Product details
Overview
BZX84-C5V6/LF1VL from NXP Semiconductors is a ±5 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 5.6 V nominal breakdown voltage at 5 mA, 250 mW total power dissipation, and AEC-Q101 qualified for automotive use.
For engineers reviewing the BZX84-C5V6/LF1VL datasheet, BZX84-C5V6/LF1VL pinout, BZX84-C5V6/LF1VL application, or BZX84-C5V6/LF1VL equivalent, this page delivers verified specifications, validated pin functions, confirmed automotive-grade reliability, and real-world regulation use cases - all grounded in NXP's Rev. 6 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 targets low-power regulation where precision is secondary to cost-effective voltage clamping and overvoltage protection.
It features a typical differential resistance of 80 Ω at IZ = 5 mA, reverse current ≤1 μA at VR = 4.0 V, and a positive temperature coefficient of +1.2 mV/K - enabling predictable drift behavior in ambient-temperature-stable circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 5.2 V to 6.0 V at IZ = 5 mA - defines usable regulation window for 5.6 V nominal reference |
| 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 - ensures low-loss conduction when used in polarity-sensitive protection paths |
| Non-repetitive Peak Reverse Power | 40 W for tp ≤ 100 μs - supports transient surge suppression in ESD or load-dump scenarios |
| Temperature Coefficient SZ | +1.2 mV/K - quantifies voltage drift per degree Celsius rise, enabling thermal error budgeting |
| Reverse Current IR | ≤ 1 μA at VR = 4.0 V - confirms low leakage below knee voltage, critical for standby power integrity |
| Junction-to-Ambient Rth(j-a) | 500 K/W - determines thermal rise under steady-state bias; requires layout derating above 25 °C ambient |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mounted package with 3 leads; 2.8 mm × 1.4 mm footprint; 0.95 mm height; tin-plated terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential side in reverse-bias regulation; forward conduction path during fault conditions |
| 2 | Not Connected (n.c.) | Internal die pad with no electrical connection; must remain unconnected on PCB to avoid parasitic coupling |
| 3 | Cathode (K) | Connected to higher-potential side; defines regulated output node when used as shunt reference |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F (Diodes Inc.) | Same 5.6 V nominal, ±5 % tolerance, SOT23 package; 200 mW Ptot; higher IR (5 μA @ 4 V) | Lower power rating limits sustained regulation duty cycle; higher leakage reduces battery-life-critical low-IQ designs | Select when footprint compatibility is mandatory but thermal margin allows 200 mW derating |
| BZX84-B5V6 (NXP) | Same 5.6 V nominal, tighter ±2 % tolerance; identical package, Ptot, and surge rating | Improved voltage accuracy enables tighter feedback loops in precision references; same thermal profile | Choose for enhanced regulation stability where ±2 % tolerance justifies minor cost increase over ±5 % variant |
Compared with MMBZ5232BS-7-F, BZX84-C5V6/LF1VL offers 25 % higher continuous power handling and lower leakage, making it preferable for industrial regulators; versus BZX84-B5V6, it trades 3 % tolerance bandwidth for cost reduction in non-critical biasing roles.

FAQ
What is the exact breakdown voltage range for BZX84-C5V6/LF1VL?
The BZX84-C5V6/LF1VL has a guaranteed breakdown voltage range of 5.2 V to 6.0 V at test current IZ = 5 mA, reflecting its ±5 % tolerance grade. This range is specified in Table 8 of NXP's BZX84_SER Rev. 6 datasheet and applies under Tj = 25 °C conditions. The device maintains regulation within this band across its rated current range, making BZX84-C5V6/LF1VL suitable for applications where tight voltage tolerance is not required but stable clamping is essential.
Is BZX84-C5V6/LF1VL suitable for automotive applications?
Yes, BZX84-C5V6/LF1VL is AEC-Q101 qualified per Section 8.1 of the official datasheet, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment power domains. Its construction, testing, and thermal performance (Tj = −65 °C to +150 °C, Tstg = −55 °C to +150 °C) meet automotive reliability requirements. BZX84-C5V6/LF1VL is explicitly designated for such use, not merely "suitable" - a distinction confirmed in NXP's qualification statement.
What is the maximum reverse current at 4.0 V for BZX84-C5V6/LF1VL?
The maximum reverse current IR for BZX84-C5V6/LF1VL is 1 μA at VR = 4.0 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This low leakage ensures minimal quiescent current draw in standby or battery-backed circuits. Exceeding 4.0 V initiates measurable conduction, with knee behavior clearly defined in Figure 5. This value directly impacts BZX84-C5V6/LF1VL's effectiveness in low-power reset and bias networks.
Does BZX84-C5V6/LF1VL have a connected pin 2?
No, pin 2 of BZX84-C5V6/LF1VL is internally not connected (n.c.), as confirmed in Table 2 (Pinning) of the datasheet. It serves only as a mechanical support pad with no electrical function. PCB layout must leave pin 2 unconnected - routing traces or soldering to it may introduce parasitic capacitance or unintended coupling. This isolation is consistent across all BZX84 series SOT23 variants, and applies identically to BZX84-C5V6/LF1VL.
What is the thermal resistance from junction to ambient for BZX84-C5V6/LF1VL?
The junction-to-ambient thermal resistance Rth(j-a) for BZX84-C5V6/LF1VL is 500 K/W under free-air conditions on a standard FR4 PCB with single-sided copper and tin plating (Table 6). This value assumes no heatsinking or airflow and governs temperature rise: at 250 mW dissipation, junction temperature rises ~125 °C above ambient. Layout optimization - such as increased copper area on pin 1 and 3 - can improve actual thermal performance beyond this baseline rating for BZX84-C5V6/LF1VL.
