Product details
Overview
NZH24C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and overvoltage protection in low-power circuits. It delivers a nominal Zener voltage of 24 V at IZ = 5 mA, with maximum differential resistance of 200 Ω, reverse current ≤ 0.04 μA at 19.2 V, and total power dissipation up to 500 mW on FR4 PCB - used in automotive body control modules for ECU reference rail stabilization.
For engineers reviewing the NZH24C,115 datasheet, NZH24C,115 pinout, NZH24C,115 application, or NZH24C,115 equivalent, key selection criteria include Zener voltage tolerance (±4.3%), thermal resistance (250 K/W junction-to-ambient), AEC-Q101 qualification, and SOD123F footprint compatibility with automated reflow assembly.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC reference voltages under varying load and temperature conditions. Its 24 V nominal working voltage is specified at IZ = 5 mA, with tight min/max bounds (23.12–24.31 V) and low dynamic impedance ensuring minimal output drift across operating current range.
The device features low capacitance (19 pF at 1 MHz, VR = 0 V) and ultra-low leakage (≤0.04 μA at VR = 19.2 V), enabling use in noise-sensitive analog sensing front-ends and high-impedance bias networks where parasitic loading must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 23.12–24.31 V at IZ = 5 mA - defines regulated output range for 24 V reference rails |
| Differential Resistance rdif | 200 Ω max - limits output voltage variation under ±1 mA load current change |
| Reverse Current IR | ≤0.04 μA at VR = 19.2 V - ensures negligible quiescent power loss in standby mode |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - supports polarity-check functionality without excessive forward drop |
| Total Power Dissipation Ptot | 500 mW (FR4 PCB) / 1 W (ceramic PCB) - sets maximum continuous power handling in standard vs. high-reliability layouts |
| Junction Temperature Tj | −55 °C to +150 °C - enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability per stress test requirements for discrete semiconductors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C24,115 | Same SOD123F package but ±5% VZ tolerance (22.8–25.2 V); higher rdif (300 Ω); not AEC-Q101 qualified | Limited to commercial-grade consumer power supplies; unsuitable for automotive BCU deployment | Select when cost sensitivity outweighs automotive qualification and tighter regulation needs |
| MMSZ5245B-TP | SOD123 package (slightly larger footprint); ±5% VZ; 200 Ω rdif; no AEC-Q101 status; 350 mW Ptot rating | Acceptable for industrial sensor biasing but lacks thermal margin for under-hood use | Choose only if existing board layout accommodates 3.7 mm × 1.6 mm SOD123 and AEC-Q101 is not required |
Compared with BZX84-C24,115 and MMSZ5245B-TP, NZH24C,115 offers superior voltage accuracy (±4.3% vs. ±5%), guaranteed automotive qualification, and higher power handling on standard FR4 - making it the sole option for AEC-compliant 24 V reference designs requiring long-term stability.

FAQ
What is the Zener voltage tolerance for NZH24C,115 at 5 mA test current?
The nominal Zener voltage is 24 V, with a guaranteed range of 23.12 V to 24.31 V at IZ = 5 mA - representing ±4.3% tolerance. This is tighter than standard ±5% Zeners and verified per Table 10 in the May 2024 datasheet revision.
Is NZH24C,115 suitable for reflow soldering on FR4 PCBs?
Yes - the SOD123F package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Recommended footprint dimensions are 2.9 mm × 1.6 mm per Fig. 5, with peak temperature ≤260 °C and time above liquidus ≤60 seconds.
How does the thermal resistance of NZH24C,115 impact its power derating?
Rth(j-a) is 250 K/W on FR4 PCB. At 70 °C ambient, maximum allowable power drops to ~320 mW (calculated as (150 − 70) / 250), requiring design-level derating below the 500 mW rated limit for sustained operation.
Does NZH24C,115 have any special marking or identification features?
Yes - it uses the marking code "D6", printed adjacent to the cathode bar on the device top surface, as confirmed in Table 4 of the datasheet. The bar itself indicates the cathode terminal (Pin 1), critical for correct orientation during placement.
