Product details
Overview
NZH20C,115 from Nexperia is a single Zener diode in SOD123F package, designed for precision voltage regulation and reference functions in automotive and industrial power rails. It delivers a nominal Zener voltage of 20.0 V at IZ = 10 mA, with differential resistance ≤ 200 Ω, reverse current ≤ 0.04 μA at VR = 15 V, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the NZH20C,115 datasheet, NZH20C,115 pinout, NZH20C,115 application, or NZH20C,115 equivalent, this page provides verified Zener voltage tolerance (±2.5%), thermal resistance (Rth(j-a) = 250 K/W on FR4), cathode/anode polarity marking, and automotive-grade reliability data - all critical for ESD-robust biasing and overvoltage clamping designs.
Technical Context
The NZH20C,115 operates as a two-terminal voltage reference device, leveraging avalanche breakdown in silicon to maintain stable reverse-bias voltage across varying load currents. Its low differential resistance (≤200 Ω) ensures minimal voltage drift under dynamic current conditions, while its 0.04 μA reverse leakage at 15 V supports high-impedance sensing nodes.
AEC-Q101 qualification confirms operation across −55 °C to +150 °C ambient, and the SOD123F package enables compact PCB layout with defined thermal path to solder point (Rth(j-sp) = 70 K/W). The cathode-marking bar and standardized anode/cathode pinning ensure unambiguous orientation during automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 19.23 V to 20.22 V at IZ = 10 mA - tight ±2.5% tolerance enables accurate 20 V rail regulation without trimming |
| Differential Resistance rdif | ≤ 200 Ω - low impedance stabilizes output against load transients in feedback networks |
| Reverse Current IR | ≤ 0.04 μA at VR = 15 V - negligible leakage preserves battery life in always-on circuits |
| Forward Voltage VF | ≤ 0.9 V at IF = 10 mA - low conduction loss when used bidirectionally or as clamp |
| Total Power Dissipation Ptot | 500 mW (FR4 PCB) / 1 W (ceramic PCB) - defines maximum continuous power handling in real board environments |
| Junction Temperature Tj | −55 °C to +150 °C - validated operating range for engine control units and ADAS modules |
| Thermal Resistance Rth(j-a) | 250 K/W (FR4) - determines temperature rise above ambient under steady-state dissipation |
Pinout & Package
SOD123F is a surface-mount plastic package measuring 3.6 mm × 1.7 mm × 1.0 mm (L × W × H), with gull-wing leads and cathode identification via a molded bar marking on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms the reference return path in shunt regulator topology |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity, and mechanical shock per JESD22 standards |
| Low differential resistance | ≤200 Ω ensures <±20 mV output shift over 5–15 mA Zener current variation - critical for ADC reference stability |
| Small SOD123F footprint | 3.6 mm × 1.7 mm area allows dense placement near IC power pins without compromising thermal relief |
| Low reverse leakage | 0.04 μA at 15 V enables use in ultra-low-power wake-up circuits and battery-backed memory retention |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C20,115 | Same SOD123F package but ±5% VZ tolerance (19.0–21.0 V); higher rdif (≤300 Ω); not AEC-Q101 qualified | Limited to commercial-grade consumer electronics; unsuitable for automotive safety-critical rails | Select only if cost sensitivity outweighs temperature stability and automotive compliance requirements |
| MMSZ5248B-TP | SOD-123 package (identical outline), ±5% VZ, rdif ≤ 350 Ω, Ptot = 500 mW, no AEC-Q101 certification | Acceptable for industrial non-safety applications; lacks extended temperature validation and automotive test history | Prefer when sourcing flexibility across multiple distributors is prioritized over automotive qualification documentation |
Compared with BZX84-C20,115 and MMSZ5248B-TP, NZH20C,115 offers tighter voltage tolerance (±2.5% vs. ±5%), lower dynamic impedance (200 Ω vs. ≥300 Ω), and full AEC-Q101 traceability - making it the sole choice for ASIL-B compliant voltage references in automotive power management.

FAQ
What is the maximum continuous Zener current for NZH20C,115 at 25 °C ambient?
The absolute maximum forward current is 250 mA per limiting values table, but continuous Zener operation is constrained by power dissipation. At 20 V and 500 mW rating on FR4, the practical max continuous IZ is 25 mA. Exceeding this requires ceramic PCB mounting or derating per thermal resistance curves.
Does NZH20C,115 support bidirectional ESD protection?
No - NZH20C,115 is a unidirectional Zener diode optimized for reverse-bias regulation. Its forward voltage is 0.9 V at 10 mA, but it lacks symmetric clamping characteristics or specified ESD ratings like IEC 61000-4-2. For bidirectional protection, dedicated TVS diodes such as PESD5V0S1BA should be used.
How is the cathode identified on the SOD123F package?
The cathode is marked by a visible molded bar on the top surface of the SOD123F body, aligned with Pin 1. This matches the pinning diagram in the datasheet and corresponds to the "K" terminal in electrical schematics. The anode (Pin 2) has no marking and is located opposite the bar.
Can NZH20C,115 replace older NZH20B variants in existing designs?
Yes - NZH20C,115 shares identical SOD123F package, pinout, and Zener voltage range (19.23–20.22 V) with NZH20B, but offers improved differential resistance (≤200 Ω vs. ≤250 Ω) and updated AEC-Q101 test reporting. No layout or schematic changes are required for drop-in replacement.
