Product details
Overview
BZT52H-C5V6-QX from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 5.6 V nominal breakdown voltage at 5 mA, 400 Ω maximum differential resistance, and 830 mW total power dissipation. It is AEC-Q101 qualified and used for precision voltage regulation in automotive body control modules.
For engineers reviewing the BZT52H-C5V6-QX datasheet, BZT52H-C5V6-QX pinout, BZT52H-C5V6-QX application, or BZT52H-C5V6-QX equivalent, this page delivers verified Zener parameters, thermal resistance values, reverse current limits at 1 V, temperature coefficient behavior, and automotive-grade reliability context - all confirmed from Nexperia's official product data sheet Rev. 1 (October 2021).
Technical Context
This Zener diode operates in reverse-bias breakdown mode with a specified 5.6 V nominal Zener voltage at IZ = 5 mA, exhibiting a temperature coefficient of −2.0 to +2.5 mV/K and 1 μA maximum reverse leakage at 4.0 V. Its low 400 Ω differential resistance ensures stable regulation under varying load currents.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it achieves 70 K/W junction-to-solder-point thermal resistance when mounted with a 1 cm² cathode pad, enabling reliable operation up to 150 °C junction temperature in automotive ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.20 V to 6.00 V at IZ = 5 mA - defines regulation band for stable reference in feedback loops |
| Differential Resistance (rdif) | ≤ 400 Ω - low impedance maintains voltage stability against current variations |
| Reverse Current (IR) | ≤ 1 μA at VR = 4.0 V - ensures minimal quiescent power loss in standby mode |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard PCB layout |
| Thermal Resistance (Rth(j-sp)) | 70 K/W - quantifies junction-to-solder-point heat transfer efficiency for thermal design margining |
| Temperature Coefficient (SZ) | −2.0 to +2.5 mV/K - indicates voltage drift per degree Celsius across operating temperature range |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - defines conduction threshold in forward bias for protection or clamping roles |
Pinout & Package
SOD123F plastic surface-mounted package with 2 leads: compact 3.6 mm × 1.7 mm footprint, 0.7 mm height, and flat lead profile optimized for automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-bias polarity enables Zener breakdown operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and lighting systems |
| ±5 % voltage tolerance | Enables cost-optimized regulation where tight accuracy is not required, e.g., non-critical biasing |
| 830 mW power rating | Supports higher-current regulation than standard 500 mW Zeners without derating on standard FR4 |
| SOD123F package | Reduces board space by 30 % vs. DO-214AC while maintaining solder joint reliability under thermal cycling |
| 150 °C max junction temperature | Permits operation in under-hood environments without external heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52H-B5V6-Q | ±2 % tolerance, 60 Ω rdif, 2 μA IR at 4.0 V | Higher accuracy and lower dynamic impedance, but reduced surge immunity (IZSM = 6 A vs. 6.0 A) | Select when tighter regulation (<±0.1 V) and faster transient response are required in non-automotive designs |
| MMSZ5232B-TP | ±5 % tolerance, 150 Ω rdif, 5 μA IR at 4.0 V, SOD-123 package | Lower power rating (500 mW), no AEC-Q101 qualification, wider VZ distribution | Choose for cost-sensitive consumer applications where automotive qualification is unnecessary |
Compared with BZT52H-C5V6-QX, the BZT52H-B5V6-Q offers superior regulation precision at the expense of slightly reduced surge robustness, while MMSZ5232B-TP trades automotive reliability and thermal performance for lower unit cost in commercial-grade systems.

FAQ
What is the maximum reverse voltage before breakdown for BZT52H-C5V6-QX?
The device exhibits <1 μA reverse current up to 4.0 V; breakdown begins near 5.2 V and reaches nominal 5.6 V at 5 mA test current. The absolute maximum non-repetitive peak reverse voltage is limited by PZSM = 40 W for 100 μs pulses, corresponding to ~120 V at IZSM = 6.0 A.
How does thermal resistance affect derating in a real PCB layout?
With Rth(j-sp) = 70 K/W and a 1 cm² cathode pad, junction temperature rises 56 °C above ambient at 800 mW dissipation. Derating to 500 mW is recommended above 70 °C ambient to maintain Tj ≤ 150 °C, per Nexperia's limiting values table.
Is the SOD123F package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering only, with peak temperature ≤ 260 °C for ≤ 10 seconds. The SOD123F outline in Figure 11 and footprint in Figure 12 define exact land patterns; no wave soldering or hand-soldering is qualified per datasheet Section 13.
What is the significance of the 'C' in BZT52H-C5V6-QX?
The 'C' denotes the ±5 % tolerance grade within the BZT52H-Q series. Per Table 4 and Table 8, 'C' devices have the widest VZ range (5.20–6.00 V), higher rdif (400 Ω), and lower cost compared to 'A' (±1 %) and 'B' (±2 %) variants, targeting general-purpose regulation.
