Product details
Overview
BZT52H-C13-QX from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 13 V nominal breakdown voltage at IZ = 5 mA, with 830 mW total power dissipation and AEC-Q101 qualification for automotive voltage regulation and reference applications.
For engineers reviewing the BZT52H-C13-QX datasheet, BZT52H-C13-QX pinout, BZT52H-C13-QX application, or BZT52H-C13-QX equivalent, this part delivers stable 13 V regulation under 5 mA test current, supports surface-mounted design in space-constrained automotive ECUs, and provides verified thermal resistance (Rth(j-sp) = 70 K/W) for reliable operation up to 150 °C junction temperature.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable 13 V reference across its terminals when reverse current exceeds the knee threshold. Its differential resistance of 110 Ω at IZ = 5 mA ensures low dynamic impedance for effective noise suppression in feedback paths.
The device features a negative temperature coefficient of +0.1 mV/K at IZ = 5 mA, enabling predictable drift compensation in precision analog circuits. It is qualified per AEC-Q101 with Tj rating up to 150 °C and storage temperature range of −65 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 12.4 V to 14.1 V at IZ = 5 mA - defines usable regulation window for 13 V nominal reference |
| Differential Resistance rdif | 110 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - limits conduction loss during forward-biased transient conditions |
| Junction Temperature Tj | −65 °C to +150 °C - enables deployment in under-hood automotive environments |
| Reverse Current IR | 10 μA max at VR = 10.4 V - quantifies leakage before breakdown onset |
| Thermal Resistance Rth(j-sp) | 70 K/W - measures junction-to-solder-point heat transfer efficiency for thermal design |
Pinout & Package
SOD123F surface-mount plastic package: 2-terminal, flat lead, cathode-marked with bar; dimensions 3.4–3.6 mm × 2.5–2.7 mm × 1.0–1.2 mm; optimized for reflow soldering on FR4 PCBs with single-sided copper and tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct orientation during placement |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-bias polarity must be maintained for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
| ±5 % voltage tolerance | Enables cost-optimized selection for non-critical regulation where tighter tolerances are unnecessary |
| 830 mW power rating | Supports higher-current shunt regulation than standard 500 mW Zeners without derating at 25 °C |
| SOD123F footprint | Reduces board area by ~30 % vs. SOD123 while maintaining compatibility with existing pick-and-place tooling |
| 150 °C junction rating | Permits operation in high-ambient environments such as engine control modules and ADAS sensor housings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52H-B13-Q | ±2 % tolerance (12.7–13.3 V), lower rdif (90 Ω max) | Better regulation stability in precision feedback loops | Select when tighter voltage control outweighs cost sensitivity |
| MMBZ5243B-7-F | ±5 % tolerance (12.35–13.65 V), SOT-23 package, 350 mW Ptot | Smaller footprint but lower power handling and no AEC-Q101 rating | Choose only for non-automotive, low-power consumer designs with space constraints |
Compared with BZT52H-C13-QX, the BZT52H-B13-Q offers improved regulation accuracy at higher cost, while MMBZ5243B-7-F sacrifices automotive qualification and thermal robustness for miniaturization-making the C-grade part optimal for cost-sensitive, thermally demanding automotive applications.

FAQ
What is the maximum reverse current IZSM for BZT52H-C13-QX?
The non-repetitive peak reverse current is 2.5 A at tp = 100 μs and Tamb = 25 °C, as specified in Table 8. This surge rating enables transient overvoltage clamping in automotive load-dump scenarios without permanent degradation.
Does BZT52H-C13-QX require heatsinking for 830 mW operation?
No external heatsink is required at 25 °C ambient if mounted per specification: FR4 PCB with single-sided copper, tin-plated, and 1 cm² cathode pad. The Rth(j-sp) of 70 K/W ensures junction temperature remains below 150 °C under these conditions.
How does the ±5 % tolerance affect regulation accuracy in a 13 V reference circuit?
At IZ = 5 mA, the actual breakdown voltage ranges from 12.4 V to 14.1 V. For applications requiring tighter regulation, use the BZT52H-B13-Q (±2 %) or add post-regulation filtering; the C-grade is intended for cost-sensitive, non-precision roles like bulk voltage clamping.
Can BZT52H-C13-QX replace older BZT52C13S in new designs?
Yes-BZT52H-C13-QX supersedes BZT52C13S with identical electrical specs, enhanced AEC-Q101 qualification, and improved thermal performance (Rth(j-sp) reduced from 100 K/W to 70 K/W), making it a drop-in upgrade for automotive and industrial revisions.
