Product details
Overview
BZT52C5V6Q-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount Zener diode with a nominal zener voltage of 5.6 V, ±5% tolerance (5.2–6.0 V), 500 mW power dissipation at TL = +75°C, and 40 Ω maximum zener impedance at 5 mA test current - used for precision voltage regulation and overvoltage protection in automotive power supply rails.
For engineers reviewing the BZT52C5V6Q-7-F datasheet, BZT52C5V6Q-7-F pinout, BZT52C5V6Q-7-F application, or BZT52C5V6Q-7-F equivalent, key selection criteria include zener voltage stability across temperature (−2 mV/°C coefficient), low leakage (≤2.5 µA at 4.5 V), SOD123 package compatibility with automated assembly, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This Zener diode operates in reverse breakdown mode to clamp or regulate voltage at its specified nominal value under controlled current conditions. It exhibits a −2 mV/°C temperature coefficient near 5.6 V, enabling predictable drift compensation in bias networks and reference circuits.
The device delivers stable regulation from 1.0 mA to 20 mA zener current, with 40 Ω dynamic impedance at 5 mA and <100 pF total capacitance at 1 V reverse bias - supporting fast transient response and minimal signal coupling in filtering and protection applications.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5232B-TP (Micro Commercial) | Same 5.6 V nominal, but ±5% tolerance, 500 mW rating, and SOD123 package - no AEC-Q101 qualification | Lacks automotive stress testing; suitable for commercial industrial use only | Select when AEC-Q101 is not required and cost sensitivity outweighs qualification needs |
| BZX84-C5V6 (Nexperia) | 5.6 V, ±5%, 300 mW rating in SOT23 - higher thermal resistance (RθJA ≈ 375°C/W) and larger footprint | Lower power handling limits continuous regulation in high-ambient environments | Prefer only if SOT23 board layout is fixed and thermal margin >15°C exists at 75°C ambient |
Compared with MMSZ5232B-TP and BZX84-C5V6, BZT52C5V6Q-7-F uniquely combines AEC-Q101 compliance, 500 mW derated power, and SOD123 compactness - making it the only choice for automotive power rail protection where reliability and thermal headroom are jointly critical.

FAQ
What is the maximum reverse voltage this Zener can withstand before breakdown?
The BZT52C5V6Q-7-F has a nominal zener voltage of 5.6 V with a guaranteed range of 5.2–6.0 V at 5 mA test current. Breakdown occurs within this range; it is not rated for sustained reverse voltage above 6.0 V. The absolute maximum non-repetitive peak reverse voltage is not specified - operation must remain within the zener regulation region.
Does this part require external current limiting in shunt regulator configurations?
Yes - a series current-limiting resistor is mandatory. At 5.6 V output, the device draws up to 89 mA at 500 mW (P = V × I), so the resistor must set minimum current ≥1.0 mA and limit peak current to avoid exceeding 500 mW under worst-case input conditions.
How does the −2 mV/°C temperature coefficient affect circuit design?
This negative coefficient means the zener voltage decreases by approximately 2 mV per °C rise in junction temperature. In precision references, it must be compensated - e.g., by pairing with a forward-biased diode or using in temperature-stabilized enclosures - especially above 85°C ambient.
Is the SOD123 package compatible with standard reflow profiles for lead-free soldering?
Yes - the device is rated for moisture sensitivity Level 1 and qualified for JEDEC J-STD-020D reflow profiles. Its matte tin finish meets MIL-STD-202 Method 208 solderability requirements, and the UL 94V-0 molding compound withstands peak reflow temperatures up to 260°C for 10 seconds.
