Product details
Overview
BZX585-C10,115 from Nexperia is a ±5 % tolerance Zener diode in SOD523 (SC-79) package, rated for 10 V nominal Zener voltage at 5 mA, 300 mW total power dissipation, and 40 W non-repetitive peak reverse power. It delivers low differential resistance (25 Ω typ. at IZ = 5 mA) and operates across −65 °C to +150 °C junction temperature, serving as a precision voltage reference in space-constrained power rail regulation.
For engineers reviewing the BZX585-C10,115 datasheet, BZX585-C10,115 pinout, BZX585-C10,115 application, or BZX585-C10,115 equivalent, this device is selected for compact DC voltage stabilization where tight tolerance, thermal stability, and surge resilience are required in portable electronics, sensor biasing, and low-power microcontroller reset circuits.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified 10 V nominal working voltage (VZ = 9.50 V min / 10.50 V max at IZ = 5 mA), exhibiting a temperature coefficient of +4.5 to +8.0 mV/K and reverse current ≤ 0.2 µA at VR = 7.6 V. Its low 25 Ω typical differential resistance ensures stable regulation under varying load currents.
The device uses an ultra-small SOD523 plastic surface-mount package with cathode-marked lead configuration, optimized for high-density PCB layouts. Thermal resistance from junction to ambient is 350 K/W on FR4 with 35 mm² copper area, supporting reliable operation up to 150 °C junction temperature.
Key Specifications

FAQ
What is the maximum continuous reverse current the BZX585-C10,115 can sustain?
The device has no specified maximum continuous reverse current; its safe operating limit is defined by total power dissipation. At 10 V Zener voltage, sustained current must remain ≤30 mA to stay within the 300 mW Ptot rating at 25 °C ambient. Derating applies above 25 °C per the 350 K/W Rth(j-a) value.
How does the marking code 'H6' correspond to BZX585-C10,115?
'H6' is the standardized top-side marking for BZX585-C10,115 per Table 4 of the datasheet. It uniquely identifies the 10 V, ±5 % variant within the C-series (2.4 V–75 V), distinguishing it from the ±2 % B-series (marked 'E6' for BZX585-B10).
Can BZX585-C10,115 be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing spread in VZ, causing current hogging when paralleled. Even matched units risk thermal runaway due to positive temperature coefficient above ~5 V. For higher power, use a single higher-rated Zener or active regulation instead.
What is the significance of the '115' suffix in BZX585-C10,115?
The '115' denotes the specific packaging and reel configuration: tape-and-reel packaging per JEDEC standard J-STD-020, 10,000 units per reel, with moisture sensitivity level (MSL) 1 - indicating unlimited floor life at ≤30 °C/85 % RH and no bake requirement prior to reflow soldering.
