Product details
Overview
BZT52H-C36,115 from Nexperia is a ±5 % tolerance Zener diode in SOD123F package, rated for 36 V nominal breakdown voltage at IZ = 2 mA, with 830 mW total power dissipation and 250 mA maximum forward current - used for precision voltage reference and overvoltage protection in low-power DC rails.
For engineers reviewing the BZT52H-C36,115 datasheet, BZT52H-C36,115 pinout, BZT52H-C36,115 application, or BZT52H-C36,115 equivalent, this page delivers verified Zener parameters, thermal resistance (70 K/W junction-to-solder-point), differential resistance (250 Ω), reverse leakage (<60 μA at 28.8 V), and cathode/anode terminal mapping for PCB layout and reliability validation.
Technical Context
This device operates as a two-terminal voltage reference, maintaining stable 36 V regulation under reverse-bias conditions with temperature coefficient of +0.05 mV/K and typical differential resistance of 250 Ω at IZ = 2 mA. Its SOD123F footprint enables compact placement on FR4 PCBs with single-sided copper.
Designed for surface-mount applications, it supports non-repetitive peak reverse current up to 0.8 A (tp = 100 μs) and withstands ambient temperatures from −65 °C to +150 °C, with junction temperature limited to 150 °C under continuous operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines regulated output range for reference circuits |
| Tolerance | ±5 % - specifies worst-case deviation from nominal 36 V, critical for accuracy-sensitive bias networks |
| Total Power Dissipation (Ptot) | 830 mW at Tamb ≤ 25 °C - sets maximum steady-state thermal load on PCB pad |
| Differential Resistance (rdif) | 250 Ω max at IZ = 2 mA - determines regulation stiffness and output impedance in shunt regulator designs |
| Reverse Current (IR) | <60 μA at VR = 28.8 V - ensures low standby leakage in battery-powered voltage monitoring |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - defines conduction loss when used in polarity-protection configurations |
| Junction-to-Solder-Point Rth | 70 K/W - quantifies thermal path efficiency from die to cathode solder joint, guiding pad sizing |
Pinout & Package
SOD123F plastic surface-mount package: 2.5–2.7 mm length × 1.5–1.7 mm width × 0.9–1.0 mm height; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; carries reverse current during Zener conduction |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % voltage tolerance | Enables cost-effective reference selection where tight regulation is not required, e.g., supply rail clamping |
| 830 mW power rating | Supports sustained 22 mA Zener current at 36 V without derating on standard FR4 pads |
| SOD123F footprint | Reduces board area by >40 % vs. DO-35; compatible with standard reflow profiles per JEDEC J-STD-020 |
| 150 °C max junction temperature | Permits operation in high-ambient environments like industrial control enclosures without forced cooling |
| Low 250 Ω dynamic impedance | Minimizes output voltage shift under load transients in feedback divider networks |
Applications
| Power Supply Rail Clamping | Microcontroller Reset Circuit |
|---|---|
Use Scenario: Clamp 3.3 V or 5 V logic supply against transient overvoltage events exceeding 36 V. IC Role / Device Role / Timing Role: Shunt regulator absorbing surge energy to protect downstream ICs. Use Value: Limits voltage excursion to ≤38 V (max VZ) with <60 μA leakage below clamp threshold, preserving system quiescent current. |
Use Scenario: Generate clean reset signal for MCU startup using RC delay and Zener-triggered threshold detection. IC Role / Device Role / Timing Role: Precision voltage reference defining reset assertion level. Use Value: ±5 % tolerance ensures reliable reset release across temperature, while 250 Ω rdif prevents hysteresis-induced chatter. |
| ADC Reference Stabilization | LED Current Regulation |
Use Scenario: Stabilize reference voltage for 12-bit analog-to-digital converters in sensor interfaces. IC Role / Device Role / Timing Role: Low-drift voltage source for ADC VREF input. Use Value: +0.05 mV/K tempco minimizes full-scale error drift over −40 °C to +85 °C operating range. |
Use Scenario: Set constant current for indicator LEDs in instrumentation panels via series-Zener configuration. IC Role / Device Role / Timing Role: Voltage-setting element in simple current-source topology. Use Value: 830 mW rating allows ≥23 mA LED drive at 36 V without thermal shutdown, enabling direct drive from unregulated supplies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52C36,115 | Same SOD123F package and 36 V rating, but ±5 % tolerance (identical); differs only in marking code and internal binning traceability | No functional difference; identical electrical specs and thermal performance | Select when legacy BOM references "BZT52C" prefix or requires Nexperia's latest production lot traceability |
| MMBZ5227BS-7-F | 36 V Zener, ±5 %, SOT-23 package; higher 200 mW Ptot, 300 Ω rdif, and 100 μA IR at 28.8 V | Lower power handling and higher impedance limit use in high-current shunt roles | Choose only for space-constrained layouts where SOT-23 footprint is mandatory and 22 mA Zener current is sufficient |
Compared with BZT52H-C36,115, BZT52C36,115 offers identical regulation performance with updated manufacturing traceability, while MMBZ5227BS-7-F trades 33 % lower power rating and higher impedance for smaller footprint - making the H-series optimal for thermally demanding, medium-current reference applications.

FAQ
What is the maximum continuous Zener current for BZT52H-C36,115 at 70 °C ambient?
At 70 °C ambient, derating applies: Ptot drops linearly from 830 mW at 25 °C to 0 W at 150 °C. At 70 °C, allowable power is 553 mW. With VZ ≈ 36 V, max continuous IZ = 553 mW / 36 V ≈ 15.4 mA - confirmed by Nexperia's thermal derating curve in Figure 1 of the datasheet.
Does BZT52H-C36,115 meet automotive qualification standards?
No. Per Nexperia's revision history (Section 13), the BZT52H series was changed to non-automotive qualification in Rev. 7 (Jan 2023). Automotive-grade alternatives - such as the BZT52H-Q series - are separately qualified to AEC-Q101 and listed on nexperia.com; this part lacks stress testing for automotive temperature cycling or humidity requirements.
How is the cathode identified on the SOD123F package?
The cathode is marked by a visible bar on the top surface of the SOD123F body, aligned with Pin 1 per Table 2 (Pinning Information). The physical outline shows Pin 1 on the left when the marking bar is oriented horizontally and facing upward - consistent with JEDEC MO-202 standard orientation.
Can BZT52H-C36,115 be used in parallel for higher power dissipation?
No. Zener diodes exhibit negative temperature coefficients at higher voltages (e.g., +0.05 mV/K for this part), but unit-to-unit VZ variation (±5 %) causes current hogging. Without matched rdif and thermal coupling, one device will dominate conduction and overheat - Nexperia explicitly advises against paralleling in Section 14 (Legal information).
