Product details
Overview
RKZ6.2B2KJ#R1 from Renesas Electronics is a silicon planar Zener diode designed for precision voltage stabilization and transient surge absorption in low-power signal and supply rail protection circuits. It delivers a nominal Zener voltage of 6.2 V (min 6.06 V, max 6.33 V) at 5 mA, with dynamic resistance of 50 Ω, power dissipation of 150 mW, and ESD capability of ±30 kV (HBM). It is used in voltage reference circuits for sensor signal conditioning and microcontroller I/O clamp protection.
For engineers reviewing the RKZ6.2B2KJ#R1 datasheet, RKZ6.2B2KJ#R1 pinout, RKZ6.2B2KJ#R1 application, or RKZ6.2B2KJ#R1 equivalent, this page provides verified electrical parameters, UFP package dimensions, cathode/anode terminal roles, surge power derating curves, and validated alternative parts for voltage reference and ESD protection design-in.
Technical Context
This device operates as a two-terminal, reverse-biased voltage reference with tight tolerance (±1.7% at 6.2 V) and low temperature coefficient (≈+0.04 %/°C near 6.2 V, per Fig.2). Its ultra-small flat lead (UFP) package enables high-density SMT placement on space-constrained PCBs while maintaining thermal performance up to 150°C junction temperature.
The RKZ6.2B2KJ#R1 exhibits non-repetitive surge reverse power handling up to ~1.2 W for 1 ms pulses (per Fig.4 reference curve), and maintains stable Zener regulation down to 2 μA reverse current - enabling use in ultra-low-quiescent-current bias networks and battery-backed monitoring circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.06–6.33 V at IZ = 5 mA - ensures stable 6.2 V reference within ±1.7% tolerance for analog sensing and ADC reference buffering. |
| Dynamic Resistance (rd) | 50 Ω max at IZ = 5 mA - limits output impedance variation under load shifts, critical for noise-sensitive voltage references. |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - defines maximum continuous DC power; derates linearly above 25°C (see Fig.3). |
| Reverse Current (IR) | ≤2 μA at VR = 3.0 V - guarantees minimal leakage in standby mode, supporting low-power wake-up detection circuits. |
| ESD Capability | ±30 kV HBM (C = 150 pF, R = 330 Ω) - provides robust input/output port protection without external TVS stacking. |
| Junction Temperature (Tj) | −55°C to +150°C - supports operation in industrial ambient environments including automotive under-hood auxiliary modules. |
Pinout & Package
Package: Ultra Small Flat Lead (UFP), JEITA code PWSF0002ZA-A, SC-79 compatible, mass ≈ 0.0016 g. Dimensions: 1.10 mm × 0.70 mm × 0.30 mm (L × W × H), with 0.50 mm pitch and exposed lead tips for reliable solder wetting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher-potential node in reverse-bias configuration; carries regulated Zener current during clamping or reference operation. |
| 2 | Anode | Connected to lower-potential node (e.g., GND or signal return); completes current path during Zener conduction or ESD discharge. |
Key Features
| Feature | Design Value |
|---|---|
| Emboss taping reel packaging | Enables automated SMT placement with consistent orientation and zero tape jam risk in high-volume production. |
| Ultra-small UFP footprint | 1.10 × 0.70 mm area saves >60% board space vs. SOD-323, critical for wearables and miniaturized IoT sensors. |
| Tight Zener voltage tolerance | ±1.7% at 6.2 V eliminates need for post-assembly trimming in factory-calibrated voltage monitors. |
| High ESD immunity | ±30 kV HBM rating allows direct interface with unshielded connectors in industrial control panels without added protection diodes. |
| Low leakage at low VR | ≤2 μA at 3.0 V enables use in micropower brown-out detection circuits where quiescent current must stay below 5 μA. |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller I/O Clamp Protection |
|---|---|
Use Scenario: Stabilizing excitation voltage for resistive bridge sensors (e.g., pressure transducers) in PLC analog input modules. IC Role / Device Role / Timing Role: Two-terminal Zener reference providing precise 6.2 V bias to Wheatstone bridge, rejecting supply ripple. Use Value: Maintains <±0.5% full-scale accuracy over −40°C to +85°C ambient due to low tempco and stable rd. |

IC Role / Device Role / Timing Role: Fast-response Zener clamp limiting differential voltage to <6.5 V during 100 ns transients. Use Value: Prevents USB PHY latch-up with <1 ns response time and no signal integrity impact due to sub-0.5 pF junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference and ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C6V2 (Nexperia) | Same 6.2 V nominal Zener, but SOD-523 package (1.3 × 0.85 mm); rd = 60 Ω; Pd = 300 mW; ESD = ±30 kV. | Larger footprint and higher power rating suit higher-energy surge environments but require more PCB area. | Select when higher surge energy margin is needed and board space permits larger package. |
| MMSZ4687 (ON Semiconductor) | 6.2 V Zener, SOD-123 package (3.7 × 1.6 mm); rd = 70 Ω; Pd = 500 mW; ESD = ±30 kV; tighter initial tolerance (±5%). | Higher power and legacy footprint ease replacement in existing designs but lack UFP miniaturization. | Choose for drop-in replacement in legacy SOD-123 layouts where space is not constrained. |
Compared with BZX584-C6V2 and MMSZ4687, the RKZ6.2B2KJ#R1 offers the smallest footprint (UFP), lowest leakage (≤2 μA), and best dynamic resistance (50 Ω) - making it optimal for space- and power-critical new designs where precision and miniaturization outweigh raw power handling.

FAQ
What is the Zener voltage tolerance of RKZ6.2B2KJ#R1 at 5 mA?
The RKZ6.2B2KJ#R1 has a Zener voltage range of 6.06 V to 6.33 V at IZ = 5 mA, corresponding to a ±1.7% tolerance around the nominal 6.2 V rating. This tight tolerance is confirmed in the Electrical Characteristics table on page 2 of the REJ03G1588-0100 datasheet and eliminates need for post-production calibration in precision reference applications.
Does RKZ6.2B2KJ#R1 support surface-mount assembly, and what is its package type?
Yes, RKZ6.2B2KJ#R1 uses the Ultra Small Flat Lead (UFP) package (JEITA code PWSF0002ZA-A, SC-79 compatible), explicitly designed for reflow-compatible surface-mount assembly. Its 1.10 mm × 0.70 mm footprint and embossed taping enable high-yield pick-and-place with standard 0402 feeders, as stated in the Ordering Information section of the datasheet.
What is the maximum reverse leakage current for RKZ6.2B2KJ#R1 at 3.0 V?
The maximum reverse leakage current (IR) for RKZ6.2B2KJ#R1 is 2 μA at VR = 3.0 V, per the Electrical Characteristics table. This ultra-low leakage supports micropower applications such as battery voltage monitors and always-on wake-up comparators where standby current must remain below 5 μA.
Can RKZ6.2B2KJ#R1 be used for ESD protection, and what is its HBM rating?
Yes, RKZ6.2B2KJ#R1 is rated for ±30 kV HBM ESD protection (C = 150 pF, R = 330 Ω, 10 pulses in both directions), as specified in the Electrical Characteristics table. Its low dynamic resistance and fast turn-on make it effective for clamping electrostatic discharges on signal lines without requiring additional TVS components.
What is the thermal derating behavior of RKZ6.2B2KJ#R1 above 25°C ambient?
RKZ6.2B2KJ#R1 derates linearly from 150 mW at 25°C ambient, reaching 0 mW at 150°C, as shown in Fig.3 (Power Dissipation vs. Ambient Temperature). The slope is −1.25 mW/°C, meaning usable power drops to 125 mW at 45°C and 75 mW at 85°C - critical for thermal design in enclosed industrial enclosures.
