Product details
Overview
BZT52C13LP-7 from Diodes Incorporated is a surface-mount Zener diode with nominal zener voltage 13 V (12.4–14.1 V range), 5 mA test current, 30 Ω max zener impedance at IZT, 0.1 µA max reverse leakage at 10.4 V, and ±0.4 %/°C typical temperature coefficient. It serves as precision voltage reference and overvoltage clamp in low-power analog sensor interfaces and power rail supervisors.
For engineers reviewing the BZT52C13LP-7 datasheet, BZT52C13LP-7 pinout, BZT52C13LP-7 application, or BZT52C13LP-7 equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at operating current, thermal resistance (500 °C/W), cathode-marked DFN1006-2 package compatibility, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device operates in reverse breakdown mode to regulate or clamp voltage at its specified zener voltage. It exhibits a well-defined knee at 5 mA test current, with low dynamic impedance (30 Ω) ensuring stable regulation under small-signal load variations.
The DFN1006-2 package enables high-density PCB layouts and automated placement, while NiPdAu-plated terminals ensure solderability per MIL-STD-202. Its -65 °C to +150 °C operating range and AEC-Q101 qualification support use in under-hood automotive electronics and industrial control modules.
Key Specifications

| Zener Voltage (VZ) | 13 V nominal, 12.4–14.1 V min/max at 5 mA - defines clamping threshold in protection circuits |
| Zener Impedance (ZZT) | 30 Ω max at 5 mA - determines regulation accuracy under varying load current |
| Reverse Leakage (IR) | 0.1 µA max at 10.4 V - ensures minimal standby power loss in battery-powered systems |
| Power Dissipation (PD) | 250 mW at 25 °C - sets maximum continuous dissipation before thermal derating |
| Thermal Resistance (RθJA) | 500 °C/W - requires careful PCB copper area design to maintain junction temp <150 °C |
| Temp Coefficient (αVZ) | ±0.4 %/°C typical - enables predictable drift compensation in reference designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5243B-7-F | 13 V nominal, but 300 mW PD, 100 Ω ZZT, SOT-23 package | Larger footprint, higher thermal resistance (625 °C/W), less suitable for ultra-dense layouts | Prefer when higher power margin is needed and board space allows SOT-23 |
| BZX84-C13-7 | 13 V nominal, 350 mW PD, 30 Ω ZZT, SOT-23 package, no AEC-Q101 | Higher power rating but lacks automotive qualification and green compound | Select only for non-automotive industrial use where AEC-Q101 is not required |
Compared with MMBZ5243B-7-F and BZX84-C13-7, BZT52C13LP-7 uniquely combines AEC-Q101 qualification, DFN1006-2 miniaturization, and 30 Ω low-impedance regulation-making it optimal for space- and reliability-critical automotive and portable electronics.

FAQ
What is the maximum reverse voltage (VR) that BZT52C13LP-7 can block before breakdown?
The device maintains ≤0.1 µA reverse leakage up to 10.4 V (rated as VR = 10.4 V). Breakdown begins near 12.4 V (minimum VZ), with full regulation established at 13 V nominal. Exceeding 14.1 V risks exceeding the 250 mW power limit unless current is strictly limited.
Is BZT52C13LP-7 suitable for bidirectional ESD protection?
No - it is a unidirectional Zener diode optimized for reverse-bias voltage regulation and clamping. For bidirectional ESD protection, TVS diodes such as D3V3M1U2SOT-7 or SP1003-01UTG are recommended, as they feature symmetric breakdown in both polarities.
How does the DFN1006-2 package affect thermal performance compared to SOD-123?
DFN1006-2 has higher thermal resistance (500 °C/W) than SOD-123 (~300 °C/W), due to smaller pad area and lack of leads. To compensate, use ≥10 mm² copper pour connected to both terminals and avoid thermal isolation; this maintains TJ <150 °C at 250 mW.
Does the "LP" suffix indicate low power or low profile?
The "LP" suffix denotes "Low Profile" - referencing the DFN1006-2 package height (0.5 mm max), not power rating. The device is rated for 250 mW, matching standard Zener power classes; "low profile" distinguishes it from taller packages like SOD-123 or DO-35.
