Product details
Overview
BZT52C13T-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), 300 mW power dissipation, 30 Ω maximum zener impedance at 5 mA, and SOD523 package. It provides precise voltage regulation in low-power biasing, reference, and overvoltage protection circuits for consumer power supplies and sensor signal conditioning.
For engineers reviewing the BZT52C13T-7 datasheet, BZT52C13T-7 pinout, BZT52C13T-7 application, or BZT52C13T-7 equivalent, key selection criteria include zener voltage accuracy at 5 mA test current, thermal resistance (417 °C/W junction-to-ambient), reverse leakage (<0.1 µA at 11 V), temperature coefficient (+7.0 mV/°C), and SOD523 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 13 V nominal rating targets mid-range voltage reference needs where tighter tolerance than general-purpose Zeners is required but ultra-low drift is not critical.
The device uses alloy-42 leadframe with matte tin annealed finish, rated for -55 °C to +150 °C operation, and exhibits a positive temperature coefficient of +7.0 mV/°C - enabling predictable drift compensation in multi-diode reference strings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.0 V nominal, 12.4–14.1 V range at 5 mA - ensures stable reference within ±4.6% under standard test conditions |
| Power Dissipation (PD) | 300 mW - supports continuous regulation in compact SOD523 layout without forced cooling |
| Zener Impedance (ZZT) | 30 Ω max at 5 mA - limits output voltage variation under small-signal current changes |
| Reverse Leakage (IR) | <0.1 µA at 11 V - minimizes parasitic current draw in high-impedance bias networks |
| Temperature Coefficient | +7.0 mV/°C - enables predictable voltage drift for temperature-compensated references |
| Thermal Resistance (RθJA) | 417 °C/W - defines derating slope: full power only at ≤25 °C ambient; zero power at ~150 °C |
Pinout & Package
Package: SOD523 - ultra-compact 1.25 mm × 0.85 mm surface-mount outline with cathode band marking; 0.001 g mass; JEDEC-compliant, RoHS- and halogen-free green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to lower-potential node; reverse-biased operation requires cathode at higher potential |
| Cathode | Zener breakdown terminal / regulated output node | Marked by band; delivers stable 13 V when reverse current ≥1 mA flows into this terminal |
Key Features
| Feature | Design Value |
|---|---|
| Low-profile SOD523 package | Enables placement in space-constrained designs such as wearables and IoT sensor nodes |
| Totally lead-free & RoHS 3 compliant | Meets global environmental regulations without compromising solderability or reliability |
| Moisture Sensitivity Level 1 | Eliminates bake requirements before reflow, reducing manufacturing overhead |
| Flat lead design | Improves thermal conduction from junction to PCB copper, supporting higher power density |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5242B-7-F | 13 V nominal, ±5% tolerance, 500 mW PD, SOD-123 package (larger footprint) | Higher power handling but requires 2.5× more board area; less suitable for ultra-dense layouts | Select when thermal margin >300 mW is needed and SOD-123 is already standardized in design |
| BZX584C13 | 13 V nominal, ±5% tolerance, 300 mW PD, SOT-23 package (3-pin, cathode-anode-marked) | Requires orientation-aware placement; larger than SOD523 but offers better thermal relief via extra pad | Prefer when existing SOT-23 tooling or legacy footprint reuse drives package choice |
Compared with MMSZ5242B-7-F and BZX584C13, BZT52C13T-7 delivers identical voltage regulation performance in the smallest available footprint, making it optimal for miniaturized designs where board space is constrained and thermal load remains within 300 mW limits.

FAQ
What is the maximum reverse current specification for BZT52C13T-7 at 11 V?
The maximum reverse leakage current is 0.1 µA at 11 V and 25 °C, per the Electrical Characteristics table. This value remains ≤0.5 µA up to 125 °C, ensuring minimal loading in high-impedance reference networks across the full operating temperature range.
Can BZT52C13T-7 be used in automotive applications?
Yes - the base BZT52C13T-7 meets JEDEC reliability standards referenced in AEC-Q101. For full automotive qualification (AEC-Q101 stress testing, PPAP, IATF 16949 manufacturing), the Q-suffix variant BZT52C13TQ-7-F must be specified per Diodes' automotive product listing.
What is the thermal derating behavior above 25 °C ambient?
Derating begins linearly at 25 °C: power dissipation reduces by 0.72 mW/°C above ambient, reaching zero at approximately 150 °C. This corresponds to the stated RθJA of 417 °C/W on FR-4 with 2 oz. copper and 1.92 mm² pad area.
How is polarity identified on the SOD523 package?
Polarity is marked by a visible cathode band on the top surface of the SOD523 package. The band aligns with the cathode terminal; the unmarked end is the anode. This matches the standard SOD523 mechanical drawing and is verified in Diodes' package outline documentation.
