Product details

Overview

NZH7V5C,115 from Nexperia is a single AEC-Q101-qualified Zener diode in SOD123F package, designed for precision voltage regulation at 7.5 V nominal working voltage (V_Z = 7.29–7.67 V @ I_Z = 20 mA), with low differential resistance (120 Ω max), reverse current ≤0.5 μA @ V_R = 5 V, and total power dissipation up to 500 mW on FR4 PCB - used in automotive body control modules for stable reference generation.

For engineers reviewing the NZH7V5C,115 datasheet, NZH7V5C,115 pinout, NZH7V5C,115 application, or NZH7V5C,115 equivalent, key selection criteria include Zener voltage tolerance (±2.5%), thermal resistance (250 K/W junction-to-ambient), cathode/anode polarity marking, and AEC-Q101 qualification for under-hood voltage clamping and biasing.

Technical Context

This Zener diode operates as a two-terminal voltage reference device with fixed breakdown behavior, specified at I_Z = 20 mA and T_j = 25 °C. Its 7.5 V nominal Zener voltage falls within the mid-range of the NZH series (3.0–30 V), optimized for low-noise regulation where differential resistance (120 Ω max) and capacitance (150 pF @ 1 MHz, V_R = 0 V) are critical.

The SOD123F package enables surface-mount integration with defined thermal performance: R_th(j-a) = 250 K/W (FR4), R_th(j-sp) = 125 K/W (ceramic Al₂O₃), and maximum junction temperature of 150 °C - supporting operation across −55 °C to +150 °C ambient range in automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_Z (nominal)	7.5 V; precise regulation point with ±2.5% tolerance (7.29–7.67 V @ 20 mA)
r_dif	120 Ω max; ensures stable output voltage under load variation

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C7V5,215	Same 7.5 V nominal V_Z, but SOT23 package (larger footprint, higher R_th(j-a) = 300 K/W)	Limited to lower-power consumer applications due to 350 mW P_tot rating	Select if board layout permits larger package and AEC-Q101 is not required
MMSZ5235B-7-F	7.5 V V_Z, SOD123 package (not SOD123F), 500 mW rating, but no AEC-Q101 qualification	Not validated for automotive temperature cycling or humidity robustness	Acceptable for industrial non-automotive designs where qualification is not mandated

Compared with BZX84-C7V5,215 and MMSZ5235B-7-F, NZH7V5C,115 delivers superior thermal performance on FR4 (250 vs. 300 K/W), guaranteed automotive qualification, and tighter V_Z tolerance - making it the only choice for production-critical automotive voltage references.

FAQ

What is the maximum reverse current for NZH7V5C,115 at 5 V?

The maximum reverse current (I_R) is 0.5 μA at V_R = 5 V and T_j = 25 °C, per Table 8 in the datasheet. This ultra-low leakage supports precision biasing in low-power sensor front-ends and maintains accuracy during system sleep modes.

Is NZH7V5C,115 suitable for reflow soldering only?

Yes - the datasheet explicitly states "Reflow soldering is the only recommended soldering method" for the SOD123F package. Hand soldering or wave soldering is not qualified and may compromise thermal reliability or mechanical integrity of the leadframe bond.

How does the SOD123F package differ thermally from standard SOD123?

SOD123F features a flat lead design that improves thermal conduction to the PCB: R_th(j-sp) is 125 K/W on ceramic versus 250 K/W on FR4, compared to ~300 K/W for legacy SOD123. This enables higher sustained power dissipation in compact automotive layouts.

Does NZH7V5C,115 require external current limiting in regulation mode?

Yes - like all Zener diodes, it requires a series current-limiting resistor to set I_Z within 1–20 mA range. The resistor value must ensure I_Z stays below 250 mA absolute maximum forward current and maintains power within 500 mW on FR4 or 1 W on ceramic substrates.
