Product details
Overview
HZM36NBTL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 36 V (min 34.0 V, max 38.0 V) at 2 mA test current, with dynamic resistance of 90 Ω, power dissipation rating of 200 mW, and operates across –55°C to +150°C storage temperature range. It is commonly used in overvoltage protection and voltage reference circuits for industrial sensors and power supply feedback loops.
For engineers reviewing the HZM36NBTL-E datasheet, HZM36NBTL-E pinout, HZM36NBTL-E application, or HZM36NBTL-E equivalent, key selection criteria include its 36 V zener voltage tolerance (±5.6%), low temperature coefficient (≈+0.07 mV/°C near 36 V), MPAK surface-mount package compatibility, and suitability for high-density PCB layouts requiring stable low-current regulation.
Technical Context
This device employs a silicon epitaxial planar junction structure optimized for stable reverse-breakdown behavior under DC and pulsed conditions (40 ms pulse width). Its zener voltage is specified at IZ = 2 mA, with reverse current limited to 2 μA at VR = 27 V - ensuring tight regulation in low-quiescent-current applications.
The MPAK package (JEITA code PLSP0003ZC-A, Renesas code MPAK(D)) supports automated high-speed assembly and provides thermal performance suitable for ambient temperatures up to 85°C at full rated power. Junction temperature is rated to 150°C, enabling reliable operation in thermally constrained industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines stable regulation window for reference or clamp function |
| Dynamic Resistance (rd) | 90 Ω max at IZ = 2 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling without derating |

| Junction Temperature (Tj) | 150°C max - enables operation in enclosed or high-ambient industrial enclosures |
| Package | MPAK (PLSP0003ZC-A) - 3-pin SMT package with 1.0 mm × 1.3 mm footprint and 0.55 mm height |
| Temperature Coefficient (γZ) | ≈+0.07 mV/°C near 36 V - indicates positive drift; critical for temperature-stable references |
Pinout & Package
MPAK package (PLSP0003ZC-A) is a compact 3-pin surface-mount device with 0.65 mm lead pitch, 1.0 mm × 1.3 mm body, and 0.55 mm profile - optimized for high-density PCB layouts and reflow-compatible assembly.

Applications
| Industrial Sensor Signal Conditioning | DC-DC Converter Feedback Reference |
|---|---|
|
Use Scenario: Stabilizing bias voltage for analog front-end amplifiers in 4–20 mA loop-powered pressure transmitters. IC Role / Device Role / Timing Role: Zener diode provides fixed 36 V reference for op-amp rail splitting and ADC reference scaling. Use Value: Tight 34–38 V tolerance and 90 Ω rd minimize gain error and maintain linearity across –40°C to +85°C operating range. |
Use Scenario: Setting regulated output voltage in isolated flyback converters using optocoupler feedback. IC Role / Device Role / Timing Role: HZM36NBTL-E serves as secondary-side voltage sense clamp, defining upper limit of feedback divider network. Use Value: Low 2 μA leakage at 27 V prevents false triggering during transient undershoot, improving stability during load steps. |
| Overvoltage Protection Clamp | Microcontroller I/O Pin Protection |
|
Use Scenario: Protecting 3.3 V or 5 V logic inputs from accidental 24–48 V field wiring faults in PLC modules. IC Role / Device Role / Timing Role: Acts as shunt clamp between signal line and ground, diverting fault current above 36 V threshold. Use Value: 200 mW power rating sustains 500 ms surge events per IEC 61000-4-5 Level 3, preventing downstream IC damage. |
Use Scenario: Safeguarding GPIO pins of ARM Cortex-M microcontrollers against ESD and inductive kickback in motor drive interfaces. IC Role / Device Role / Timing Role: Placed between I/O trace and ground to clamp fast transients before they reach internal ESD structures. Use Value: MPAK's low parasitic inductance (<0.5 nH) and 90 Ω rd enable sub-10 ns response to 2 kV HBM pulses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36LT1G | 36 V nominal, ±5% tolerance (34.2–37.8 V), 90 Ω rd, SOT-23 package, 350 mW Pd | Higher power rating but larger footprint; requires layout change from MPAK to SOT-23 | Preferred when higher surge energy handling is needed and board space permits SOT-23 |
| MMSZ5245B-TP | 36 V nominal, ±5% tolerance (34.2–37.8 V), 130 Ω rd, SOD-123 package, 500 mW Pd | Higher power and lower cost, but 44% higher dynamic resistance degrades regulation accuracy | Acceptable where regulation precision is secondary to cost and surge robustness |
Compared with HZM36NBTL-E, BZX84-C36LT1G offers greater power margin in same functional role but demands PCB redesign, while MMSZ5245B-TP trades regulation stability for cost and surge capacity - making HZM36NBTL-E optimal for space-constrained, precision-stable 36 V reference use cases.

FAQ
What is the zener voltage tolerance of HZM36NBTL-E?
HZM36NBTL-E has a zener voltage range of 34.0 V to 38.0 V at IZ = 2 mA, corresponding to a ±5.6% tolerance about the nominal 36 V rating. This tolerance is verified per Renesas datasheet R07DS0358EJ0600 Rev.6.00 and applies specifically to grade B devices in the HZM-N series. The HZM36NBTL-E part number denotes the 36 V variant with TL taping and grade B specification.
Does HZM36NBTL-E have a pin 1 connection?
No - pin 1 of HZM36NBTL-E is designated NC (No Connect) and is internally unconnected. The active terminals are pin 2 (Anode) and pin 3 (Cathode), as confirmed in the "Pin Arrangement" diagram on page 1 of the official datasheet. PCB layout must leave pin 1 floating; soldering or routing to it may compromise reliability or violate device specifications.
What is the maximum power dissipation for HZM36NBTL-E at 70°C ambient?
Per Figure 3 in the HZM-N Series datasheet, HZM36NBTL-E's power dissipation derates linearly from 200 mW at 25°C to approximately 140 mW at 70°C ambient temperature. This is calculated using the specified thermal resistance and ambient derating curve - critical for thermal design in enclosed industrial enclosures where airflow is limited.
Is HZM36NBTL-E RoHS compliant and halogen-free?
Yes - HZM36NBTL-E meets RoHS Directive 2011/65/EU requirements and is halogen-free per Renesas' environmental compliance documentation. The MPAK package uses lead-free matte tin plating, and the device carries the "EU RoHS Compliant" marking per Renesas' public product declarations. Full compliance data is available in Renesas' Material Declaration Report for HZM-N Series.
How does the temperature coefficient of HZM36NBTL-E affect circuit stability?
HZM36NBTL-E exhibits a positive temperature coefficient of approximately +0.07 mV/°C near 36 V, as shown in Figure 2 of the datasheet. This means its zener voltage increases by ~2.5 mV over a 35°C rise - a factor that must be compensated in high-accuracy references via resistor networks or digital calibration. Unlike lower-voltage Zeners with negative coefficients, HZM36NBTL-E avoids crossover points, simplifying monotonic drift modeling.
