Product details
Overview
BZT52C5V6SQ-7-F from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 5.6 V, 5 mA test current, 40 Ω maximum zener impedance at 5 mA, 200 mW power dissipation, and SOD323 package. It provides precise voltage regulation in low-power analog reference and overvoltage protection circuits for automotive body control modules.
For engineers reviewing the BZT52C5V6SQ-7-F datasheet, BZT52C5V6SQ-7-F pinout, BZT52C5V6SQ-7-F application, or BZT52C5V6SQ-7-F equivalent, key selection criteria include zener voltage tolerance (±7.1%), temperature coefficient (−2.0 mV/°C), reverse leakage (3 µA at 2.0 V), and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load or supply conditions. Its planar die construction ensures consistent breakdown characteristics, while the SOD323 package supports high-density PCB layouts and automated reflow assembly.
The device exhibits a negative temperature coefficient of −2.0 mV/°C, meaning its zener voltage decreases slightly as junction temperature rises. At 5 mA test current, it delivers 5.6 V ±0.4 V (min 5.2 V, max 6.0 V) with low dynamic impedance (40 Ω), enabling accurate voltage clamping in feedback networks and reference dividers.
Key Specifications

| Zener Impedance (ZZT) | 40 Ω max at f = 1 kHz, IZT = 5 mA - determines regulation stiffness under dynamic load changes |
| Reverse Leakage (IR) | 3 µA max at VR = 2.0 V - ensures minimal quiescent current in standby voltage references |
| Temperature Coefficient | −2.0 mV/°C - quantifies voltage drift per degree rise, critical for thermal stability in automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5232BS-7-F | Zener voltage 5.6 V (same), but 500 mW PD, SOD123 package, no AEC-Q101 qualification | Higher power handling; unsuitable for automotive due to lack of stress testing | Select only for non-automotive, higher-current reference needs where board space allows larger SOD123 footprint |
| BZX84-C5V6 | Zener voltage 5.6 V (same), 350 mW PD, SOT23 package, AEC-Q101 qualified | Larger footprint (2.9 mm × 1.3 mm), higher thermal resistance (RθJA = 350°C/W vs. 625°C/W) | Prefer when higher surge capability is required and PCB layout accommodates SOT23; verify thermal derating at 125°C ambient |
Compared with MMSZ5232BS-7-F and BZX84-C5V6, BZT52C5V6SQ-7-F offers optimal balance of automotive qualification, ultra-compact SOD323 size, and low-impedance regulation-making it preferred for space-constrained, thermally demanding automotive modules where strict qualification is mandatory.

FAQ
What is the maximum reverse leakage current for BZT52C5V6SQ-7-F at 2.0 V?
The maximum reverse leakage current is 3 µA at VR = 2.0 V and TA = 25°C, as specified in the Electrical Characteristics table. This value remains ≤5 µA up to 85°C ambient, verified per AEC-Q101 thermal testing protocols.
Is BZT52C5V6SQ-7-F suitable for use in a 12 V automotive battery monitoring circuit?
Yes - its 5.6 V zener voltage enables robust voltage division from 12 V systems using standard resistor ratios. The AEC-Q101 qualification, −40°C to +150°C operating range, and low temperature coefficient ensure reliable performance across automotive battery voltage transients (6–16 V).
How does the SOD323 package affect thermal performance compared to SOD123?
The SOD323 package has higher thermal resistance (RθJA = 625°C/W) than SOD123 (≈300°C/W), limiting continuous power dissipation to 200 mW at 25°C ambient. Derating is required above 25°C: at 85°C ambient, max power drops to ~120 mW per the published derating curve.
Can BZT52C5V6SQ-7-F replace BZT52C5V1S in a 5 V reference design?
No - BZT52C5V1S has a nominal zener voltage of 5.1 V (4.8–5.4 V range), while BZT52C5V6SQ-7-F is 5.6 V (5.2–6.0 V). Substituting would shift reference voltage by +0.5 V, potentially violating ADC input range or comparator thresholds; redesign of scaling resistors is required.
