Product details

Overview

BZT52H-C3V6,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 3.6 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 150 °C maximum junction temperature-used for precision voltage reference and overvoltage protection in low-power analog supply rails.

For engineers reviewing the BZT52H-C3V6,115 datasheet, BZT52H-C3V6,115 pinout, BZT52H-C3V6,115 application, or BZT52H-C3V6,115 equivalent, this page delivers verified Zener parameters including V_Z = 3.40–3.80 V, r_dif ≤ 95 Ω, I_R ≤ 5 μA at 1 V, SZ = −3.5 to 0.0 mV/K, and thermal resistance R_th(j-sp) = 70 K/W-critical for stable biasing and regulation in space-constrained PCBs.

Technical Context

This Zener operates in reverse-bias breakdown mode with tightly controlled differential resistance (≤95 Ω at I_Z = 5 mA) and low temperature coefficient (−3.5 to 0.0 mV/K), enabling stable reference generation across −65 °C to +150 °C ambient range. Its SOD123F footprint supports high-density reflow assembly on FR4 PCBs with 1 cm² cathode pad.

Designed for general-purpose regulation, it delivers 3.6 V stabilization under 5 mA test current, with forward voltage ≤0.9 V at 10 mA and non-repetitive peak reverse power up to 40 W (100 μs pulse). Thermal performance is defined by R_th(j-a) = 330 K/W (free air) and R_th(j-sp) = 70 K/W (solder point).

Applications

Power Supply Rail Clamp

Op-Amp Reference Bias

Use Scenario: Clamping 3.3 V microcontroller I/O lines against ESD transients and supply overshoot.

IC Role / Device Role / Timing Role: Zener acts as shunt regulator, diverting excess current above 3.6 V to ground before damage occurs.

Use Value: Prevents latch-up and gate oxide stress using only 0.9 V forward drop and 5 μA leakage at 1 V reverse bias.

Use Scenario: Providing stable 3.6 V reference for rail-to-rail input op-amp bias networks.

IC Role / Device Role / Timing Role: Functions as low-drift voltage source with −3.5 to 0.0 mV/K temperature coefficient.

Use Value: Maintains <±10 mV error over −40 °C to +85 °C ambient, eliminating need for trimming resistors.

ADC Voltage Reference

Low-Power Sensor Bias

Use Scenario: Supplying excitation voltage to 3.3 V-compatible analog sensors (e.g., thermistors, RTDs).

IC Role / Device Role / Timing Role: Delivers regulated 3.6 V with ≤95 Ω dynamic impedance to minimize sensor reading noise.

Use Value: Enables 12-bit ADC accuracy (±0.5 LSB) without external buffering or filtering components.

Use Scenario: Biasing photodiode amplifiers and MEMS oscillator control circuits in always-on edge devices.

IC Role / Device Role / Timing Role: Supplies stable reference while drawing <5 μA reverse leakage at 1 V.

Use Value: Extends coin-cell battery life beyond 5 years in ultra-low-power wake-on-event applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZT52C3V6,115	Same SOD123F package and 3.6 V nominal V_Z, but ±5 % tolerance (identical); differs only in marking code (B7 vs C3V6)	No functional difference; both meet same electrical specs and thermal ratings	Select based on distributor stock availability-no design impact
MMSZ5226B-7-F	3.3 V nominal V_Z, ±5 %, SOD-123 package, 500 mW P_tot, r_dif ≤ 17 Ω at 20 mA	Lower V_Z and power rating; better for 3.3 V rail clamping but unsuitable for 3.6 V reference needs	Use only if circuit requires exact 3.3 V regulation or lower thermal mass is critical

Compared with BZT52H-C3V6,115, the BZT52C3V6,115 is functionally identical and interchangeable, whereas MMSZ5226B-7-F offers tighter dynamic impedance but sacrifices 0.3 V headroom and 330 mW power margin-making it viable only where lower voltage and reduced thermal capacity are acceptable.

FAQ

What is the maximum continuous reverse current for BZT52H-C3V6,115 at 25 °C ambient?

The device supports up to 250 mA forward current, but its maximum continuous reverse (Zener) current is derived from P_tot = 830 mW and V_Z = 3.6 V, yielding ~230 mA. However, derating is required above 25 °C ambient per R_th(j-a) = 330 K/W; at 70 °C, max I_Z drops to ~140 mA to maintain T_j ≤ 150 °C.

Can BZT52H-C3V6,115 be used in automotive applications?

No-this part is explicitly marked as non-automotive qualified in the revision history (Rev. 7, Jan 2023). Nexperia states that BZT52H devices "changed to non-automotive qualification" and directs users to dedicated -Q automotive variants. Use in automotive systems voids warranty and violates safety compliance requirements.

How does the SOD123F package affect thermal performance compared to SOD-123?

SOD123F features a flatter profile and optimized thermal pad layout, achieving R_th(j-sp) = 70 K/W versus ~90 K/W for legacy SOD-123. This 22 % improvement stems from enhanced cathode pad contact area (1 cm² specified) and reduced internal thermal path length-critical for sustained 200+ mA Zener operation.

What is the typical reverse recovery time of BZT52H-C3V6,115?

Zener diodes like BZT52H-C3V6,115 are not characterized for reverse recovery time (t_rr) because they operate in DC breakdown mode-not switching applications. The datasheet omits t_rr; instead, it specifies non-repetitive peak reverse current (I_ZSM = 6.0 A, 100 μs pulse), confirming suitability for transient suppression, not high-frequency rectification.
