Product details
Overview
HZM3.6NB2TL-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for voltage stabilization in low-power analog and digital supply rails, featuring a nominal zener voltage of 3.6 V (3.55–3.80 V), 10 µA maximum reverse current at 1.0 V, and 130 Ω dynamic resistance at 5 mA test current - deployed in precision reference circuits, sensor biasing, and microcontroller reset supervision.
For engineers reviewing the HZM3.6NB2TL-E datasheet, HZM3.6NB2TL-E pinout, HZM3.6NB2TL-E application, or HZM3.6NB2TL-E equivalent, key selection criteria include its MPAK surface-mount package, ±5% zener voltage tolerance (Grade B2), 200 mW power dissipation, junction temperature limit of 150°C, and suitability for high-density PCB layouts requiring stable low-voltage regulation.
Technical Context
The HZM3.6NB2TL-E operates as a two-terminal shunt regulator with fixed breakdown behavior governed by controlled avalanche and Zener mechanisms. Its electrical characteristics are specified at 25°C ambient with pulsed test conditions (Pw = 40 ms) to minimize self-heating effects during measurement.
It exhibits a positive zener voltage temperature coefficient of approximately +0.03 mV/°C near 3.6 V, enabling predictable drift compensation in temperature-sensitive references. The device is rated for storage between –55°C and +150°C and requires no external biasing circuitry beyond series current limiting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.55–3.80 V at IZ = 5 mA - defines stable regulation point for 3.3 V system references and LDO feedback networks. |
| Reverse Current (IR) | ≤10 µA at VR = 1.0 V - ensures minimal leakage in standby mode for battery-powered sensors. |
| Dynamic Resistance (rd) | 130 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity in shunt configurations. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous current limit (~55 mA at 3.6 V) before thermal derating applies. |
| Junction Temperature (Tj) | 150°C maximum - constrains operating ambient and PCB copper area requirements for thermal management. |
| Package | MPAK (PLSP0003ZC-A) - 3-pin SMT package with 1.0 mm × 1.3 mm footprint, optimized for automated placement and reflow. |
| Zener Grade | B2 - specifies tighter VZ tolerance (±2.8%) versus Grade B (±5.6%), critical for calibration-grade references. |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A) with 1.0 mm × 1.3 mm body, 0.35–0.5 mm lead width, and 2.2–3.0 mm terminal pitch. Designed for high-density surface mounting and compatible with standard 0805 footprint land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no routing or soldering required. |
| 2 | Anode | Current entry point during forward bias; tied to lower-potential rail in shunt regulator configuration. |
| 3 | Cathode | Current exit point during reverse breakdown; connected to regulated voltage node and series resistor input. |
Key Features
| Feature | Design Value |
|---|---|

| Low dynamic impedance | 130 Ω supports tight regulation under varying load currents up to ~10 mA without external buffering. |
| Grade B2 tolerance | ±2.8% VZ spec reduces calibration overhead in factory-trimmed instrumentation front-ends. |
| MPAK surface-mount package | 0.35 mm lead width and 2.2 mm terminal pitch allow placement on 0.5 mm pitch PCBs with standard SPI feeders. |
| High-temperature operation | Rated to 150°C junction temperature supports use in automotive under-hood modules and industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ4684T1G | 3.68 V nominal VZ, ±5% tolerance, SOD-123 package, 500 mW Pd | Higher power rating allows >100 mA surge current; larger footprint limits ultra-dense layouts | Select when higher surge immunity or legacy SOD-123 footprint compatibility is required |
| BZX84-C3V6 | 3.6 V nominal VZ, ±5% tolerance, SOT-23 package, 300 mW Pd, 90 Ω rd | Lower dynamic resistance improves load regulation; 3-pin SOT-23 requires cathode/anode assignment verification | Select when tighter regulation under variable load is prioritized over Grade B2 tolerance |
Compared with MMSZ4684T1G and BZX84-C3V6, the HZM3.6NB2TL-E offers tighter VZ tolerance (B2 grade), smaller MPAK footprint, and lower leakage - making it optimal for space-constrained, precision-biased circuits where absolute voltage accuracy outweighs raw power handling.

FAQ
What is the zener voltage tolerance for HZM3.6NB2TL-E?
The HZM3.6NB2TL-E is graded B2, specifying a zener voltage range of 3.55 V to 3.80 V at 5 mA test current - corresponding to ±2.8% tolerance around the nominal 3.6 V value. This tighter tolerance than Grade B (±5.6%) makes HZM3.6NB2TL-E suitable for applications requiring higher initial accuracy without post-production trimming.
Can HZM3.6NB2TL-E replace a standard 3.3 V Zener diode in microcontroller reset circuits?
Yes - the HZM3.6NB2TL-E provides a stable 3.6 V breakdown that can be used with a resistive divider to generate a precise 3.3 V threshold for reset ICs or internal brown-out detectors. Its low 10 µA leakage at 1.0 V ensures minimal impact on standby current, and its MPAK package fits modern high-density PCB layouts where HZM3.6NB2TL-E is often preferred over larger SOD-123 alternatives.
What is the maximum continuous power dissipation for HZM3.6NB2TL-E at 70°C ambient?
Per Figure 3 in the datasheet, the HZM3.6NB2TL-E's power dissipation derates linearly from 200 mW at 25°C to approximately 140 mW at 70°C ambient temperature. This corresponds to a maximum continuous zener current of ~39 mA at 3.6 V, assuming no additional board-level heatsinking - a value confirmed by the device's thermal resistance and ambient derating curve.
Is Pin 1 of HZM3.6NB2TL-E electrically connected internally?
No - Pin 1 of the HZM3.6NB2TL-E is designated NC (No Connect) and is not bonded to any internal die structure. It must remain unconnected on the PCB; routing or soldering to Pin 1 may cause mechanical stress or unintended parasitic coupling. The functional terminals are Pin 2 (Anode) and Pin 3 (Cathode), as confirmed in the top-view pin arrangement diagram.
Does HZM3.6NB2TL-E meet RoHS and REACH compliance requirements?
Yes - HZM3.6NB2TL-E complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed by Renesas Electronics' material declarations and product change notifications. The device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits, and is marked with standard RoHS-compliant packaging labels per the datasheet environmental notice.
