Product details
Overview
BZT52C15LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 15 V, ±8% tolerance (13.8–15.6 V), 5 mA test current, 30 Ω maximum zener impedance at IZT, and 250 mW power dissipation in DFN1006-2 package. It provides precise voltage regulation in low-power biasing and reference circuits for automotive sensor interfaces and industrial power supply feedback loops.
For engineers reviewing the BZT52C15LP-7 datasheet, BZT52C15LP-7 pinout, BZT52C15LP-7 application, or BZT52C15LP-7 equivalent, key selection criteria include zener voltage accuracy at 5 mA, thermal resistance (500 °C/W), cathode-marked DFN1006-2 footprint compatibility, 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 maintain stable voltage across its terminals when reverse-biased above VZ. Its zener voltage exhibits a +9.2 mV/°C temperature coefficient at 10.5 mA, enabling predictable drift compensation in temperature-sensitive references.
The DFN1006-2 package features NiPdAu-plated copper leads, J-STD-020C Level 1 moisture sensitivity, and UL 94V-0 mold compound - optimized for high-density PCB layouts and reflow-compatible automated assembly without lead contamination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V nominal, 13.8–15.6 V range at 5 mA - defines regulated output voltage under standard test conditions |
| Power Dissipation (PD) | 250 mW at TA = 25°C - limits continuous reverse power handling on FR-4 PCB with minimum pad layout |
| Zener Impedance (ZZT) | ≤30 Ω at IZT = 5 mA - determines voltage regulation stiffness under dynamic load changes |
| Reverse Current (IR) | ≤0.1 µA at VR = 10.5 V - ensures minimal leakage in high-impedance bias networks |
| Temp. Coefficient (αVZ) | +9.2 mV/°C at IZTC = 10.5 mA - quantifies voltage drift per degree Celsius for thermal design margining |
| Package | DFN1006-2 (1.0 × 0.6 × 0.5 mm) - ultra-small footprint compatible with 0201 land pattern and pick-and-place automation |
| Qualification | AEC-Q101 qualified - validated for automotive applications requiring high-reliability stress testing |
Pinout & Package
DFN1006-2 is a 2-terminal leadless package with exposed cathode pad and molded plastic body. Cathode is marked by a dot on top surface; terminals are co-planar NiPdAu-plated copper leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reverse breakdown reference node | Connected to lower-potential side of regulated circuit; forms reference ground return path |
| Cathode | Zener voltage reference terminal / Breakdown anode | Marked with dot; connected to higher-potential side; defines regulated output voltage relative to anode |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5245B-7-F | Same 15 V nominal VZ, but SOD-123 package (2.7 × 1.6 mm); 500 mW PD; 30 Ω ZZT | Larger footprint; higher power handling; not AEC-Q101 qualified | Preferred where board space allows and automotive qualification is unnecessary |
| BZX84-C15 | SOT-23 package; 15 V VZ; 350 mW PD; 30 Ω ZZT; no AEC-Q101 rating | Three-pin package with unused emitter; requires different land pattern and assembly setup | Selected when legacy SOT-23 tooling exists and thermal derating above 125°C is not required |
Compared with MMSZ5245B-7-F and BZX84-C15, BZT52C15LP-7 offers the smallest footprint and automotive qualification, but lower power rating - making it optimal for space-constrained, high-reliability automotive and industrial modules where 250 mW suffices.

FAQ
What is the maximum reverse voltage (VR) at which leakage current remains ≤0.1 µA?
The BZT52C15LP-7 guarantees IR ≤ 0.1 µA at VR = 10.5 V, as specified in the Electrical Characteristics table. This value is measured at TA = 25°C using short-duration pulse testing to avoid self-heating effects. Operation above this voltage increases leakage exponentially and must be avoided in low-current bias networks.
Can BZT52C15LP-7 be used in place of a 15 V Zener in a 12 V automotive system?
Yes - its 13.8–15.6 V zener range and AEC-Q101 qualification make it suitable for 12 V system references where headroom exists. However, ensure the series resistor limits IZ to 5 mA nominal and accounts for worst-case VIN up to 16 V during load dump events to stay within 250 mW PD.
Is the DFN1006-2 package compatible with standard 0201 reflow profiles?
Yes - the DFN1006-2 footprint matches JEDEC-standard 0201 land patterns. Its NiPdAu finish and J-STD-020C Level 1 moisture sensitivity allow use with standard lead-free reflow profiles (peak 260°C). Recommended pad dimensions are provided in the datasheet Figure 4 (Suggested Pad Layout).
How does the +9.2 mV/°C temperature coefficient affect long-term voltage stability?
This coefficient means VZ increases by 9.2 mV per °C rise in junction temperature. Over a –40°C to +125°C range, total drift is ~1.5 V - so designs requiring <±1% stability must include thermal compensation or operate within a narrower ambient range (e.g., 25°C ±10°C) to limit drift to ±0.1 V.
