Product details
Overview
RKZ2.2BKG#P1 from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power analog and reference circuits, featuring a nominal Zener voltage of 2.2 V ±5%, 700 mW power dissipation, 30 kΩ dynamic resistance at 10 mA test current, and ESD capability of ±30 kV (HBM). It operates as a shunt voltage reference in feedback loops of LDOs and sensor signal conditioning stages.
For engineers reviewing the RKZ2.2BKG#P1 datasheet, RKZ2.2BKG#P1 pinout, RKZ2.2BKG#P1 application, or RKZ2.2BKG#P1 equivalent, key selection criteria include tight Zener voltage tolerance (±5%), low temperature coefficient near zero crossing (~0.02 %/°C), surface-mount SRP-F package compatibility with high-density PCB layouts, and robust ESD immunity for industrial sensor interfaces.
Technical Context
This device uses a silicon planar junction structure optimized for stable Zener breakdown at low voltages (2.2 V), where avalanche and Zener mechanisms coexist. Its design targets minimal voltage drift over temperature and load, supported by a low dynamic resistance (30 Ω) and specified reverse current limit (≤10 µA at VR = 1 V).
The SRP-F flat-lead package enables thermal performance suitable for ambient temperatures up to +150°C junction, with derating defined per Figure 3. Electrical characteristics are validated under pulsed test conditions (Pw = 40 ms) to avoid self-heating artifacts during measurement.

FAQ
What is the exact Zener voltage tolerance for RKZ2.2BKG#P1?
The RKZ2.2BKG#P1 has a Zener voltage tolerance of ±5% at 10 mA test current, meaning its nominal 2.2 V rating falls between 2.09 V and 2.31 V across all units. This tolerance is verified per the REJ03G1700-0100 datasheet and applies under standard test conditions (Ta = 25°C, pulsed measurement).
Can RKZ2.2BKG#P1 be used in place of a 2.2 V Zener diode in an LDO feedback network?
Yes, RKZ2.2BKG#P1 is suitable for LDO feedback networks due to its low dynamic resistance (30 Ω max) and tight voltage tolerance (±5%). Its SRP-F package allows direct placement near the error amplifier input, minimizing parasitic inductance and improving transient response in RKZ2.2BKG#P1-based designs.
What is the maximum continuous reverse current RKZ2.2BKG#P1 can sustain without degradation?
RKZ2.2BKG#P1 is rated for continuous operation at up to 10 mA Zener current (IZ) under derated ambient conditions. At Ta = 25°C, this corresponds to ~22 mW dissipation. For sustained 10 mA operation, ensure junction temperature remains ≤150°C using the derating curve in Figure 3 of the RKZ2.2BKG#P1 datasheet.
Does RKZ2.2BKG#P1 meet automotive AEC-Q200 requirements?
No, RKZ2.2BKG#P1 is not AEC-Q200 qualified. It is classified as a Standard-grade Renesas product intended for industrial, consumer, and computing applications-not automotive or safety-critical systems. For AEC-Q200-compliant alternatives, consult Renesas' automotive Zener portfolio separately.
How does the SRP-F package of RKZ2.2BKG#P1 compare thermally to SOD-123?
The SRP-F package of RKZ2.2BKG#P1 offers comparable thermal resistance to SOD-123 (RθJA ≈ 220°C/W on standard FR-4), but with 35% smaller footprint (1.6 mm × 2.8 mm vs. 2.7 mm × 4.0 mm). Its flat-lead geometry improves solder joint reliability and reduces coplanarity issues during reflow-key advantages for RKZ2.2BKG#P1 in high-volume manufacturing.
