Product details
Overview
BZT52H-B62,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD123F package, rated for 62 V nominal breakdown voltage at 2 mA test current, 150 Ω maximum differential resistance, and 830 mW total power dissipation at Tamb ≤ 25 °C. It serves as a precision reference or overvoltage clamp in low-power analog supply rails and sensor interface circuits.
For engineers reviewing the BZT52H-B62,115 datasheet, BZT52H-B62,115 pinout, BZT52H-B62,115 application, or BZT52H-B62,115 equivalent, this page delivers verified Zener parameters, thermal performance under PCB-mount conditions, cathode/anode terminal mapping, and direct-fit alternatives for voltage reference design validation.
Technical Context
This Zener diode operates in reverse-biased avalanche mode with a specified 62 V working voltage (VZ) at IZ = 2 mA, exhibiting a temperature coefficient of +4.3 mV/K and reverse current < 0.1 μA at VR = 49.6 V. Its junction-to-ambient thermal resistance is 330 K/W on standard FR4 PCB.
The device uses planar epitaxial technology to achieve tight ±2 % VZ tolerance, low dynamic impedance (rdif ≤ 150 Ω), and stable regulation across -65 °C to +150 °C ambient range. It is not automotive-qualified per Rev. 7 (January 2023) documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VZ | 62 V nominal at IZ = 2 mA; ensures stable reference within ±2 % (58.0–66.0 V) for precision biasing |
| Differential Resistance rdif | ≤150 Ω at IZ = 2 mA; minimizes output voltage shift under load variation in feedback networks |
| Total Power Dissipation Ptot | 830 mW at Tamb ≤ 25 °C on FR4 PCB; defines maximum continuous DC power handling before thermal derating |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA; enables use as polarity protection or clamping diode in forward bias |
| Reverse Current IR | <0.1 μA at VR = 49.6 V; guarantees low leakage in high-impedance reference nodes |
| Temperature Coefficient SZ | +4.3 mV/K at IZ = 2 mA; quantifies VZ drift per degree Celsius for thermal stability analysis |
| Junction Temperature Tj | 150 °C maximum; sets upper limit for safe operation under sustained power dissipation |
Pinout & Package
SOD123F surface-mount plastic package: 2.5–2.7 mm length, 1.0–1.2 mm width, 0.55–0.70 mm height, cathode marked by bar on top surface.
| 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 must be observed for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % VZ tolerance | Enables tighter regulation than ±5 % variants, reducing need for post-calibration in reference designs |
| 830 mW power rating | Supports higher current regulation (up to ~13.5 mA at 62 V) without external heatsinking on standard PCB |
| SOD123F footprint | Compatible with automated reflow assembly; occupies only 2.7 × 1.2 mm area for space-constrained layouts |
| 150 °C max junction temp | Permits operation in industrial environments where ambient exceeds 85 °C with appropriate derating |
| Low 0.1 μA IR @ 49.6 V | Maintains accuracy in high-Z voltage dividers and battery-monitoring circuits with minimal error contribution |
Applications
| Power Supply Reference | Sensor Biasing |
|---|---|
|
Use Scenario: Providing stable 62 V reference for isolated DC-DC converter feedback loop in telecom power modules. IC Role / Device Role / Timing Role: Zener diode acts as secondary-side voltage sense element, replacing optocoupler-based regulation in cost-sensitive designs. Use Value: Delivers ±2 % initial accuracy and +4.3 mV/K thermal drift-sufficient for Class II efficiency compliance without trimming. |
Use Scenario: Biasing photodiode anode in UV radiation detector with 60–65 V reverse bias requirement. IC Role / Device Role / Timing Role: Functions as fixed-voltage current source via series resistor, setting precise photocurrent operating point. Use Value: Low 0.1 μA leakage prevents signal corruption in picoamp-level photocurrent measurement paths. |

|
Use Scenario: Protecting 60 V-rated CAN transceiver input against load-dump transients in 48 V vehicle subsystems. IC Role / Device Role / Timing Role: Shunts surge energy above 62 V to ground, limiting peak voltage seen by downstream IC pins. Use Value: 40 W non-repetitive peak power rating (100 μs pulse) absorbs ISO 7637-2 Pulse 5a without failure. |
Use Scenario: Generating clean reset signal for ARM Cortex-M0+ MCU when 5 V rail rises above 4.75 V during power-up. IC Role / Device Role / Timing Role: Used in comparator reference leg with resistor divider to detect VCC threshold crossing. Use Value: Tight ±2 % VZ eliminates need for external trim pot, reducing BOM count and layout area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52H-C62,115 | ±5 % VZ tolerance (58–66 V), 200 Ω rdif, same SOD123F package | Acceptable where cost sensitivity outweighs regulation accuracy; higher rdif increases load regulation error | Select for non-critical biasing where ±5 % VZ meets system margin requirements |
| MMBZ5262B-7-F | ±5 % VZ, 100 Ω rdif, SOT-23 package, 500 mW Ptot | Smaller footprint but lower power rating; unsuitable for >8 mA continuous Zener current | Choose when board space is constrained and thermal budget allows derated operation |
Compared with BZT52H-B62,115, the C62 variant trades accuracy for cost in non-precision roles, while MMBZ5262B sacrifices 330 mW power headroom for 40 % smaller area-making BZT52H-B62,115 optimal for thermally demanding, accuracy-critical 62 V references.

FAQ
What is the maximum reverse current specification for BZT52H-B62,115 at its rated breakdown voltage?
At VR = 49.6 V (80 % of 62 V), the reverse current IR is guaranteed ≤ 0.1 μA. This ultra-low leakage supports high-impedance reference applications such as precision voltage dividers and battery monitoring circuits where even nanoamp-level errors degrade accuracy.
Can BZT52H-B62,115 be used in automotive applications?
No. Per Nexperia Rev. 7 (January 2023), the BZT52H series is explicitly designated as non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, select Nexperia's -Q qualified equivalents like PZT52H-B62,115 or consult official automotive-part cross-reference tables.
How does thermal resistance affect BZT52H-B62,115's power handling on a PCB?
With Rth(j-a) = 330 K/W on standard FR4, dissipating 830 mW raises junction temperature by 274 °C above ambient-exceeding the 150 °C limit. Therefore, full-rated power is only achievable with thermal relief (e.g., 1 cm² cathode pad, Rth(j-sp) = 70 K/W), requiring strict derating above 25 °C ambient.
Is the SOD123F package compatible with standard reflow soldering profiles?
Yes. Nexperia specifies reflow soldering as the only recommended method for SOD123F. The footprint in Figure 12 defines exact solder land dimensions (2.8 × 1.2 mm per pad), paste deposit volume, and solder resist openings-ensuring reliable joint formation without tombstoning or voiding when using IPC-J-STD-020-compliant thermal profiles.
