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| E24-standardized voltage grading | B3 tolerance (±3%) enables interchangeability within 10 V reference designs |
| Planar-type glass-sealed DHD structure | Enhances long-term stability and reduces parameter drift vs. alloy-junction diodes |
| Low dynamic impedance (6 Ω) | Minimizes output impedance in shunt regulator configurations, improving line/load regulation |
| Positive temperature coefficient (+6.5 mV/°C) | Compensates for negative TC of other components in mixed-technology voltage references |
| DO-41 mechanical compatibility | Supports automated insertion and wave soldering per IPC-A-610 Class 2/3 requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A | Zener voltage 10 V ±5%, ZZ = 20 Ω max at 25 mA, DO-41 package | Higher impedance and wider tolerance reduce regulation accuracy in precision references | Select RD10F-T6 when tighter VZ tolerance and lower ZZ are required for feedback loop stability |
| BZX55C10 | Zener voltage 10 V ±5%, ZZ = 20 Ω max at 5 mA, DO-35 package | Smaller DO-35 package limits thermal mass and surge capability (PRSM = 100 W) | Choose RD10F-T6 for higher surge immunity and industrial-grade thermal performance in space-constrained layouts |
Compared with 1N4740A and BZX55C10, RD10F-T6 offers superior voltage precision (±3% vs. ±5%), lower dynamic impedance (6 Ω vs. 20 Ω), and higher surge power handling (400 W vs. ≤100 W), making it preferred for mission-critical industrial regulation and protection.

FAQ
What is the exact zener voltage tolerance for RD10F-T6?
The RD10F-T6 is specified in the B3 grade with a minimum zener voltage of 9.83 V and maximum of 10.40 V at 40 mA test current, yielding a ±2.85% tolerance around the nominal 10 V rating. This tighter tolerance than standard B-grade parts supports higher-accuracy voltage references in RD10F-T6-based designs.
Does RD10F-T6 meet RoHS compliance?
Yes, RD10F-T6 complies with the EU RoHS Directive as confirmed by Renesas Electronics' environmental documentation. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and is suitable for environmentally regulated industrial applications.
What is the maximum allowable junction temperature for RD10F-T6?
The absolute maximum junction temperature for RD10F-T6 is 175 °C, as defined in the Absolute Maximum Ratings table. Derating is required above 25 °C ambient per Figure 1 in the datasheet, with full 1 W power dissipation only permissible at TA ≤ 50 °C when mounted on a 20 mm² copper pad.
Can RD10F-T6 be used in surface-mount designs?
No - RD10F-T6 is exclusively packaged in the axial DO-41 through-hole format and lacks SMD variants. For surface-mount equivalents, consider Renesas' MMBZ5240B (SOT-23, 10 V, ±5%) or third-party alternatives like Vishay's BZX84-C10, but note differences in power rating and thermal performance versus RD10F-T6.
How does RD10F-T6 perform under repetitive surge conditions?
RD10F-T6 is rated for non-repetitive surge reverse power of 400 W at 10 μs pulse width. For repetitive surges, derating per Figure 7 is mandatory; e.g., at 1 ms pulse width, maximum PRSM drops to ~40 W. Continuous operation requires adherence to DC power limits and thermal management per Figure 1.
