Product details
Overview
BZT52C5V6-7 from Diodes Incorporated is a surface-mount 5.6 V Zener diode in SOD123 package, rated for 500 mW power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 40 Ω typical zener impedance at 5 mA test current and ±2% voltage tolerance (5.2–6.0 V). It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning and power rail stabilization circuits.
For engineers reviewing the BZT52C5V6-7 datasheet, BZT52C5V6-7 pinout, BZT52C5V6-7 application, or BZT52C5V6-7 equivalent, key selection criteria include its 5.6 V nominal zener voltage, 40 Ω dynamic impedance, 1.0 µA reverse leakage at 2.5 V, -2 mV/°C temperature coefficient, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations and supply fluctuations. Its planar die construction ensures consistent breakdown characteristics and low thermal resistance (RθJL = 150 °C/W), enabling reliable operation up to +150°C junction temperature.
The device exhibits a negative temperature coefficient of -2 mV/°C near 5.6 V, minimizing drift in mid-voltage references. Its 1.0 µA reverse current at VR = 2.5 V and 2.5 µA at VR = 5 V supports low-leakage biasing in sensor front-ends and precision comparators.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Zener Impedance (ZZT) | 40 Ω max at 5 mA - ensures minimal output voltage variation under load current changes |
| Power Dissipation (PD) | 370 mW at TA = +25°C - sets maximum continuous power in standard PCB layout without heatsinking |
| Reverse Leakage (IR) | 1.0 µA max at VR = 2.5 V - enables use in high-impedance bias networks without significant error current |
| Temperature Coefficient | -2 mV/°C - quantifies voltage drift per degree, critical for temperature-stable reference designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | Same 5.6 V nominal, but SOT-323 package (smaller footprint); 350 mW PD at TA = +25°C; 30 Ω ZZT | Preferred where board space is constrained; less thermal mass limits pulse energy handling | Select for compact consumer wearables requiring minimal PCB area |
| BZX84-C5V6 | SOT-23 package; 300 mW PD; 60 Ω ZZT; no AEC-Q101 qualification | Limited to commercial-grade applications; higher impedance increases regulation error under load | Choose only for cost-sensitive non-automotive designs with relaxed stability requirements |
Compared with MMBZ5232BS-7-F and BZX84-C5V6, BZT52C5V6-7 offers superior thermal performance (370 mW vs. 350/300 mW), automotive qualification, and lower impedance-making it optimal for industrial and automotive voltage reference roles where reliability and regulation precision are critical.

FAQ
What is the maximum reverse voltage (VR) at which BZT52C5V6-7 guarantees ≤1.0 µA leakage?
The datasheet specifies 1.0 µA maximum reverse current at VR = 2.5 V. At VR = 5 V, leakage rises to 2.5 µA. This low-leakage behavior below the zener knee supports use in high-impedance bias networks where current injection must be minimized.
Can BZT52C5V6-7 be used in place of a 5.1 V Zener for improved noise immunity?
No-its 5.6 V nominal zener voltage is not interchangeable with 5.1 V devices. While higher VZ can reduce thermal noise density, the 0.5 V difference alters circuit operating points and may violate downstream component voltage ratings. Use only where system-level design targets 5.6 V regulation.
Is the SOD123 package compatible with standard 0805 reflow profiles?
Yes-the SOD123 outline (2.65 mm × 1.55 mm × 1.05 mm) fits within IPC-7351B SOIC-123 land patterns. Its matte tin finish and Level 1 moisture sensitivity allow direct placement into standard lead-free reflow profiles without pre-baking or special handling.
Does the -7 suffix indicate tape-and-reel packaging, and what is the reel quantity?
Yes-the -7 suffix denotes 3,000-unit tape-and-reel packaging in SOD123 format. This configuration supports automated pick-and-place assembly and is the standard commercial-grade offering; automotive variants use -7-F with Q-grade qualification marking.
