Product details
Overview
BZT52C5V6S-7 from Diodes Incorporated is a surface-mount 5.6 V Zener diode in SOD-123 package, rated for 500 mW power dissipation, 40 Ω maximum Zener impedance at 5 mA, and 2.5 µA maximum reverse leakage at 4.5 V. It provides precise voltage regulation in low-power biasing and reference circuits, commonly used in power supply feedback loops and overvoltage protection for microcontroller I/O pins.
For engineers reviewing the BZT52C5V6S-7 datasheet, BZT52C5V6S-7 pinout, BZT52C5V6S-7 application, or BZT52C5V6S-7 equivalent, key selection criteria include nominal Zener voltage tolerance (±7.1%), thermal resistance (250 °C/W), cathode-band polarity marking, and compatibility with automated SMT assembly on ceramic PCB substrates.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 5.6 V reference across a 1–10 mA current range. Its planar die construction ensures consistent voltage regulation and low temperature coefficient (−2 mV/°C) under nominal test conditions.
The device is characterized at 5 mA test current (IZT), with 1.0 mA knee current (IZK) defining the onset of regulated conduction. Reverse leakage remains ≤2.5 µA up to 4.5 V, supporting reliable clamping in low-current sensing and analog reference paths.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V min/max - defines regulated output voltage window at 5 mA |
| Power Dissipation (Pd) | 500 mW - sets absolute max continuous power on ceramic PCB per JEDEC standard mounting |
| Zener Impedance (ZZT) | 40 Ω max at 5 mA - determines voltage deviation under dynamic load changes |
| Reverse Leakage (IR) | 2.5 µA max at 4.5 V - ensures minimal quiescent current in standby clamp configurations |
| Temperature Coefficient | −2 mV/°C - quantifies voltage drift with ambient temperature rise |
| Thermal Resistance (RθJA) | 250 °C/W - links junction temperature rise to ambient and power dissipation |
| Package | SOD-123 - standardized 2-pin surface-mount outline with cathode band marking |

Applications
| Power Supply Feedback | Microcontroller I/O Protection |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck converter feedback networks. IC Role / Device Role / Timing Role: Zener reference element in optocoupler-coupled feedback loop.

Use Scenario: Providing stable 5.6 V reference for ADC voltage dividers or comparator thresholds. IC Role / Device Role / Timing Role: Precision DC voltage source for analog front-end calibration. Use Value: Delivers <1% regulation error over −40 to +85 °C due to predictable −2 mV/°C drift. | Use Scenario: Biasing thermistor or photodiode circuits where supply current must stay below 10 µA. IC Role / Device Role / Timing Role: Low-power voltage clamp establishing sensor operating point. Use Value: Enables sub-µA standby operation while maintaining accurate 5.6 V node stability. |
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 | Same 5.6 V rating, but SOT-23 package; higher RθJA (357 °C/W); 500 mW derated to 350 mW at TA = 25 °C | Less thermal margin in dense layouts; requires larger copper area for equivalent power handling | Prefer when board space allows SOT-23 and existing footprint reuse is critical |
| BZX84-C5V6 | 5.6 V, SOT-23, 350 mW rating; 60 Ω ZZT max; −2.5 mV/°C TC; RoHS compliant | Higher impedance and wider tempco reduce regulation precision in precision references | Acceptable for non-critical clamping where cost is prioritized over voltage stability |
Compared with MMBZ5232BS-7-F and BZX84-C5V6, BZT52C5V6S-7 offers superior thermal performance (250 vs. ≥350 °C/W), tighter voltage tolerance (±7.1% vs. ±8.9%), and lower Zener impedance-making it preferred for space-constrained yet thermally demanding regulation tasks.

FAQ
What is the maximum power dissipation for BZT52C5V6S-7 under standard mounting conditions?
The BZT52C5V6S-7 is rated for 500 mW power dissipation when mounted on a ceramic PCB measuring 7.6 mm × 9.4 mm × 0.87 mm with 25 mm² pad areas. Derating begins above 25 °C ambient, following the curve in Figure 1 of DS18004 Rev. 22, reaching zero dissipation at 150 °C.
How does the cathode band marking identify polarity on the SOD-123 package?
The cathode band on the BZT52C5V6S-7 is a visible stripe located near Terminal A (anode side) of the SOD-123 body. When viewed with the marking band on the left, the right-hand terminal is the cathode - confirming correct orientation for reverse-bias operation in regulation or clamping circuits.
Is BZT52C5V6S-7 suitable for use in automotive applications?
BZT52C5V6S-7 meets AEC-Q200 stress test requirements for passive components and operates across −65 to +150 °C. While not AEC-Q101 qualified as a discrete semiconductor, its thermal robustness and RoHS compliance make it suitable for under-hood auxiliary circuits where full qualification is not mandated.
What is the typical Zener voltage tolerance at 25 °C and how is it verified?
The BZT52C5V6S-7 has a nominal Zener voltage of 5.6 V with a guaranteed range of 5.2 V to 6.0 V at 5 mA test current and 25 °C ambient. This tolerance is verified per production lot using automated parametric testing per DS18004 Rev. 22, with 100% screening for VZ and IR parameters.
