Product details
Overview
BZT52C36LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 36 V, ±5.6% tolerance (34.0–38.0 V), 2 mA test current, 90 Ω maximum zener impedance at test current, and 250 mW power dissipation - used for precision voltage regulation and overvoltage protection in compact DC power rails.
For engineers reviewing the BZT52C36LP-7 datasheet, BZT52C36LP-7 pinout, BZT52C36LP-7 application, or BZT52C36LP-7 equivalent, key selection criteria include zener voltage stability at low test current (2 mA), thermal resistance (500 °C/W), cathode-marked DFN1006-2 package compatibility with high-density PCB layouts, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to clamp voltage at its specified zener voltage when reverse-biased above VZ. It exhibits a positive temperature coefficient of +36.5 to +45.5 mV/°C at 5 mA, enabling predictable drift compensation in temperature-sensitive circuits.
Designed for low-power regulation, it delivers stable clamping under 0.5 mA minimum knee current and supports up to 0.1 µA reverse leakage at 25.2 V - critical for battery-backed monitoring and low-quiescent circuits where leakage-induced discharge must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V nominal, 34.0–38.0 V range at 2 mA - defines precise clamping threshold for 3.3 V/5 V rail supervisors and ADC reference buffers |
| Power Dissipation (PD) | 250 mW at TA = 25°C - limits continuous dissipation without heatsinking on standard FR-4 PCBs |
| Zener Impedance (ZZT) | 90 Ω max at IZT = 2 mA - determines voltage regulation stiffness under dynamic load transients |
| Reverse Leakage (IR) | 0.1 µA max at VR = 25.2 V - ensures minimal standby current in always-on sensor nodes |
| Thermal Resistance (RθJA) | 500 °C/W - sets junction-to-ambient rise per watt; requires careful pad layout to avoid thermal derating |
| Temp. Coefficient (αVZ) | +36.5 to +45.5 mV/°C at IZTC = 5 mA - enables linear temperature compensation in analog front-ends |
| Package | DFN1006-2 (1.0 × 0.6 × 0.5 mm) - ultra-compact footprint for space-constrained wearables and IoT modules |
Pinout & Package
DFN1006-2 package: 2-terminal surface-mount device with cathode marked by dot on top surface; terminals are anode (pin 1) and cathode (pin 2); no internal die bonding wires - monolithic silicon structure with NiPdAu-plated copper leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / reference ground node | Connected to system ground or lower-potential rail; forms return path during forward bias or zener regulation |
| Cathode | Reverse breakdown terminal / regulated output node | Marked with dot; connected to voltage node requiring clamping; carries reverse current during overvoltage events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics - meets stress testing for temperature cycling, HTRB, and ESD |
| Lead-free & RoHS compliant | No intentionally added lead; UL 94V-0 molding compound - satisfies global environmental compliance and solder reflow requirements |
| Moisture Sensitivity Level 1 | Unlimited floor life at ≤30°C/60% RH - eliminates baking requirement before SMT assembly |
| Ultra-small DFN1006-2 | 0.001 g weight, 0.6 mm width - enables placement in <1.0 mm pitch layouts for miniaturized medical sensors and hearing aids |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5267BLT1G | Zener voltage 36 V, but rated at 3 mA test current; higher ZZT (100 Ω vs. 90 Ω); SOT-23 package (larger footprint) | Less suitable for ultra-dense layouts; higher thermal resistance (625 °C/W) reduces power handling on small pads | Select if existing SOT-23 footprint reuse is required and board area permits larger package |
| BZX84-C36 | Same 36 V rating, but SOT-23-3L package with cathode/anode/NC pins; 500 mW PD; not AEC-Q101 qualified | Higher power capability but lacks automotive reliability validation; NC pin adds routing complexity | Choose for industrial non-automotive designs needing higher dissipation without qualification constraints |
Compared with MMBZ5267BLT1G and BZX84-C36, BZT52C36LP-7 offers superior space efficiency (DFN1006-2), guaranteed AEC-Q101 compliance, and tighter thermal performance on minimal PCB area - making it optimal for next-gen automotive and portable electronics where size and qualification are non-negotiable.

FAQ
What is the maximum reverse voltage (VR) that guarantees leakage below 0.1 µA?
The datasheet specifies 0.1 µA maximum reverse current at VR = 25.2 V - this is the highest reverse voltage at which leakage is guaranteed to remain ≤0.1 µA. Exceeding 25.2 V increases leakage exponentially as the device approaches its 34.0 V minimum zener breakdown threshold.
Can BZT52C36LP-7 be used in place of a 33 V zener for tighter tolerance applications?
No - BZT52C36LP-7 has a nominal 36 V rating (34.0–38.0 V range) and is not interchangeable with 33 V devices. Its 36 V specification is fixed by process and cannot be adjusted; substituting would cause over-clamping and potential system malfunction in circuits designed for 33 V regulation.
Is the DFN1006-2 package compatible with standard reflow profiles for lead-free solder?
Yes - the device uses NiPdAu-plated copper leadframe and is qualified for JEDEC J-STD-020C Level 1 moisture sensitivity, supporting standard IPC/JEDEC lead-free reflow profiles (peak 260°C, 30 sec max) without popcorn cracking or delamination when using recommended pad layout per DS30506 page 4.
Does the +36.5 to +45.5 mV/°C temperature coefficient apply across the full operating range?
Yes - the temperature coefficient is measured and specified at IZTC = 5 mA and applies from –65°C to +150°C. However, actual drift in circuit use depends on self-heating; at 2 mA test current and 250 mW PD, junction temperature rise must be calculated using RθJA = 500 °C/W to determine net coefficient impact.
