Product details
Overview
NZH30C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and overvoltage protection at 30 V nominal Zener voltage (VZ = 28.5–31.5 V @ IZ = 5 mA), with 250 Ω max differential resistance, 55 μA reverse current at 1 V, and AEC-Q101 qualification for automotive circuits.
For engineers reviewing the NZH30C,115 datasheet, NZH30C,115 pinout, NZH30C,115 application, or NZH30C,115 equivalent, this part supports stable 30 V reference generation in power supply feedback loops, ESD-robust sensor biasing, and compact automotive voltage clamping where thermal resistance to solder point (Rth(j-sp) = 70 K/W) and low capacitance (Cd = 50 pF @ 1 MHz) are critical.
Technical Context
This Zener diode operates as a two-terminal voltage reference device with cathode-anode polarity defined by a marking bar. It delivers regulated reverse breakdown at precisely controlled test currents (IZ = 5 mA), with specified differential resistance (250 Ω max) and low leakage (IR ≤ 0.04 μA @ VR = 1 V).
Its thermal performance is characterized under two mounting conditions: Rth(j-a) = 250 K/W on FR4 PCB and Rth(j-sp) = 70 K/W to cathode solder point - enabling accurate junction temperature estimation in space-constrained automotive modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30,215 | Same 30 V nominal VZ, but SOT23 package (larger footprint, higher Rth(j-a) = 300 K/W) | Less suitable for space-constrained automotive modules requiring SOD123F reflow compatibility | Select when legacy SOT23 board design exists and thermal budget allows higher junction rise |
| MMSZ5260ET1G | 30 V VZ, SOD123 package (not SOD123F), no AEC-Q101 qualification, 400 Ω rdif max | Not qualified for automotive use; higher dynamic impedance reduces regulation precision | Acceptable only for industrial non-automotive applications with relaxed stability and qualification requirements |
Compared with BZX84-C30,215 and MMSZ5260ET1G, NZH30C,115 offers superior thermal performance (Rth(j-sp) = 70 K/W), tighter VZ tolerance (±5%), and automotive qualification - making it the only choice for production-critical 30 V reference in AEC-compliant systems.

FAQ
What is the maximum continuous reverse current the NZH30C,115 can handle before degradation?
The NZH30C,115 has an absolute maximum forward current (IF) of 250 mA per IEC 60134 limiting values, but as a Zener diode, its safe continuous reverse current is governed by power dissipation limits: 500 mW on FR4 PCB (Tamb ≤ 25 °C) corresponds to ~16.7 mA at 30 V. Exceeding this without thermal derating risks junction overheating beyond 150 °C.
Does the NZH30C,115 support bidirectional transient suppression like a TVS diode?
No - the NZH30C,115 is a unidirectional Zener diode rated only for reverse-biased regulation. Its forward voltage is 0.9 V at 10 mA, and it lacks the symmetric breakdown characteristics or peak pulse power rating required for bidirectional TVS operation. Use dedicated automotive TVS devices (e.g., PESDxUSB30) for ESD or surge suppression.
How does the SOD123F package differ from standard SOD123 in thermal performance?
The SOD123F variant features flattened leads that improve solder joint reliability and reduce thermal resistance to the PCB: Rth(j-sp) is 70 K/W (vs. ~90–100 K/W for standard SOD123), and Rth(j-a) is 250 K/W on FR4 - a 15–20% improvement critical for sustained 500 mW operation in automotive ambient conditions.
Can NZH30C,115 be used in series or parallel configurations for higher voltage or current handling?
Series connection is not recommended due to mismatched Zener voltage tolerances (±5%) causing uneven voltage sharing. Parallel operation is discouraged because of thermal runaway risk - slight differences in VZ and rdif cause current hogging. For higher power, use a single higher-rated device or external current-limiting resistors with strict thermal isolation.
