Product details
Overview
BZT52C13LPQ-7 from Diodes Incorporated is a surface-mount Zener diode with a nominal zener voltage of 13 V, ±4.6% tolerance (12.4–14.1 V), 30 Ω maximum zener impedance at 5 mA test current, 250 mW power dissipation, and AEC-Q101 qualification for automotive voltage regulation and ESD protection circuits.
For engineers reviewing the BZT52C13LPQ-7 datasheet, BZT52C13LPQ-7 pinout, BZT52C13LPQ-7 application, or BZT52C13LPQ-7 equivalent, this device serves as a precision shunt reference in low-power supply monitoring, overvoltage clamping, and biasing networks where ultra-small footprint and automotive-grade reliability are required.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. It features a 13 V nominal regulation point with a positive temperature coefficient of +7.0 to +11.0 mV/°C and supports 1.0 mA minimum zener test current.
The device uses a planar epitaxial construction with NiPdAu-plated copper leadframe terminals and is rated for operation from –65 °C to +150 °C. Its thermal resistance (junction-to-ambient) is 500 °C/W on FR-4 PCB with minimum pad layout per Diodes' recommended footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V nominal, 12.4–14.1 V range at IZT = 5 mA - defines stable regulation window for reference or clamp |
| Zener Impedance (ZZT) | ≤30 Ω at 5 mA - ensures low dynamic resistance for tight voltage control under small-signal variation |
| Power Dissipation (PD) | 250 mW at TA = 25 °C - sets maximum continuous DC power handling on standard PCB |
| Reverse Current (IR) | ≤0.1 µA at VR = 10.4 V - guarantees high off-state blocking for leakage-sensitive bias networks |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - enables predictable forward conduction for dual-direction protection schemes |
| Temperature Coefficient | +7.0 to +11.0 mV/°C - quantifies voltage drift with ambient temperature, critical for thermal stability in automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5242B-7-F | Same 13 V nominal rating but 500 mW PD, SOD-123 package (2.7×1.6 mm), higher ZZT (35 Ω) | Larger footprint; better suited for non-automotive industrial designs with higher power margin | Select when board space allows larger package and higher power derating is needed |
| BZX384-C13,115 | 13 V rating, SOT-23 package (3.0×1.4 mm), 300 mW PD, ZZT = 25 Ω, no AEC-Q101 qualification | Not automotive-qualified; lacks PPAP capability and IATF16949 manufacturing traceability | Choose only for consumer or industrial applications where automotive compliance is not required |
Compared with MMSZ5242B-7-F and BZX384-C13,115, the BZT52C13LPQ-7 uniquely combines AEC-Q101 qualification, ultra-small DFN footprint, and automotive-grade thermal performance - making it the sole option for space-constrained, safety-critical vehicle subsystems requiring certified component change control.

FAQ
What is the maximum reverse current specification for BZT52C13LPQ-7 at 10.4 V?
The maximum reverse current (IR) is 0.1 µA at VR = 10.4 V, measured at TA = 25 °C. This low leakage ensures minimal loading on bias networks and preserves accuracy in precision reference applications across the full operating temperature range.
Is BZT52C13LPQ-7 compatible with lead-free reflow soldering processes?
Yes - the device uses NiPdAu-plated copper leadframe terminals and is fully RoHS 3 compliant. It meets MIL-STD-202 Method 208 solderability requirements and is rated for moisture sensitivity level 1, eliminating pre-bake requirements prior to standard Pb-free reflow profiles.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
The temperature coefficient is +7.0 to +11.0 mV/°C, meaning VZ increases linearly with temperature. Over –40 °C to +125 °C, this results in a total shift of approximately ±0.9–1.3 V - a known, bounded error that can be compensated in system-level calibration for high-accuracy applications.
Can BZT52C13LPQ-7 be used in place of a 12 V Zener diode in existing designs?
No - its nominal 13 V rating and 12.4–14.1 V tolerance range exceed typical 12 V system thresholds. Substituting it for a 12 V Zener may cause incorrect trip points in voltage monitors or insufficient clamping margin in protection circuits; always verify circuit margin against actual VZ min/max values.
