Product details
Overview
HZM36NBTR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 36 V (min 34.0 V, max 38.0 V), 2 mW reverse current test condition, 27 Ω dynamic resistance at 2 mA, 200 mW power dissipation, and MPAK surface-mount package.
For engineers reviewing the HZM36NBTR-E datasheet, HZM36NBTR-E pinout, HZM36NBTR-E application, or HZM36NBTR-E equivalent, this device serves as a stable, temperature-compensated voltage reference in power supply feedback loops, sensor biasing networks, and overvoltage protection clamping stages where tight voltage tolerance and low dynamic impedance are required.
Technical Context
The HZM36NBTR-E operates as a two-terminal shunt regulator, maintaining a stable output voltage across its cathode–anode terminals when reverse-biased above its breakdown threshold. Its zener voltage exhibits a positive temperature coefficient of approximately +0.07 mV/°C near 36 V, enabling predictable drift behavior in ambient-temperature-varying environments.
Designed for high-density PCB assembly, it uses a three-terminal MPAK (PLSP0003ZC-A) package with Pin 1 NC, Pin 2 anode, and Pin 3 cathode - supporting automated placement while isolating the unused terminal to minimize parasitic coupling in noise-sensitive references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines usable regulation range for feedback or clamp design |
| Dynamic Resistance (rd) | 90 Ω max at IZ = 2 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | 2 μA max at VR = 27 V - specifies leakage level below breakdown, critical for low-power standby operation |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating applies |
| Junction Temperature (Tj) | 150°C max - constrains operating ambient and board-level thermal design for reliability |
| Package | MPAK (PLSP0003ZC-A) - 3-pin SMT package with 1.0 mm × 1.3 mm footprint, optimized for high-density layout |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A, Renesas code MPAK(D)V) measures 1.0 mm × 1.3 mm × 0.55 mm (L × W × H), with gull-wing leads and exposed pad not electrically connected. Pin 1 is NC (no internal connection), Pin 2 is anode, Pin 3 is cathode - top-view orientation matches standard SMT placement vision systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Internally unconnected; must be left floating or grounded per layout best practice - no electrical function |
| 2 | Anode | Connected to lower-potential node in shunt configuration; current enters here during reverse conduction |
| 3 | Cathode | Connected to higher-potential node; regulated voltage appears at this terminal relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Grade B Zener Tolerance | ±5.6% total variation (34.0–38.0 V) - enables cost-effective selection without binning for non-critical references |
| Pulse-tested Zener Parameters | Specified using 40 ms pulse width - ensures parameter stability under transient overload conditions |
| Low-Temperature-Coefficient Operation | +0.07 mV/°C near 36 V - supports predictable drift compensation in industrial temperature ranges (–25°C to +85°C) |
| High-Density MPAK Packaging | 0.011 g mass, 1.0 mm × 1.3 mm footprint - reduces board area by >40% vs. SOD-323 in space-constrained designs |

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, SOT-23 package, 350 mW Pd, 90 Ω rd | Higher power rating but larger footprint; requires different land pattern and stencil | Select when higher surge energy handling is needed and board space allows SOT-23 |
| MMSZ5245B-TP | 36 V nominal, ±5% tolerance, SOD-123 package, 500 mW Pd, 100 Ω rd | Higher power and slightly higher dynamic resistance; incompatible pinout and thermal profile | Choose for legacy designs using SOD-123 or where 500 mW derating margin is mandatory |
Compared with BZX84-C36LT1G and MMSZ5245B-TP, the HZM36NBTR-E offers the smallest PCB footprint (MPAK), lowest thermal mass for fast transient response, and tighter zener voltage consistency within Renesas' Grade B binning - making it optimal for miniaturized industrial and automotive control modules where layout density and thermal predictability are prioritized.

FAQ
What is the zener voltage tolerance for HZM36NBTR-E?
The HZM36NBTR-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 value. This Grade B specification is verified per Renesas preliminary datasheet R07DS0358EJ0600 Rev.6.00 and applies to all units shipped under this part number.
Does HZM36NBTR-E have a pin 1 functional connection?
No - Pin 1 of the HZM36NBTR-E is designated NC (No Connection) and is internally unconnected. It must remain unbonded and may be left floating or tied to ground for mechanical stability, but it contributes no electrical function in the HZM36NBTR-E circuit operation.
What is the maximum power dissipation of HZM36NBTR-E at 70°C ambient?
Per Figure 3 in the HZM-N Series datasheet, the HZM36NBTR-E's power dissipation derates linearly from 200 mW at 25°C to approximately 120 mW at 70°C ambient temperature. This derating is defined by the thermal resistance and package construction of the MPAK (PLSP0003ZC-A) housing.
Is HZM36NBTR-E RoHS compliant and lead-free?
Yes - HZM36NBTR-E meets EU RoHS Directive requirements and is manufactured with lead-free terminations. Renesas confirms compliance in its environmental documentation, and the device carries appropriate marking per JEDEC standards for lead-free MPAK packaging.
How does the temperature coefficient of HZM36NBTR-E affect long-term stability?
The HZM36NBTR-E exhibits a positive temperature coefficient of approximately +0.07 mV/°C near 36 V, meaning its zener voltage increases by ~2.5 mV over a 35°C rise (e.g., 25°C to 60°C). This predictable drift enables first-order compensation in reference circuits and is documented in Figure 2 of the HZM-N Series datasheet.
