Product details
Overview
BZT52C5V6-13 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 typical 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 analog and digital supply rails.
For engineers reviewing the BZT52C5V6-13 datasheet, BZT52C5V6-13 pinout, BZT52C5V6-13 application, or BZT52C5V6-13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 338 °C/W), reverse leakage (IR = 2.5 µA @ VR = 5 V), temperature coefficient (–2 mV/°C), and AEC-Q101 qualification 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 range.
The device exhibits a negative temperature coefficient of –2 mV/°C near 5.6 V, enabling predictable drift compensation in voltage-reference circuits. It is optimized for automated SMT assembly with matte tin-plated terminals and meets J-STD-020 Level 1 moisture sensitivity requirements.
Key Specifications

| Power Dissipation (PD) | 370 mW @ TA = +25°C - sets maximum continuous power in still-air PCB mounting |
| Zener Impedance (ZZT) | 40 Ω @ IZT = 5 mA - determines AC regulation error under small-signal ripple |
| Reverse Leakage (IR) | 2.5 µA @ VR = 5 V - limits quiescent current in standby voltage-monitoring circuits |
| Temperature Coefficient | –2 mV/°C @ IZTC = 2 mA - quantifies voltage drift per degree Celsius near operating point |

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); RθJA = 300 °C/W; ZZT = 30 Ω @ 20 mA | Higher power density but requires tighter layout control; better suited for space-constrained portable designs | Select when board area is critical and thermal management allows higher junction temperature rise |
| 1N4734A | Through-hole DO-41 package; 1 W rating; 5.6 V ±5%; ZZT = 5 Ω @ 45 mA; no AEC-Q101 qualification | Lacks automotive qualification and SMT compatibility; intended for prototyping or legacy through-hole systems | Choose only for non-automotive, non-SMT applications where higher power and manual assembly are acceptable |
Compared with MMBZ5232BS-7-F and 1N4734A, BZT52C5V6-13 offers optimal balance of AEC-Q101 compliance, SOD123 manufacturability, and 5.6 V regulation accuracy-making it preferred for volume automotive and industrial SMT production where reliability and process compatibility are mandatory.

FAQ
What is the maximum reverse voltage (VR) this diode can withstand before breakdown?
The BZT52C5V6-13 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 begins at the minimum specified voltage (5.2 V), and operation above 6.0 V risks exceeding its safe operating area under sustained bias. The absolute maximum non-repetitive peak reverse voltage is not separately defined beyond the Zener range.
Is this part suitable for use in automotive applications?
Yes - BZT52C5V6-13 is explicitly qualified to AEC-Q101 standards, confirming reliability for automotive environments including under-hood and cabin modules. Its SOD123 package, lead-free plating, and thermal performance meet stringent automotive qualification requirements.
How does the temperature coefficient affect regulation accuracy over –40°C to +125°C?
With a temperature coefficient of –2 mV/°C, the Zener voltage decreases linearly with rising temperature. Over a 165°C span, total drift is approximately –330 mV - meaning regulation shifts from ~5.75 V at –40°C to ~5.42 V at +125°C. This must be accounted for in precision reference designs.
Can this diode replace a 5.1 V Zener in an existing circuit?
No - BZT52C5V6-13 is not a drop-in replacement for 5.1 V Zeners like BZT52C5V1 due to its higher nominal voltage (5.6 V vs. 5.1 V) and different temperature coefficient (–2 mV/°C vs. –2.7 mV/°C). Substituting it would raise regulated voltage by ~0.5 V and alter thermal drift behavior.
