Product details
Overview
BZX84-C13/LF1VL from NXP Semiconductors is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 13 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualified for automotive use.
For engineers reviewing the BZX84-C13/LF1VL datasheet, BZX84-C13/LF1VL pinout, BZX84-C13/LF1VL application, or BZX84-C13/LF1VL equivalent, key selection criteria include Zener voltage tolerance (±5 %), differential resistance (≤170 Ω at IZ = 5 mA), reverse current (≤0.1 μA at VR = 10.4 V), thermal resistance (500 K/W junction-to-ambient), and automotive qualification status.
Technical Context
This discrete Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. It exhibits a positive temperature coefficient of +7.0 mV/K at IZ = 5 mA and 13 V nominal regulation, with diode capacitance of 80 pF at 1 MHz and 0 V reverse bias.
Designed for low-power voltage regulation, it supports non-repetitive peak reverse power dissipation up to 40 W (tp ≤ 100 μs) and forward voltage ≤0.9 V at IF = 10 mA. Its junction temperature range spans −65 °C to +150 °C, and storage temperature extends from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.4 V to 14.1 V at IZ = 5 mA - defines usable regulation window for 13 V nominal reference |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Differential Resistance (rdif) | ≤170 Ω at IZ = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Reverse Current (IR) | ≤0.1 μA at VR = 10.4 V - ensures low leakage below breakdown threshold |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - specifies conduction loss when used in forward-biased protection paths |
| Thermal Resistance (Rth(j-a)) | 500 K/W - indicates self-heating rise per watt in free-air mounting; requires thermal design margin |
| Temperature Coefficient (SZ) | +7.0 mV/K at IZ = 5 mA - quantifies voltage drift with junction temperature change |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 2.8 mm × 1.4 mm footprint, 1.1 mm height, and standard 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connected to lower-potential node in reverse-bias configuration; carries forward current during transient clamping |
| 2 (n.c.) | Not connected | No internal bond; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress |
| 3 (Cathode) | Cathode connection | Connected to higher-potential node; defines Zener breakdown polarity and serves as primary heat path to PCB copper |
Key Features

FAQ
What is the Zener voltage tolerance for BZX84-C13/LF1VL?
The BZX84-C13/LF1VL has a nominal Zener voltage of 13 V with a tolerance of approximately ±5 %, meaning its actual breakdown voltage falls between 12.4 V and 14.1 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. The BZX84-C13/LF1VL maintains this tolerance across its qualified operating temperature range.
Is BZX84-C13/LF1VL suitable for automotive applications?
Yes, BZX84-C13/LF1VL is AEC-Q101 qualified, as explicitly stated in Section 8.1 of the NXP datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing-validating its reliability for under-hood and cabin automotive environments. BZX84-C13/LF1VL meets the requirements for use in automotive ECUs, body control modules, and infotainment power supplies.
What is the maximum non-repetitive peak reverse power dissipation for BZX84-C13/LF1VL?
The BZX84-C13/LF1VL supports a non-repetitive peak reverse power dissipation of 40 W under pulse conditions of tp ≤ 100 μs and duty cycle δ ≤ 0.02, as specified in Table 5 (Limiting Values) of the NXP datasheet. This capability enables the BZX84-C13/LF1VL to absorb short-duration transients such as load dump or ESD events without permanent degradation when properly mounted on FR4 PCB.
What is the thermal resistance from junction to ambient for BZX84-C13/LF1VL?
The thermal resistance from junction to ambient (Rth(j-a)) for BZX84-C13/LF1VL is 500 K/W under free-air conditions, per Table 6 of the NXP datasheet. This value assumes mounting on a standard FR4 PCB with single-sided copper and tin-plated finish. The BZX84-C13/LF1VL's thermal performance must be evaluated in context of actual board layout, copper area, and airflow to ensure junction temperature remains within −65 °C to +150 °C limits.
Does BZX84-C13/LF1VL have a not-connected pin, and how should it be handled on the PCB?
Yes, BZX84-C13/LF1VL has Pin 2 designated as "n.c." (not connected), as shown in Table 2 (Pinning) of the NXP datasheet. This terminal has no internal bond wire or silicon connection. On the PCB, Pin 2 must remain unconnected-no trace, pad, or via should be routed to it-to prevent mechanical stress, parasitic coupling, or unintended current paths that could compromise reliability or regulation performance of the BZX84-C13/LF1VL.
