Product details
Overview
BZT52-C5V6X from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 5.6 V nominal regulation at 5 mA, with 400 Ω max differential resistance and 1 μA reverse current at 3.5 V, used for low-power voltage reference and overvoltage clamping in consumer power rails.
For engineers reviewing the BZT52-C5V6X datasheet, BZT52-C5V6X pinout, BZT52-C5V6X application, or BZT52-C5V6X equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (210 K/W junction-to-solder point), peak pulse power (40 W), cathode-anode polarity marking, and SOD123 footprint compatibility with IPC-7351B reflow land patterns.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its 5.6 V nominal Zener voltage is specified at IZ = 5 mA with a temperature coefficient of −2.0 to +2.5 mV/K, indicating moderate thermal drift in mid-range voltage Zeners.
The device features low differential resistance (≤400 Ω) and low capacitance (≤300 pF at 1 MHz, 0 V), enabling effective noise suppression and fast transient response in biasing and protection circuits. It is rated for 590 mW total power dissipation on a 1 cm² cathode pad and supports non-repetitive 100 μs surges up to 40 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.2 V to 6.0 V at IZ = 5 mA - defines regulation window for precision biasing in 5 V systems |
| Differential Resistance rdif | ≤400 Ω - ensures minimal output voltage shift under load current variation |
| Reverse Current IR | ≤1 μA at VR = 3.5 V - guarantees low leakage in standby or high-impedance sensing nodes |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - enables use as low-drop clamp or polarity indicator in dual-rail designs |
| Thermal Resistance Rth(j-sp) | 210 K/W - quantifies junction-to-solder-point heat transfer efficiency for PCB thermal design |
| Non-repetitive Peak Power | 40 W at tp = 100 μs - supports ESD and surge immunity in I/O protection circuits |
| Package | SOD123 - surface-mount plastic package with 2.80 mm × 1.70 mm footprint and cathode-marked band |
Pinout & Package
SOD123 package: 2-terminal surface-mount plastic case with cathode marked by a visible band; dimensions 2.80 mm × 1.70 mm × 1.30 mm (L × W × H), 0.70 mm lead pitch, 0.25 mm lead thickness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking band identifies this terminal; carries reverse-bias current during regulation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path; must be routed with low-inductance trace for transient response |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., LED bias or microcontroller reset threshold setting |
| Low 400 Ω differential resistance | Maintains <±25 mV output deviation across 62.5 μA load change, supporting stable feedback in low-current analog stages |
| 1 cm² cathode thermal pad support | Enables 590 mW continuous dissipation without derating - critical for space-constrained DC-DC converter feedback networks |
| 300 pF capacitance at 0 V | Minimizes high-frequency loading on signal lines when used in RF detector bias or clock line clamping |
| Marked cathode band | Eliminates orientation errors during automated placement; aligns with IPC-A-610 Class 2 polarity verification requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5232BS | Same 5.6 V nominal, ±5 % tolerance, but SOT-23 package (higher thermal resistance: 300 K/W vs 210 K/W) | Less effective in high-duty-cycle regulation due to lower power handling (350 mW vs 590 mW) | Prefer when board space is constrained and thermal load is <150 mW |
| Vishay BZX84-C5V6 | Identical 5.6 V/±5 % spec, but SOT-23 package and higher typical differential resistance (500 Ω vs 400 Ω) | Higher output impedance reduces regulation stability in variable-load sensor interfaces | Acceptable for static biasing where load current variation <10 μA |
Compared with MMBZ5232BS and BZX84-C5V6, BZT52-C5V6X offers superior thermal performance and lower dynamic impedance in SOD123, making it preferred for continuous-duty regulation and ESD clamping where PCB real estate permits its slightly larger footprint.

FAQ
What is the maximum continuous power dissipation for BZT52-C5V6X?
The BZT52-C5V6X has a total power dissipation rating of 590 mW when mounted on an FR4 PCB with a 1 cm² cathode thermal pad at Tamb ≤ 25 °C. Derating is required above 25 °C ambient per the thermal resistance of 210 K/W to solder point; at 70 °C ambient, maximum continuous power drops to approximately 350 mW.
How does the cathode marking appear on the SOD123 package?
The cathode is identified by a distinct band printed on the body of the SOD123 package, aligned with Pin 1 as shown in Figure 11 of the datasheet. This band corresponds to the cathode terminal (K), which must be connected to the higher-potential node during Zener operation; incorrect orientation results in forward conduction instead of regulation.
Can BZT52-C5V6X be used in automotive applications?
No - BZT52-C5V6X is explicitly designated as non-automotive qualified per Nexperia's revision history (v.2, October 2025). It lacks AEC-Q200 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia recommends the -Q qualified variants such as BZT52-C5V6-Q.
What is the typical reverse leakage current at 3.5 V?
At VR = 3.5 V and Tj = 25 °C, the reverse current IR is guaranteed ≤1 μA. This low leakage supports energy-efficient operation in always-on monitoring circuits, such as brown-out detectors or battery voltage supervisors, where standby current must remain below 10 μA.
