Product details
Overview
BZX84C13T-7-F from Diodes Incorporated is a 13 V, 150 mW surface-mount Zener diode in SOT-523 package, with nominal zener voltage 13 V (min 12.4 V, max 14.1 V at 5 mA), zener impedance 30 Ω at test current, and reverse leakage ≤0.1 µA at 8 V. It provides precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the BZX84C13T-7-F datasheet, BZX84C13T-7-F pinout, BZX84C13T-7-F application, or BZX84C13T-7-F equivalent, key selection criteria include zener voltage tolerance, dynamic impedance at 5 mA, power derating above 25°C, thermal resistance (833 °C/W), and RoHS-compliant matte tin plating on Alloy 42 leadframe.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load or supply conditions. Its planar die construction ensures consistent breakdown characteristics and low leakage, while the SOT-523 package enables high-density PCB layouts in space-constrained applications.
It is rated for 150 mW power dissipation at 25°C ambient, with linear derating to zero at 150°C junction temperature. The device exhibits a positive temperature coefficient of +7.0 to +11.0 mV/°C at 5 mA, supporting predictable drift behavior in temperature-sensitive references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13 V nominal, 12.4–14.1 V range at 5 mA - defines regulated output voltage tolerance in reference designs |
| Power Dissipation (PD) | 150 mW at TA = 25°C - limits continuous current to ~11.5 mA at 13 V without heatsinking |
| Zener Impedance (ZZT) | 30 Ω at IZT = 5 mA - determines output voltage variation under load changes |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 8 V - ensures minimal error current in high-impedance bias networks |
| Thermal Resistance (RθJA) | 833 °C/W - requires careful layout (FR-4 pad per AP02001) to avoid exceeding 150°C junction limit |
| Tempco (αVZ) | +7.0 to +11.0 mV/°C at 5 mA - enables compensation design for temperature-induced voltage drift |
Pinout & Package
Package: SOT-523 - ultra-small plastic surface-mount case (1.6 mm × 0.8 mm × 0.5 mm), UL 94V-0 rated, moisture sensitivity level 1.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5243B-7-F | Zener voltage 13 V (12.35–13.65 V), PD = 350 mW, SOT-23 package | Larger footprint; higher power handling but 3× board area | Select when >150 mW dissipation or legacy SOT-23 layout compatibility required |
| BZX84C13LT1G | Zener voltage 13 V (12.4–14.1 V), PD = 200 mW, SOT-23 package | SOT-23 instead of SOT-523; 33% higher power rating | Choose for improved thermal margin in moderate-power analog rails where space allows |
Compared with BZX84C13T-7-F, MMBZ5243B-7-F offers higher power but larger size, while BZX84C13LT1G trades ultra-miniaturization for enhanced thermal robustness - both require layout revision but retain identical electrical regulation behavior.

FAQ
What is the maximum reverse voltage this Zener can safely clamp without degradation?
The BZX84C13T-7-F is rated for continuous operation up to its nominal zener voltage (13 V) with specified leakage and impedance. It withstands short-duration transients beyond 14.1 V per datasheet VZ max, but sustained reverse bias above 14.1 V risks thermal runaway due to its 150 mW power limit and 833 °C/W thermal resistance.
Can this device be used in a 5 V system for voltage reference generation?
No - the BZX84C13T-7-F is a 13 V zener and cannot regulate at 5 V. For 5 V reference, use BZX84C5V1T-7-F (5.1 V) or BZX84C5V6T-7-F (5.6 V), which share identical SOT-523 packaging, RoHS compliance, and thermal specs but target lower voltage rails.
Is the SOT-523 package compatible with standard reflow profiles for lead-free assembly?
Yes - the device is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity, with matte tin plating that meets MIL-STD-202 Method 208 solderability requirements. Peak reflow temperature must not exceed 260°C for ≤10 seconds to avoid delamination or marking degradation.
How does temperature affect its zener voltage stability in real-world operation?
Its temperature coefficient ranges from +7.0 to +11.0 mV/°C at 5 mA, meaning voltage increases ~9 mV per °C rise. At 70°C ambient (45°C rise), VZ shifts +0.4 V - within the 12.4–14.1 V spec band. Derating power to 100 mW at 70°C maintains safe junction temperature and predictable drift.
