Product details
Overview
BZT52H-C9V1,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 9.1 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 100 Ω maximum differential resistance - used for precision voltage reference and overvoltage protection in low-power analog supply rails.
For engineers reviewing the BZT52H-C9V1,115 datasheet, BZT52H-C9V1,115 pinout, BZT52H-C9V1,115 application, or BZT52H-C9V1,115 equivalent, this page delivers verified Zener parameters, thermal performance data, cathode/anode terminal mapping, and direct-fit alternatives for stable 9.1 V regulation in space-constrained PCB designs.
Technical Context
This Zener operates in reverse-bias breakdown mode with a temperature coefficient of +0.5 mV/K at IZ = 5 mA, enabling predictable drift compensation in temperature-sensitive references. Its 150 °C maximum junction temperature and 70 K/W junction-to-solder-point thermal resistance support reliable operation under sustained 830 mW dissipation on standard FR4 PCBs.
The device exhibits ≤10 μA reverse current at 7.3 V (VR), <0.9 V forward voltage at 10 mA, and 150 A non-repetitive peak reverse surge capability (tp = 100 μs), making it suitable for transient suppression and clamping in low-energy signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 9.1 V nominal at IZ = 5 mA; ±5 % tolerance ensures stable regulation within 8.5–9.6 V range under production conditions. |
| Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C; enables continuous 9.1 V clamping at ~91 mA without heatsinking on standard FR4 board. |
| Differential Resistance (rdif) | 100 Ω max at IZ = 5 mA; limits output impedance for stable reference voltage under load variation. |
| Reverse Current (IR) | ≤10 μA at VR = 7.3 V; ensures minimal leakage in high-impedance bias networks and sensing circuits. |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA; supports bidirectional clamping and low-loss forward conduction during fault events. |
| Thermal Resistance (Rth(j-sp)) | 70 K/W junction-to-solder-point; allows accurate thermal modeling when mounted on 1 cm² cathode pad per datasheet layout. |
| Surge Capability (IZSM) | 3.0 A non-repetitive peak reverse current (tp = 100 μs); provides robust ESD/overvoltage immunity in I/O protection circuits. |
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; carries reverse current during Zener operation. |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes bias path for reverse-bias conduction and thermal dissipation path. |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance | Enables cost-effective selection for non-critical 9.1 V references where tighter tolerance is unnecessary. |
| 830 mW power rating | Supports higher-current regulation than standard 500 mW Zeners, reducing need for parallel devices in 50–100 mA applications. |
| 100 Ω differential resistance | Minimizes output voltage shift across 1–10 mA load changes, improving stability in feedback divider networks. |
| SOD123F footprint | Compatible with standard reflow soldering; occupies only 2.9 × 1.6 mm PCB area, ideal for dense mixed-signal layouts. |
| +0.5 mV/K tempco | Provides predictable positive drift, simplifying temperature-compensated reference design versus negative-coefficient variants. |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C9V1,115 | Same 9.1 V, ±5 %, SOD123F package but older revision (Rev. 6); lacks updated non-automotive qualification status. | No functional difference in regulation performance; identical thermal and electrical specs per datasheet Rev. 7. | Select if legacy BOM compliance required; otherwise prefer BZT52H-C9V1,115 for latest reliability screening. |
| MMSZ5240B-TP | 9.1 V, ±5 %, SOD-123 package; 500 mW Ptot, 150 Ω rdif, 100 °C Tj max - lower power and thermal capability. | Not suitable for >60 mA continuous Zener current or high-temp industrial environments (>105 °C). | Use only in low-power consumer applications where 500 mW rating suffices and thermal margin is not critical. |

FAQ
What is the maximum continuous Zener current for BZT52H-C9V1,115 at 70 °C ambient?
At Tamb = 70 °C, derated power is 581 mW (using 830 mW × [1 − (70−25)/150]), yielding ~64 mA maximum continuous Zener current (581 mW ÷ 9.1 V). This assumes standard FR4 mounting with 1 cm² cathode pad per datasheet thermal model.
Does BZT52H-C9V1,115 support reflow soldering, and what profile is recommended?
Yes - only reflow soldering is recommended per datasheet Section 12. Use JEDEC J-STD-020-compliant lead-free profile: peak temperature 260 °C, time above 217 °C ≤ 60 s, ramp rate ≤ 3 °C/s. Avoid wave or hand soldering due to thermal stress risk.
How does the +0.5 mV/K temperature coefficient affect long-term reference stability?
Over a 100 °C junction temperature swing (25–125 °C), the coefficient causes +50 mV drift (0.5 mV/K × 100 K), or +0.55 % of 9.1 V. For high-stability applications, pair with NTC thermistors or use in temperature-controlled zones.
Can BZT52H-C9V1,115 replace BZX84-C9V1 in existing designs?
No - BZX84-C9V1 uses SOT-23 package (3-pin, different footprint and thermal path), while BZT52H-C9V1,115 is SOD123F (2-pin, smaller, lower thermal resistance). PCB redesign and layout verification are required for substitution.
