Product details
Overview
BZX84-C10/LF1VL from NXP Semiconductors is a silicon planar Zener diode in SOT23 package, designed for low-power voltage regulation with nominal 10 V breakdown voltage (±5 % tolerance), 250 mW total power dissipation, and AEC-Q101 qualification for automotive use. It operates as a shunt regulator in power supply rail stabilization and overvoltage protection circuits.
For engineers reviewing the BZX84-C10/LF1VL datasheet, BZX84-C10/LF1VL pinout, BZX84-C10/LF1VL application, or BZX84-C10/LF1VL equivalent, key selection criteria include its 10 V Zener voltage tolerance, differential resistance of 50 Ω at 5 mA, reverse current ≤0.2 μA at 7.6 V, temperature coefficient of +4.5 mV/K, and SOT23 footprint compatibility with automated assembly.
Technical Context
This Zener diode uses a silicon planar construction to achieve stable reverse-biased breakdown behavior. Its operation relies on controlled avalanche and Zener mechanisms depending on voltage range, with the BZX84-C10 variant optimized for 10 V regulation where both mechanisms contribute.
The device is characterized at Tj = 25 °C with specified parameters including forward voltage ≤0.9 V at 10 mA, non-repetitive peak reverse power dissipation up to 40 W (100 μs pulse), and thermal resistance from junction to ambient of 500 K/W in free air.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.4 V to 10.6 V at IZ = 5 mA - defines regulated output voltage range under nominal bias |
| Tolerance | ±5 % - determines worst-case regulation accuracy in production designs |
| Differential Resistance (rdiff) | 50 Ω max at IZ = 5 mA - impacts load regulation error and ripple rejection |
| Reverse Current (IR) | ≤0.2 μA at VR = 7.6 V - ensures minimal leakage in standby or low-power modes |
| Temperature Coefficient (SZ) | +4.5 mV/K typical - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - relevant for polarity-check or ESD clamp configurations |
Pinout & Package
Package: SOT23 (TO-236AB), plastic surface-mounted, 3-lead, dimensions 2.9 × 1.3 × 1.0 mm (L × W × H), standard footprint per Fig 9/10 in datasheet Rev. 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connected to lower-potential side in shunt regulation; forward conduction path when biased positively |
| 2 (n.c.) | Not connected | Internally unconnected; no electrical function; must remain floating in PCB layout |
| 3 (Cathode) | Cathode connection | Connected to higher-potential side; reverse-biased terminal during Zener operation; primary heat path to PCB |

FAQ
What is the Zener voltage tolerance of BZX84-C10/LF1VL?
The BZX84-C10/LF1VL has a nominal Zener voltage of 10 V with a tolerance of ±5 %, meaning its actual breakdown voltage falls between 9.4 V and 10.6 V when tested at 5 mA. This tolerance reflects the "C" grade within the BZX84 series and is confirmed in Table 8 of the NXP datasheet Rev. 6. The BZX84-C10/LF1VL maintains this specification across its qualified operating temperature range.
Is BZX84-C10/LF1VL suitable for automotive applications?
Yes, BZX84-C10/LF1VL is AEC-Q101 qualified per Section 8.1 of the NXP datasheet, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment systems. The BZX84-C10/LF1VL meets stress test requirements for temperature cycling, humidity, and mechanical robustness, and operates across −65 °C to +150 °C junction temperature.
What is the maximum continuous power dissipation for BZX84-C10/LF1VL?
The BZX84-C10/LF1VL has a total power dissipation limit of 250 mW at ambient temperatures ≤25 °C when mounted on a standard FR4 PCB with single-sided copper and tin plating (per Table 5 and footnote [2]). Derating is required above 25 °C ambient, following the thermal resistance Rth(j-a) = 500 K/W. The BZX84-C10/LF1VL must not exceed this limit in continuous DC operation to ensure reliability.
Does BZX84-C10/LF1VL have a connected pin 2?
No, pin 2 of the BZX84-C10/LF1VL is internally not connected (n.c.), as documented in Table 2 (Pinning) of the NXP datasheet. It serves no electrical function and must remain unconnected on the PCB. The active terminals are pin 1 (anode) and pin 3 (cathode); routing or soldering to pin 2 may cause assembly defects or measurement errors. This applies identically to all BZX84-C10/LF1VL units.
What is the reverse leakage current specification for BZX84-C10/LF1VL?
The BZX84-C10/LF1VL exhibits a maximum reverse current (IR) of 0.2 μA at VR = 7.6 V, as specified in Table 8 of the NXP datasheet. This low leakage supports energy-efficient operation in battery-backed or always-on circuits. The value is measured at Tj = 25 °C and represents worst-case behavior; actual leakage increases with temperature and applied voltage. The BZX84-C10/LF1VL maintains this spec across its full rated voltage range.
