Product details
Overview
BZT52C7V5LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 7.5 V (min 7.0 V, max 7.9 V at 5 mA), 250 mW power dissipation, 15 Ω zener impedance at 5 mA, and AEC-Q101 qualification for automotive reliability. It operates from −65 °C to +150 °C and is used for precision voltage regulation in low-power sensor biasing circuits.
For engineers reviewing the BZT52C7V5LP-7 datasheet, BZT52C7V5LP-7 pinout, BZT52C7V5LP-7 application, or BZT52C7V5LP-7 equivalent, key selection criteria include zener voltage tolerance (±6.7%), low dynamic impedance (15 Ω), cathode-marked DFN1006-2 package, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This device functions as a two-terminal voltage reference diode operating in reverse breakdown. Its zener voltage exhibits a positive temperature coefficient of +2.5 mV/°C at 5 mA test current, enabling stable regulation across industrial temperature ranges.
Designed for low-current stabilization, it delivers 1.0 µA maximum reverse leakage at VR = 5.0 V and supports 5.3 mA maximum zener current before thermal derating begins - consistent with its 250 mW PD rating on FR-4 PCB with minimum pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.5 V nominal (7.0–7.9 V range at 5 mA); enables precise 7.5 V rail clamping or reference generation |
| Power Dissipation (PD) | 250 mW at TA = 25 °C; limits continuous zener current to ~33 mA at 7.5 V without heatsinking |
| Zener Impedance (ZZT) | 15 Ω at IZT = 5 mA; ensures <1% output variation for ±1 mA load shifts |
| Reverse Leakage (IR) | 1.0 µA max at VR = 5.0 V; minimizes quiescent current in battery-powered voltage monitors |
| Temp Coefficient (αVZ) | +2.5 mV/°C at IZTC = 5 mA; provides predictable drift for temperature-compensated references |
| Package | DFN1006-2 (1.0 × 0.6 × 0.5 mm); enables high-density placement in space-constrained automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5235B-7-F | Zener voltage 7.5 V (±5%), 500 mW PD, SOD-123 package (2.7 × 1.6 mm) | Larger footprint; higher power handling but lower density | Preferred where board space allows and higher surge capability is needed |

FAQ
What is the maximum reverse leakage current for BZT52C7V5LP-7 at 5.0 V?
The maximum reverse leakage current (IR) is 1.0 µA at VR = 5.0 V and TA = 25 °C, as specified in the Electrical Characteristics table. This value remains ≤2.0 µA across the full −65 °C to +150 °C operating range per Diodes Inc. characterization data.
Is BZT52C7V5LP-7 compatible with lead-free reflow profiles?
Yes - BZT52C7V5LP-7 is RoHS-compliant and rated for standard JEDEC J-STD-020C lead-free reflow, with peak temperature up to 260 °C. Its NiPdAu-plated terminals and UL 94V-0 molding compound ensure reliable wetting and mechanical integrity under IPC-A-610 Class 2/3 conditions.
How does the +2.5 mV/°C temperature coefficient affect circuit design?
The positive temperature coefficient means VZ increases linearly with junction temperature. At 100 °C ambient (assuming ~25 °C rise), VZ rises by ~25 mV - a +0.33% shift from nominal 7.5 V. Designers compensate by pairing with negative-TC components or using trimming in precision references.
Can BZT52C7V5LP-7 be used in place of a 7.5 V TL431 shunt regulator?
No - BZT52C7V5LP-7 is a passive two-terminal Zener diode without adjustable feedback or current-sink capability. Unlike the TL431, it cannot regulate dynamically or drive loads >5 mA without significant voltage deviation due to ZZT = 15 Ω. It serves only as fixed-voltage clamp or reference, not active regulation.
