Product details
Overview
BZT52H-C7V5 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 7.5 V nominal breakdown voltage at 5 mA, 80 Ω maximum differential resistance, and 830 mW total power dissipation at Tamb ≤ 25 °C. It provides stable voltage regulation in low-power supply rails and reference circuits.
For engineers reviewing the BZT52H-C7V5 datasheet, BZT52H-C7V5 pinout, BZT52H-C7V5 application, or BZT52H-C7V5 equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (150 K/W junction-to-solder-point), reverse current (≤1 μA at VR = 5.6 V), temperature coefficient (+2.5 to +5.3 mV/K), and SOD123F surface-mount compatibility with standard reflow profiles.
Technical Context
This device operates as a two-terminal voltage reference by exploiting controlled reverse-biased avalanche breakdown. Its 7.5 V nominal Zener voltage is specified at IZ = 5 mA with ±5 % tolerance, and exhibits a positive temperature coefficient of +2.5 to +5.3 mV/K over 25–150 °C, enabling predictable drift in bias networks.
The SOD123F package delivers 150 K/W junction-to-solder-point thermal resistance and supports 830 mW steady-state dissipation on FR4 PCB with 1 cm² cathode pad - critical for maintaining Tj ≤ 150 °C in compact power management layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.0 V to 7.9 V at IZ = 5 mA - defines regulated output range for precision reference use |
| Tolerance | ±5 % - determines worst-case voltage deviation in feedback or sensing paths |
| Differential Resistance (rdif) | ≤80 Ω - limits output impedance and load-regulation error under varying current |
| Reverse Current (IR) | ≤1 μA at VR = 5.6 V - ensures minimal leakage in high-impedance bias networks |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 layout |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - enables use as polarity protection or clamping diode in dual-role designs |
| Junction Temperature (Tj) | −65 °C to +150 °C - supports operation in industrial ambient environments without derating |
Pinout & Package
SOD123F plastic surface-mount package: 2-pin, flat lead, cathode marked by bar; dimensions 3.5 mm × 1.6 mm × 1.1 mm (L × W × H); optimized for automated placement and reflow soldering per IPC-7351B footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for orientation-sensitive assembly |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Power rating | 830 mW at Tamb ≤ 25 °C - enables regulation in space-constrained 3.3 V/5 V auxiliary rails without heatsinking |
| Voltage tolerance | ±5 % - balances cost and accuracy for non-critical reference applications like LED current setting |
| Thermal resistance | 150 K/W (junction-to-solder-point) - allows direct thermal coupling to copper pour for improved reliability |
| Leakage control | IR ≤ 1 μA at VR = 5.6 V - preserves battery life in always-on sensor bias circuits |
| Package footprint | SOD123F - compatible with high-density PCB layouts and standard pick-and-place equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C7V5,115 | Same SOD123F package and 7.5 V rating, but ±5 % tolerance per older BZT52C series; slightly higher rdif (≤100 Ω) | Identical functional role; minor increase in regulation error under load variation | Select when legacy BOM alignment or extended stock availability is prioritized over lowest rdif |
| MMSZ5236B-7-F | 7.5 V, ±5 %, SOD-123 package, 80 Ω rdif, but rated for only 500 mW Ptot and higher IR (≤5 μA at VR = 5.6 V) | Lower power headroom limits use in sustained 10 mA regulation; higher leakage reduces battery runtime | Choose only for cost-sensitive, low-duty-cycle applications where 500 mW suffices and leakage is not critical |
Compared with BZT52H-C7V5, the BZT52C7V5 offers identical form-factor and tolerance but trades 20 Ω higher differential resistance for broader legacy support, while MMSZ5236B-7-F sacrifices 330 mW power margin and 5× leakage performance to meet lower-cost sourcing targets.

FAQ
What is the maximum continuous reverse current the BZT52H-C7V5 can sustain?
The device is rated for 250 mA maximum forward current (IF), but as a Zener diode, its continuous reverse current is limited by power dissipation. At 7.5 V, the absolute maximum continuous Zener current is 110 mA (830 mW ÷ 7.5 V), assuming Tamb ≤ 25 °C and proper PCB thermal design per datasheet mounting conditions.
Does the BZT52H-C7V5 support automotive applications?
No. The BZT52H series is explicitly designated as non-automotive qualified per Nexperia's revision history (Rev. 7, Jan 2023). Automotive alternatives require the -Q suffix (e.g., BZT52H-C7V5-Q) and undergo AEC-Q101 stress testing - this part lacks those qualifications and is intended for industrial and commercial use only.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified SZ of +2.5 to +5.3 mV/K at IZ = 5 mA, the BZT52H-C7V5 exhibits a predictable positive drift: VZ increases ~15–32 mV across a 60 °C span (e.g., 25 °C to 85 °C). This must be factored into reference stability budgets - unlike compensated references, no internal compensation is provided.
Can the BZT52H-C7V5 be used in forward-bias applications?
Yes. Its forward voltage is ≤0.9 V at 10 mA, making it suitable for polarity protection or low-drop rectification in low-current signal paths. However, its 250 mA IF rating is significantly lower than dedicated rectifiers, so it should only be used in forward mode where current remains well below that limit and thermal rise is managed.
