Product details
Overview
BZT52C7V5Q-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount Zener diode with nominal 7.5 V zener voltage, 5 mA test current, 15 Ω maximum zener impedance at IZT, and 500 mW power dissipation in SOD123 package. It provides precise voltage regulation in automotive power supply monitoring and ECU reference circuits.
For engineers reviewing the BZT52C7V5Q-7-F datasheet, BZT52C7V5Q-7-F pinout, BZT52C7V5Q-7-F application, or BZT52C7V5Q-7-F equivalent, this page delivers verified electrical parameters, automotive-grade qualification status, thermal derating behavior, and validated alternatives for board-level voltage clamping and reference design.
Technical Context
This Zener diode operates in reverse breakdown mode with a tightly controlled 7.0–7.9 V zener voltage range at 5 mA test current and exhibits low dynamic impedance (15 Ω max) for stable regulation under varying load conditions. Its −2.5 to +5.3 mV/°C temperature coefficient ensures predictable drift across −65°C to +150°C operating range.
The device uses planar die construction in a molded plastic SOD123 case with matte tin-plated alloy 42 leadframe, rated for 370 mW at 25°C ambient and derated to 500 mW at 75°C lead temperature. Polarity is marked by cathode band; moisture sensitivity level is 1 per J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5236B-TP (Micro Commercial) | 7.5 V nominal, 100 Ω ZZT max at 20 mA, SOD123, no AEC-Q101 rating | Commercial-grade only; unsuitable for automotive under-hood environments | Select when cost sensitivity outweighs automotive qualification and tighter impedance is not required |
| BZX84-C7V5 (Nexperia) | 7.5 V nominal, 30 Ω ZZT max at 5 mA, SOT23, AEC-Q101 qualified | Different footprint (SOT23 vs SOD123); requires PCB redesign and requalification | Choose for space-constrained layouts where 2.9 × 1.3 mm SOT23 fits better than 2.85 × 1.7 mm SOD123 |
Compared with MMSZ5236B-TP and BZX84-C7V5, BZT52C7V5Q-7-F offers superior impedance (15 Ω vs 100/30 Ω) and automotive-grade reliability in a widely adopted SOD123 footprint-making it optimal for high-stability, production-critical voltage references where thermal robustness and qualification are mandatory.

FAQ
What is the maximum reverse current for BZT52C7V5Q-7-F at 5.3 V?
The maximum reverse current (IR) is 5 µA at VR = 5.3 V, measured at 25°C ambient. This low leakage supports high-impedance bias networks and minimizes power loss in always-on reference circuits used in battery-powered systems.
Is BZT52C7V5Q-7-F suitable for reflow soldering without pre-baking?
Yes. With Moisture Sensitivity Level 1 per J-STD-020, BZT52C7V5Q-7-F may be mounted directly after unpacking using standard lead-free reflow profiles (peak 260°C), eliminating bake steps and reducing assembly cycle time.
How does the temperature coefficient affect regulation accuracy over −40°C to +125°C?
With a temperature coefficient ranging from −2.5 to +5.3 mV/°C, the zener voltage drift is bounded to approximately ±0.8 V over the full range-enabling stable 7.5 V reference performance in automotive cabin and under-hood applications.
Can BZT52C7V5Q-7-F replace BZT52C7V5-7-F in existing designs?
Yes-BZT52C7V5Q-7-F is the automotive-qualified version of BZT52C7V5-7-F, sharing identical electrical specs and SOD123 packaging. The "Q" suffix denotes AEC-Q101 qualification; no layout or schematic changes are needed for drop-in replacement in automotive designs.
