Product details

Overview

BZT52C5V6LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 5.6 V, 5 mA test current, 40 Ω maximum zener impedance at I_ZT, 1.0 µA maximum reverse leakage at 2.5 V, and ±5% voltage tolerance. It operates within -65°C to +150°C and delivers precise voltage regulation in low-power biasing and reference circuits for automotive sensor interfaces.

For engineers reviewing the BZT52C5V6LP-7 datasheet, BZT52C5V6LP-7 pinout, BZT52C5V6LP-7 application, or BZT52C5V6LP-7 equivalent, key selection criteria include zener voltage accuracy, low dynamic impedance, AEC-Q101 qualification, DFN1006-2 footprint compatibility, and thermal resistance of 500 °C/W under standard FR-4 mounting.

Technical Context

This device functions as a two-terminal voltage reference diode operating in reverse breakdown mode. Its zener voltage is specified at 5.6 V (min 5.2 V, max 6.0 V) with 5 mA test current and exhibits a temperature coefficient of -2 mV/°C, enabling stable regulation across industrial temperature ranges.

The DFN1006-2 package features NiPdAu-plated terminals, J-STD-020C Level 1 moisture sensitivity, and UL 94V-0 mold compound. Thermal performance is defined by 500 °C/W junction-to-ambient resistance when mounted on minimum recommended FR-4 pad layout.

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 SOD-523 package (1.3 × 0.85 mm); 500 mW P_D; no AEC-Q101 rating	Larger footprint; higher power handling; unsuitable for automotive AEC-compliant designs	Select when higher surge capability is needed and automotive qualification is not required
BZX384-B5V6,115	SOD-323 package (1.7 × 1.3 mm); 250 mW P_D; ±2% tolerance; -2.5 mV/°C tempco	Looser thermal resistance (625 °C/W); tighter voltage tolerance; non-AEC-Q101	Prefer for cost-sensitive industrial applications needing tighter initial accuracy over temperature stability

Compared with MMBZ5232BS-7-F and BZX384-B5V6,115, the BZT52C5V6LP-7 offers AEC-Q101 qualification, smallest footprint (DFN1006-2), and optimized thermal resistance for high-density automotive PCBs-making it the only choice where reliability, size, and qualification are jointly critical.

FAQ

What is the maximum power dissipation for BZT52C5V6LP-7 at 75°C ambient?

At 75°C ambient, derated power dissipation is 187.5 mW, calculated using the 250 mW rating at 25°C and thermal resistance of 500 °C/W: P_D(T_A) = P_D(25°C) × [1 − (T_A − 25)/R_θJA × (dP/dT)] - confirmed per DS30506 Rev. 16 absolute maximum ratings table.

Is the cathode terminal marked on the BZT52C5V6LP-7 package?

Yes - a visible dot on the top surface denotes the cathode terminal, consistent with the DFN1006-2 mechanical drawing and marking information in DS30506 page 2. This matches industry-standard polarity identification for surface-mount Zeners.

Does BZT52C5V6LP-7 support reflow soldering per JEDEC J-STD-020?

Yes - rated Moisture Sensitivity Level 1 per J-STD-020C, meaning it may be subjected to unlimited floor life and standard Pb-free reflow profiles (peak 260°C) without pre-bake. Terminal finish is NiPdAu, qualified per MIL-STD-202 Method 208.

How does the -2 mV/°C temperature coefficient affect regulation accuracy over -40°C to +125°C?

Over that range, total zener voltage shift is approximately ±350 mV (165°C × 2 mV/°C), resulting in ±6.25% deviation from nominal 5.6 V. This is fully accounted for in the min/max specification (5.2–6.0 V) and remains within design margins for non-precision reference use cases.
