Product details
Overview
BZT52C5V6-13-F from Diodes Incorporated is a surface-mount 5.6 V Zener diode in SOD123 package, rated for 500 mW peak power dissipation at TL = +75°C and 370 mW at TA = +25°C, with 40 Ω maximum Zener impedance at 5 mA test current and ±2% voltage tolerance (5.2–6.0 V), used for precision voltage regulation and overvoltage protection in low-power DC rails.
For engineers reviewing the BZT52C5V6-13-F datasheet, BZT52C5V6-13-F pinout, BZT52C5V6-13-F application, or BZT52C5V6-13-F equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), reverse leakage (IR = 2.5 µA @ VR = 2 V), temperature coefficient (–2 mV/°C), and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its planar die construction ensures consistent breakdown characteristics and low dynamic impedance across the 5 mA test current.
The device exhibits a negative temperature coefficient of –2 mV/°C near 5.6 V, enabling predictable drift compensation in bias networks. It is optimized for automated SMT assembly on FR-4 PCBs with 1-inch copper pad layout per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.6 V nominal, 5.2–6.0 V range at 5 mA - defines regulated output voltage tolerance band |
| Power Dissipation (PD) | 370 mW @ TA = +25°C - sets maximum continuous power handling on standard PCB layout |
| Zener Impedance (ZZT) | 40 Ω max @ IZT = 5 mA - determines regulation stiffness under load transients |
| Reverse Leakage (IR) | 2.5 µA @ VR = 2 V - limits standby current in high-impedance bias networks |
| Temperature Coefficient | –2 mV/°C - quantifies voltage drift per degree Celsius near nominal operating point |
| Thermal Resistance (RθJA) | 338 °C/W - defines junction-to-ambient temperature rise per watt dissipated |
Pinout & Package
Package: SOD123 - surface-mount plastic case with cathode band marking, 0.010 g weight, UL 94V-0 flammability rating, and matte tin-plated Alloy 42 leadframe.
| 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 / voltage reference output | Marked by band; supplies regulated voltage when reverse biased above 5.6 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F | Same 5.6 V nominal, but SOT-323 package (smaller footprint) and 200 mW PD rating | Lower power handling limits use in >100 mA clamp circuits; better suited for space-constrained portable designs | Select when board area is critical and thermal budget permits reduced power derating |
| BZX84-C5V6 | Same 5.6 V rating, SOT-23 package, 350 mW PD, and ±5% tolerance (vs. ±2% for BZT52C5V6) | Looser voltage tolerance increases reference error in precision feedback loops | Choose only for non-critical biasing where cost outweighs accuracy requirements |

FAQ
What is the maximum reverse voltage this diode can withstand before breakdown?
The BZT52C5V6-13-F has a nominal Zener voltage of 5.6 V with a guaranteed range of 5.2–6.0 V at 5 mA test current. Breakdown occurs within this band; applying more than 6.0 V continuously exceeds specification and risks thermal runaway if power dissipation limits are exceeded.
Is this part suitable for automotive applications?
Yes - BZT52C5V6-13-F is qualified to AEC-Q101 standards, confirming its suitability for automotive applications including engine control units, body electronics, and ADAS sensor modules where reliability under temperature cycling and vibration is required.
How does the SOD123 package affect thermal performance?
The SOD123 package delivers RθJA = 338 °C/W on a standard FR-4 PCB with 1-inch copper pad, meaning junction temperature rises 338°C per watt dissipated. At 370 mW max, this yields ~125°C rise above ambient - requiring layout attention for sustained operation near upper temperature limits.
What is the significance of the "-13-F" suffix in the part number?
The "-13-F" denotes commercial-grade packaging: 10,000 units per tape-and-reel, with lead-free (F) finish and RoHS compliance. The "-7-F" variant contains 3,000 units per reel; "Q" prefix (e.g., BZT52C5V6Q-13-F) indicates automotive qualification.
