Product details
Overview
BZT52H-A13X from Nexperia is a precision Zener voltage regulator diode in SOD123F package, designed for low-power voltage reference and overvoltage protection in biasing, feedback, and clamp circuits. It delivers a nominal 13 V breakdown voltage at 5 mA with ±1 % tolerance, 110 Ω differential resistance, and operates up to 150 °C junction temperature - deployed in industrial power supply feedback loops and sensor signal conditioning stages.
For engineers reviewing the BZT52H-A13X datasheet, BZT52H-A13X pinout, BZT52H-A13X application, or BZT52H-A13X equivalent, this page provides verified Zener parameters (VZ, rdif, IR, TC), thermal resistance data (Rth(j-a), Rth(j-sp)), and real-world design context for stable 13 V reference generation under 250 mA forward current and 830 mW total dissipation limits.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with tightly controlled VZ = 12.87–13.13 V at IZ = 5 mA and exhibits a positive temperature coefficient of +0.1 mV/K, enabling predictable drift compensation in temperature-sensitive references. Its low 110 Ω differential resistance ensures minimal output impedance variation across load changes.
The device uses planar epitaxial construction for stable long-term performance and integrates into compact SMD layouts via its SOD123F footprint - optimized for reflow soldering on FR4 PCBs with single-sided copper and tin plating, supporting thermal resistance of 150 K/W (junction-to-solder point) and 330 K/W (junction-to-ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.87–13.13 V at IZ = 5 mA - defines precise regulation threshold for 13 V reference designs |
| Differential Resistance (rdif) | 110 Ω max - ensures stable output voltage under varying load currents |
| Reverse Current (IR) | ≤10 μA at VR = 10.4 V - guarantees low leakage in standby or high-impedance feedback paths |
| Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 board |
| Junction Temperature (Tj) | −65 to +150 °C - enables operation in extended industrial environments without derating below −40 °C |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports efficient forward conduction in dual-purpose clamp/rectifier roles |
| Thermal Resistance (Rth(j-sp)) | 150 K/W - quantifies heat transfer efficiency from junction to cathode solder point for thermal layout planning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C13 | ±5 % tolerance (12.4–13.6 V), higher rdif (150 Ω), same SOD123F package | Acceptable where 13 V accuracy <±3 % suffices; lower cost for non-critical biasing | Select for cost-sensitive industrial controls where calibration compensates for wider VZ spread |
| MMSZ5243B | ±5 % tolerance, 500 mW Ptot, SOD-123 package (slightly larger pad layout) | Limited to lower-power applications; unsuitable for sustained 830 mW dissipation | Choose only for legacy designs requiring direct MMSZ5243B footprint compatibility and <500 mW loading |
Compared with BZT52H-A13X, BZT52C13 trades precision for cost in non-critical references, while MMSZ5243B sacrifices power handling and thermal performance for legacy footprint alignment - making the A13X optimal for new 13 V designs demanding ±1 % stability and full 830 mW capability.

FAQ
What is the guaranteed Zener voltage range for BZT52H-A13X at 5 mA test current?
The guaranteed Zener voltage range is 12.87 V to 13.13 V at IZ = 5 mA and Tj = 25 °C, reflecting its ±1 % tolerance grade. This range remains valid across the full operating junction temperature range (−65 °C to +150 °C), with temperature coefficient of +0.1 mV/K measured at IZ = 2 mA.
Can BZT52H-A13X be used in parallel for higher power dissipation?
No - Zener diodes must not be paralleled due to mismatched VZ and thermal runaway risk. The BZT52H-A13X is rated for 830 mW at Tamb ≤ 25 °C on a standard FR4 PCB; for higher power, use a single higher-rated device or redesign thermal layout with enlarged copper pour on cathode pad.
How does the SOD123F package affect thermal performance compared to SOD-123?
The SOD123F has identical outline but features flattened leads for improved coplanarity and solder joint reliability. Its Rth(j-sp) is 150 K/W (vs. ~170 K/W for standard SOD-123), enabling better heat transfer to the PCB cathode pad - critical for maintaining Tj < 150 °C under 830 mW load.
Is BZT52H-A13X qualified for automotive applications?
No - per Nexperia's revision history (Rev. 7, Jan 2023), the BZT52H series is explicitly designated non-automotive qualified. For automotive use, select the BZT52H-Q series variants, which undergo AEC-Q200 stress testing and include enhanced process controls for automotive-grade reliability.
