Product details
Overview
BZX84-C16/LF1VL from NXP Semiconductors is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 16 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualified for automotive use.
For engineers reviewing the BZX84-C16/LF1VL datasheet, BZX84-C16/LF1VL pinout, BZX84-C16/LF1VL application, or BZX84-C16/LF1VL equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (≤75 Ω at IZ = 5 mA), reverse current (≤0.05 μA at VR = 12.8 V), thermal resistance (500 K/W junction-to-ambient), and automotive qualification status.
Technical Context
This discrete Zener diode operates in reverse-bias breakdown mode to maintain stable reference voltage under varying load and temperature conditions. It delivers precise regulation with a temperature coefficient of +10.4 mV/K (typical) and low dynamic impedance (75 Ω max at 5 mA).
Designed for surface-mount applications on FR4 PCBs with single-sided copper, it supports non-repetitive peak reverse power dissipation up to 40 W (tp ≤ 100 μs) and continuous operation up to 150 °C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V min / 17.1 V max at IZ = 5 mA - defines regulation window for stable 16 V reference |
| Differential Resistance (rdif) | ≤75 Ω at IZ = 5 mA - ensures low output impedance for tight voltage control |
| Reverse Current (IR) | ≤0.05 μA at VR = 12.8 V - guarantees minimal leakage below breakdown threshold |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB |
| Thermal Resistance (Rth(j-a)) | 500 K/W - determines junction temperature rise per watt in free-air mounting |
| Non-repetitive Peak Reverse Power | 40 W (tp ≤ 100 μs) - enables transient overvoltage clamping without damage |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling and humidity testing |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 2.8 mm × 1.4 mm footprint; 1.1 mm height; tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |

| 1 | Anode (A) | Forward-bias connection point; reverse-biased during Zener operation |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical bond - must remain unconnected on PCB |
| 3 | Cathode (K) | Reference node for regulated voltage; connected to circuit ground or return path |
Key Features

FAQ
What is the Zener voltage tolerance of BZX84-C16/LF1VL?
The BZX84-C16/LF1VL has a nominal Zener voltage of 16 V with a tolerance of approximately ±5 %, meaning its actual breakdown voltage falls between 15.3 V and 17.1 V when tested at 5 mA. This tolerance band is defined per the BZX84-C series specification and confirmed in Table 8 of the NXP datasheet Rev. 6.
Is BZX84-C16/LF1VL qualified for automotive applications?
Yes, BZX84-C16/LF1VL is AEC-Q101 qualified, as explicitly stated in Section 8.1 of the NXP datasheet. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock, validating its use in automotive body electronics, infotainment systems, and engine control units.
What is the maximum continuous power dissipation for BZX84-C16/LF1VL?
BZX84-C16/LF1VL has a total power dissipation rating of 250 mW at ambient temperatures ≤25 °C, as specified in Table 1 (Quick reference data) and Table 5 (Limiting values). Derating is required above 25 °C per the thermal resistance value of 500 K/W.
Does BZX84-C16/LF1VL have a connected pin 2?
No, pin 2 of BZX84-C16/LF1VL is internally not connected (n.c.), as documented in Table 2 (Pinning) of the datasheet. This terminal must remain unconnected on the PCB layout to avoid unintended parasitic paths or solder bridging issues.
What is the typical temperature coefficient of BZX84-C16/LF1VL?
The typical temperature coefficient of BZX84-C16/LF1VL is +10.4 mV/K, as listed in Table 8 under "Temperature coefficient SZ (mV/K)" for the C16 variant. This positive coefficient indicates that the Zener voltage increases by ~10.4 mV per degree Celsius rise in junction temperature.
