For engineers reviewing the BZX84-C62/LF1R datasheet, BZX84-C62/LF1R pinout, BZX84-C62/LF1R application, or BZX84-C62/LF1R equivalent, this page delivers verified electrical parameters, thermal limits, SOT23 terminal mapping, automotive-grade reliability data, and real-world regulation use cases - all confirmed against NXP's Rev. 6 (2014) product data sheet.
Technical Context
This discrete Zener diode operates in reverse-bias breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its design supports low-power regulation with 250 mW total power dissipation at 25 °C ambient and non-repetitive peak reverse power handling up to 40 W for ≤100 µs pulses.
It features a temperature coefficient of +0.05 mV/K at 2 mA, low junction-to-ambient thermal resistance (500 K/W), and is characterized for operation across −65 °C to +150 °C junction temperature range - meeting AEC-Q101 stress test requirements for automotive electronics.
Key Specifications

FAQ
What is the exact Zener voltage tolerance for BZX84-C62/LF1R?
The BZX84-C62/LF1R has a nominal Zener voltage of 62 V with a ±5 % tolerance, meaning its actual breakdown voltage falls between 58.0 V and 66.0 V when tested at 2 mA. This tolerance is explicitly defined in Table 9 of NXP's BZX84_SER Rev. 6 datasheet and applies across the full operating temperature range.
Is BZX84-C62/LF1R suitable for automotive applications?
Yes, BZX84-C62/LF1R is AEC-Q101 qualified per Section 8.1 of the NXP datasheet, confirming its reliability for automotive use including engine control, body electronics, and ADAS subsystems. It meets stress test requirements for temperature cycling, humidity, and mechanical shock without derating.
What is the maximum continuous power dissipation for BZX84-C62/LF1R?
BZX84-C62/LF1R has a total power dissipation limit of 250 mW at ambient temperatures ≤25 °C, as specified in Table 5 (Limiting Values) of the NXP datasheet. Derating is required above 25 °C at 2.0 mW/°C based on Rth(j-a) = 500 K/W.
Does BZX84-C62/LF1R have a connected pin 2?
No, pin 2 of BZX84-C62/LF1R is internally not connected (n.c.), as confirmed in Table 2 (Pinning) of the NXP datasheet. It must remain unconnected on the PCB - no trace, pad, or solder joint should be applied to this terminal.
What is the reverse leakage current specification for BZX84-C62/LF1R?
BZX84-C62/LF1R exhibits a maximum reverse current (IR) of 80 µA at VR = 47.6 V, per Table 9 in the NXP datasheet. This value is measured at Tj = 25 °C and defines the diode's off-state leakage behavior in regulation and clamping applications.
