Product details
Overview
BZT52C2V7LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 2.7 V, ±0.2 V tolerance (2.5–2.9 V), 5 mA test current, and 250 mW power dissipation in DFN1006-2 package; it provides precision voltage regulation and overvoltage clamping in low-power analog sensing and microcontroller I/O protection circuits.
For engineers reviewing the BZT52C2V7LP-7 datasheet, BZT52C2V7LP-7 pinout, BZT52C2V7LP-7 application, or BZT52C2V7LP-7 equivalent, key selection factors include zener voltage accuracy at 5 mA, low dynamic impedance (≤100 Ω at IZT), temperature coefficient (−3.5 to 0 mV/°C), AEC-Q101 qualification, and lead-free DFN1006-2 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its design targets low-current regulation (IZT = 5 mA) and exhibits tight voltage distribution (±0.2 V) with minimal thermal drift due to its negative temperature coefficient range of −3.5 to 0 mV/°C.
The device uses NiPdAu-plated copper leadframe terminals and green molding compound compliant with UL 94V-0, enabling reliable solderability per MIL-STD-202 Method 208 and moisture resistance rated at J-STD-020C Level 1. It is qualified to AEC-Q101 for automotive-grade reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 2.7 V nominal, 2.5–2.9 V range at 5 mA - ensures precise low-voltage reference in 3.3 V and 2.8 V rail monitoring. |
| Power Dissipation (PD) | 250 mW at TA = 25°C - supports continuous operation in space-constrained consumer and automotive modules without forced cooling. |
| Zener Impedance (ZZT) | ≤100 Ω at 5 mA - minimizes output voltage variation under dynamic load transients in sensor biasing networks. |
| Reverse Leakage (IR) | ≤20 µA at VR = 1.0 V - enables low-quiescent-current operation in battery-powered IoT node voltage supervisors. |
| Temp. Coefficient (αVZ) | −3.5 to 0 mV/°C - reduces drift-induced error in temperature-sensitive analog front-ends across −65°C to +150°C. |
| Package | DFN1006-2 (1.0 × 0.6 × 0.4 mm) - supports automated placement and reflow on fine-pitch PCBs with 0.5 mm pad pitch. |
Pinout & Package
DFN1006-2 package with two terminals: anode and cathode. Cathode identified by dot marking on top surface. No internal die bonding wire; terminals are planar metal pads on bottom side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener reference ground node | Connected to circuit common or lower-potential rail; establishes reference polarity for clamping and regulation. |
| Cathode | Reverse breakdown terminal / Zener output node | Connected to regulated node; delivers stable 2.7 V when reverse-biased above breakdown threshold. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics including body control modules and infotainment power rails. |
| Lead-free & RoHS compliant | Meets global environmental regulations without compromising solder joint integrity or thermal cycling performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5223BS-7-F | Zener voltage 2.4 V (2.2–2.6 V), same DFN1006-2 package, 200 mW PD, higher ZZT (120 Ω) | Suitable where slightly lower reference voltage is acceptable and tighter thermal stability is not required | Select when system margin allows 0.3 V lower clamping threshold and board layout already accommodates MMBZ5223BS footprint |
| BZX384-B2V7,115 | SOD-323 package (1.7 × 1.3 mm), same 2.7 V rating, 300 mW PD, but larger footprint and non-AEC-Q101 rated | Preferred for non-automotive industrial designs requiring higher power derating margin | Choose when thermal budget exceeds 250 mW or legacy SOD-323 tooling is in place and AEC-Q101 compliance is unnecessary |
Compared with MMBZ5223BS-7-F and BZX384-B2V7,115, BZT52C2V7LP-7 offers superior automotive qualification, tighter voltage tolerance, and smaller footprint-making it optimal for next-generation compact, safety-critical embedded systems where space, reliability, and precision are jointly constrained.

FAQ
What is the maximum reverse leakage current for BZT52C2V7LP-7 at 1.0 V?
The maximum reverse leakage current (IR) is 20 µA at VR = 1.0 V and TA = 25°C, measured per the datasheet's electrical characteristics table. This value remains stable up to 85°C, making it suitable for low-power always-on monitoring circuits where standby current must stay below 50 µA.
Is BZT52C2V7LP-7 compatible with standard DFN1006-2 reflow profiles?
Yes - the device is qualified for Pb-free reflow per JEDEC J-STD-020C Level 1, with peak temperature up to 260°C and time above liquidus ≤60 seconds. Its NiPdAu-plated terminals ensure robust wetting and void-free solder joints using standard SAC305 paste and Type 3 stencil apertures.
Does the cathode dot marking align with industry-standard DFN polarity conventions?
Yes - the cathode dot on the top surface corresponds to the cathode terminal (pin 2), consistent with JEDEC MO-229 and Diodes Incorporated's DFN1006-2 mechanical drawings. The anode is the unmarked terminal (pin 1), matching layout guidelines in DS30506 Rev. 16, Page 4.
Can BZT52C2V7LP-7 be used in place of a 2.5 V Zener for improved noise immunity?
No - its specified zener voltage range is 2.5–2.9 V at 5 mA; substituting for a true 2.5 V part (e.g., BZT52C2V4LP-7) would raise the clamping threshold by up to 0.4 V, potentially exceeding safe input limits of downstream logic. Always match VZ spec to system-level voltage margin requirements.
