Product details

Overview

NZH27C,115 from Nexperia is a single AEC-Q101-qualified Zener diode in SOD123F package, designed for precision voltage regulation and overvoltage protection at 27 V nominal working voltage (V_Z = 25.63–26.95 V @ I_Z = 5 mA), with 250 Ω max differential resistance, 45 μA reverse current at 1 V, and 21 pF capacitance at 1 MHz. It operates across –55 °C to +150 °C ambient and supports automotive power rail clamping.

For engineers reviewing the NZH27C,115 datasheet, NZH27C,115 pinout, NZH27C,115 application, or NZH27C,115 equivalent, key selection criteria include its AEC-Q101 qualification, 27 V regulation tolerance, thermal resistance of 125 K/W (junction-to-solder point), and SOD123F footprint compatibility with high-density PCB layouts.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its low differential resistance (250 Ω max) ensures tight regulation across 5 mA test current, while AEC-Q101 qualification confirms robustness against automotive-grade thermal cycling, humidity, and mechanical stress.

The device exhibits 21 pF junction capacitance at 0 V and 1 MHz, enabling use in moderate-speed transient suppression without signal distortion. Its 150 °C maximum junction temperature and 1 W peak power dissipation on ceramic PCB support operation in engine control units and body electronics with limited heatsinking.

Key Specifications

Parameter	Value and Actual Design Meaning
V_Z (nom)	27 V - nominal Zener voltage at 5 mA; actual range 25.63–26.95 V ensures ±2.5% regulation accuracy in feedback loops
r_dif	250 Ω max - low dynamic impedance maintains stable output under load transients up to 5 mA
I_R @ 1 V	45 μA max - low leakage enables reliable standby-mode voltage monitoring in battery-powered systems
C_d	21 pF @ 1 MHz, 0 V - minimal capacitive loading preserves signal integrity in 10–100 MHz sensor interface rails
P_tot	1 W max on Al₂O₃ PCB - sufficient headroom for short-duration surge clamping in 12 V/24 V automotive subsystems
T_j max	150 °C - supports continuous operation in under-hood ECUs without active cooling
AEC-Q101	Qualified - validated for automotive applications including temperature cycling, HTRB, and ESD per JESD22-A110

Use Scenario: Protecting 4–20 mA current-loop receiver inputs from field-wiring induced surges in factory automation cabinets.

IC Role / Device Role / Timing Role: Standby-mode voltage regulator and transient suppressor placed between input terminals and signal conditioning ICs.

Use Value: 45 μA reverse leakage at 1 V prevents false triggering in low-current analog circuits while maintaining <1% error at full scale.

Automotive Body Control Module (BCM)

Medical Infusion Pump Power Monitoring

Use Scenario: Providing stable 27 V reference for window lift motor current sensing in door modules.

IC Role / Device Role / Timing Role: Precision voltage reference source feeding comparator inputs that detect motor stall or obstruction.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C27	Same 27 V nominal V_Z, but SOT23 package (larger footprint); 350 Ω r_dif; not AEC-Q101 qualified	Limited to consumer/industrial use; unsuitable for automotive due to lack of stress-test validation	Select when cost sensitivity outweighs automotive compliance and board space is unconstrained
MMSZ5256B	SOD-123 package variant; 27 V V_Z, 200 Ω r_dif; AEC-Q101 qualified; 30 μA I_R @ 1 V	Lower leakage improves accuracy in ultra-low-power sleep modes but higher capacitance (30 pF) limits high-frequency response	Prefer for battery-backed systems where standby current <1 μA is critical, accepting minor bandwidth trade-off

Compared with BZX84-C27 and MMSZ5256B, NZH27C,115 delivers optimal balance of automotive qualification, thermal performance (125 K/W R_th(j-sp)), and low-capacitance transient response-making it the preferred choice for space-constrained, high-reliability 27 V regulation in engine and body electronics.

FAQ

What is the maximum reverse current (I_R) specification for NZH27C,115 at 1 V?

The maximum reverse current is 45 μA at VR = 1 V and Tj = 25 °C, measured per Table 10 of the datasheet. This value remains stable across –40 °C to +125 °C ambient, supporting accurate low-leakage biasing in precision analog circuits without significant temperature-induced drift.

Is NZH27C,115 compatible with lead-free reflow soldering processes?

Yes-Nexperia specifies reflow soldering as the only recommended method for SOD123F packages. The device meets JEDEC J-STD-020 moisture sensitivity level 1 and supports peak temperatures up to 260 °C for ≤30 seconds, fully compliant with IPC-7095B Class 3 assembly requirements.

How does the thermal resistance R_th(j-sp) of 125 K/W impact PCB layout?

This value reflects junction-to-solder-point resistance when mounted on ceramic PCB (Al₂O₃). To achieve it, the cathode pad must be connected to ≥1 cm² of 35 μm copper with thermal vias to internal ground planes-ensuring safe operation at 500 mW continuous dissipation without exceeding 150 °C junction temperature.

Can NZH27C,115 replace older NZH27B variants in existing designs?

No-NZH27C uses I_Z = 5 mA test condition and tighter V_Z tolerance (±2.5%) versus NZH27B's I_Z = 20 mA and ±5% spec. Substitution may cause regulation drift in feedback networks calibrated for higher test current; redesign verification is required before replacement.
