Product details
Overview
NZH22C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions at 22 V nominal working voltage (VZ = 21.08–22.17 V @ IZ = 5 mA), with ≤200 Ω differential resistance, ≤30 μA reverse current at 17 V, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the NZH22C,115 datasheet, NZH22C,115 pinout, NZH22C,115 application, or NZH22C,115 equivalent, this device supports stable 22 V clamping in low-power bias networks, ECU voltage references, and overvoltage protection circuits where thermal resistance to ambient (250 K/W on FR4) and compact SMD footprint are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ tolerance (±5% for NZH22C), specified at IZ = 5 mA and Tj = 25 °C. Its low differential resistance (≤200 Ω) ensures minimal voltage shift under load variation, while its 30 μA reverse leakage at VR = 17 V enables low-quiescent-current regulation.
The device is qualified per AEC-Q101 and rated for junction temperatures up to 150 °C, with thermal resistance from junction-to-ambient of 250 K/W (FR4 PCB) and 125 K/W (ceramic PCB). It uses a planar epitaxial process and features a cathode-marked SOD123F package optimized for reflow soldering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 22 V - precise DC voltage reference point at 5 mA test current |
| VZ range | 21.08–22.17 V - guaranteed regulation window under production tolerance |
| rdif | ≤200 Ω - low dynamic impedance maintains stable output under varying load |
| IR @ VR = 17 V | ≤30 μA - minimal leakage preserves efficiency in battery-backed or low-power rails |
| Ptot (Tamb ≤ 25 °C) | 500 mW - maximum continuous dissipation on standard FR4 PCB |
| Cd @ f = 1 MHz, VR = 0 V | 60 pF - low junction capacitance avoids signal coupling in high-frequency bias networks |
| Tj max | 150 °C - extended thermal capability supports under-hood automotive environments |
Pinout & Package
SOD123F is a 2-pin surface-mount plastic package measuring 3.6 × 1.7 × 1.0 mm (L × W × H), with flat leads and cathode marked by a bar on the body. Thermal pad area is optimized for solder land dimensions of 2.9 × 1.2 mm per lead (reflow footprint).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C22,115 | VZ = 22.0 V ±5%, rdif ≤ 500 Ω, Ptot = 300 mW, SOT23 package | Higher differential resistance and lower power rating limit use in higher-current regulation | Select when board space permits larger SOT23 and thermal budget is constrained to ≤300 mW |
| MMSZ5246B-7-F | VZ = 22.0 V ±5%, rdif ≤ 350 Ω, Ptot = 500 mW, SOD123 package (not F variant) | SOD123 lacks flattened leads and has higher Rth(j-sp) (150 K/W vs 125 K/W) | Choose only if legacy SOD123 footprint compatibility is required and thermal margin is ≥15 K/W |
Compared with BZX84-C22,115 and MMSZ5246B-7-F, NZH22C,115 delivers superior thermal performance on FR4 (250 K/W), tighter leakage control (30 μA vs ≥100 μA), and AEC-Q101 validation-making it the preferred choice for automotive and high-reliability industrial regulation where long-term stability and surge resilience are critical.

FAQ
What is the maximum reverse voltage (VR) that NZH22C,115 can block before breakdown?
NZH22C,115 exhibits ≤30 μA reverse current at VR = 17 V, confirming reliable blocking behavior below its 22 V nominal Zener voltage. Breakdown begins gradually above ~20 V, with full regulation established at 21.08 V minimum per datasheet Table 10. It is not rated for sustained operation above 22.17 V.
Can NZH22C,115 be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging when paralleled. The datasheet specifies single-device operation only. For >500 mW needs, use an active regulator or select a higher-rated device like PZU22BA (1 W, SOD323).
Is the SOD123F package compatible with standard SOD123 reflow footprints?
No-SOD123F has flattened leads and tighter dimensional tolerances (e.g., 0.35–0.55 mm lead thickness vs 0.5–0.7 mm for SOD123). Its recommended solder land is 2.9 × 1.2 mm per lead; using a legacy SOD123 footprint risks insufficient wetting and mechanical lift-off during reflow.
Does NZH22C,115 support bidirectional ESD protection?
No-it is a unidirectional Zener diode optimized for reverse-bias regulation only. Its forward voltage is 0.9 V at 10 mA, but it lacks symmetric clamping characteristics or IEC 61000-4-2 rating. For bidirectional ESD protection, use dedicated TVS arrays such as PESD5V0S1BA.
