Product details
Overview
RD6.2JS from Renesas Electronics is a 400 mW DO-34 glass-sealed Zener diode with nominal zener voltage 6.2 V (AB1 suffix: 5.86–6.12 V), dynamic impedance ≤60 Ω at 5 mA, reverse current ≤100 µA at 3.0 V, and sharp breakdown characteristic for precision voltage regulation in low-noise analog circuits.
For engineers reviewing the RD6.2JS datasheet, RD6.2JS pinout, RD6.2JS application, or RD6.2JS equivalent, this device serves as a stable reference in constant-voltage supplies, waveform clippers, and overvoltage protection where low noise and tight Vz tolerance are critical.
Technical Context
The RD6.2JS operates as a two-terminal voltage-reference device relying on controlled avalanche breakdown in silicon. Its DO-34 package enables axial lead mounting with thermal resistance of 375 °C/W (junction-to-ambient, free-air), and it exhibits a positive temperature coefficient near 6.2 V (γz ≈ +0.02 %/°C per Fig. 6).
It delivers sharp knee characteristics with knee dynamic impedance Zzk ≤1 Ω at low current (Iz = 1 mA), enabling clean clamping and stable biasing in signal conditioning paths. The device is rated for surge reverse power up to 2.4 W (10 µs pulse) and junction temperature up to 175 °C.
Key Specifications

|---|---|
| Zener Voltage Vz | 5.86–6.12 V (AB1 suffix, Iz = 5 mA); defines precise regulation point for reference circuits |
| Power Dissipation P | 400 mW (TA = 25 °C); sets maximum continuous DC power handling in free-air |
| Dynamic Impedance Zz | ≤60 Ω (Iz = 5 mA); ensures minimal output voltage variation under load current changes |
| Reverse Current IR | ≤100 µA at VR = 3.0 V; guarantees low leakage before breakdown onset |

| Package | DO-34 (JEDEC); axial glass-body package with blue cathode band, 2.4 mm max body length |
Pinout & Package
RD6.2JS is a two-terminal axial-leaded DO-34 glass package. Cathode is marked by a blue band; anode is unmarked end. No PCB footprint or orientation constraints beyond standard DO-34 mechanical clearance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward bias; reference ground node in reverse-biased regulator | Connected to lower-potential side of circuit; establishes reference return path |
| Cathode | Current exit terminal during forward bias; regulated output node in reverse-biased operation | Provides stable 6.2 V output relative to anode when reverse-biased above Vz |
Key Features
| Feature | Design Value |
|---|---|
| Low noise performance | en ≤ 40 µV (10–500 kHz, Fig. 8); minimizes added noise in precision references and audio bias networks |
| Sharp breakdown knee | Zzk ≤ 1 Ω at Iz = 1 mA (Fig. 2); enables accurate clamping and fast turn-on in protection circuits |
| E24-standard Vz grading | Vz tolerance aligned to E24 series (±5% typical); simplifies BOM consolidation across 4.7–39 V variants |
| DO-34 glass seal | Hermetic glass-to-metal seal; ensures long-term stability and moisture resistance in harsh ambient conditions |
Applications
| Constant Voltage Reference | Waveform Clipping |
|---|---|
Use Scenario: Providing stable 6.2 V reference for op-amp biasing and ADC voltage references in industrial sensor interfaces. IC Role / Device Role / Timing Role: Two-terminal passive voltage reference establishing fixed potential independent of supply variation. Use Value: Enables ±1% output accuracy over temperature due to low Zz and predictable γz, reducing calibration overhead. | Use Scenario: Limiting signal swing in audio preamplifier input stages to prevent op-amp saturation. IC Role / Device Role / Timing Role: Bidirectional clipping element using forward conduction (0.7 V) and reverse breakdown (6.2 V). Use Value: Sharp knee ensures symmetrical clipping thresholds and minimal distortion at crossover points. |
| Overvoltage Protection | Current Source Biasing |
Use Scenario: Safeguarding microcontroller I/O pins against ESD-induced transients in embedded control panels. IC Role / Device Role / Timing Role: Shunt clamp absorbing surge energy above 6.2 V while holding downstream node voltage. Use Value: 2.4 W surge rating (10 µs) provides robust transient immunity without external TVS supplementation. | Use Scenario: Setting bias current for JFET amplifiers in RF front-end gain blocks.

Use Value: Low dynamic impedance maintains current stability despite supply ripple, improving amplifier linearity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4735A | 6.2 V nominal, 1 W rating, DO-41 package, Zz = 7 Ω (20 mA) | Higher power and lower Zz but larger footprint and higher leakage (5 µA @ 4.96 V) | Preferred when >400 mW dissipation or <10 Ω Zz is required; requires PCB layout change |
| BZX55C6V2 | 6.2 V nominal, 500 mW rating, DO-35 package, Zz = 10 Ω (5 mA) | Lower Zz and tighter Vz tolerance (±5%), but glass DO-35 has lower surge capability (1.5 W) | Suitable for space-constrained designs needing improved regulation; verify surge margin in transient-heavy environments |
Compared with RD6.2JS, 1N4735A offers higher power and lower impedance but demands larger board area, while BZX55C6V2 improves regulation precision in smaller DO-35 form factor at reduced surge resilience - both require revalidation of thermal and transient margins.

FAQ
What is the exact zener voltage range for RD6.2JS under standard test conditions?
The RD6.2JS AB1 variant has a guaranteed zener voltage range of 5.86 V to 6.12 V when tested at Iz = 5 mA and TA = 25 °C, per the Electrical Characteristics table in Renesas datasheet D13937EJ5V0DS00. This range reflects E24-series grading and is confirmed across production lots.
Does RD6.2JS have a specified temperature coefficient, and how does it affect circuit stability?
Yes, RD6.2JS exhibits a positive temperature coefficient of approximately +0.02 %/°C (or +1.2 mV/°C) near 6.2 V, as shown in Fig. 6 of the datasheet. This means its zener voltage increases linearly with junction temperature - a key factor when designing temperature-critical references or compensating bias networks.
Can RD6.2JS be used in surface-mount designs?
No, RD6.2JS is exclusively offered in the through-hole DO-34 axial glass package and has no SMD variant. It requires hole-mounting and lead forming. For surface-mount equivalents, consider BZX55C6V2 (DO-35) or MMBZ5231B (SOT-23), though these differ in thermal and electrical behavior.
What is the maximum allowable reverse surge power for RD6.2JS, and under what conditions?
RD6.2JS supports a non-repetitive surge reverse power of 2.4 W for pulse width t = 10 µs, as defined in Absolute Maximum Ratings and illustrated in Fig. 9. This rating assumes single-event transients; repeated surges must respect average power limits and thermal derating curves in Fig. 5.
Is RD6.2JS compliant with RoHS and lead-free soldering requirements?
Yes, RD6.2JS meets EU RoHS Directive requirements. Renesas confirms environmental compliance in product documentation and supports lead-free reflow profiles; the DO-34 glass package is inherently compatible with standard Pb-free soldering processes up to 260 °C peak.
