Product details
Overview
HZM10NB2TL-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 10.11–10.55 V at 5 mA, with dynamic resistance of 7.0 Ω, power dissipation up to 200 mW, and operates within –55°C to +150°C storage temperature range - commonly used in voltage regulation for sensor signal conditioning and microcontroller reference supplies.
For engineers reviewing the HZM10NB2TL-E datasheet, HZM10NB2TL-E pinout, HZM10NB2TL-E application, or HZM10NB2TL-E equivalent, key selection criteria include zener voltage tolerance (±2.2% at 10.33 V nominal), low dynamic impedance for stable regulation under varying load, MPAK surface-mount package compatibility with high-density PCB layouts, and thermal stability across industrial ambient conditions.
Technical Context
The HZM10NB2TL-E employs a silicon epitaxial planar junction structure optimized for tight zener voltage control and low temperature coefficient (≈+0.045 mV/°C near 10 V). Its design targets stable DC reference generation where low noise and minimal drift are critical.
It operates in reverse-bias breakdown mode with specified test current IZ = 5 mA, reverse current IR ≤ 2 μA at VR = 7.0 V, and exhibits thermal resistance characteristics suited for operation on standard FR-4 PCBs with minimal copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.11–10.55 V at IZ = 5 mA - defines precise regulation point for feedback loops or reference rails. |
| Dynamic Resistance (rd) | 7.0 Ω max at IZ = 5 mA - ensures minimal output voltage variation under load transients. |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating applies. |
| Reverse Current (IR) | ≤2 μA at VR = 7.0 V - guarantees low leakage in standby or high-impedance bias networks. |
| Junction Temperature (Tj) | 150°C max - supports reliable operation in enclosed industrial enclosures without forced cooling. |
| Temperature Coefficient (γZ) | +0.045 mV/°C near 10 V - enables predictable drift compensation in temperature-sensitive references. |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), surface-mount, 3-terminal plastic package with 1.0 mm × 1.3 mm footprint and 0.55 mm terminal pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected; must remain floating - no routing or soldering required. |
| 2 | Anode | Connected to lower-potential side of circuit; reverse-biased during regulation operation. |

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-C10LT1G | Zener voltage 9.4–10.6 V (±5%), 300 mW Pd, SOT-23 package, rd = 20 Ω. | Higher power rating but looser tolerance and higher impedance - suitable where cost and board space outweigh precision needs. | Select when budget constraints dominate and ±5% regulation is acceptable in non-critical biasing. |
| MMSZ5240B-TP | Zener voltage 10.0–10.6 V (±5%), 500 mW Pd, SOD-123 package, rd = 17 Ω. | Higher power and larger footprint - better for higher-current shunt regulation but less stable under light loads. | Prefer for designs requiring >200 mW dissipation or legacy SOD-123 layout compatibility. |
Compared with BZX84-C10LT1G and MMSZ5240B-TP, the HZM10NB2TL-E offers tighter voltage tolerance (±2.2% vs. ±5%), lower dynamic resistance (7.0 Ω vs. ≥17 Ω), and smaller MPAK footprint - making it optimal for precision, space-constrained, low-current reference applications.

FAQ
What is the exact zener voltage range for HZM10NB2TL-E?
The HZM10NB2TL-E has a guaranteed zener voltage range of 10.11 V to 10.55 V when tested at IZ = 5 mA and Ta = 25°C. This corresponds to Grade B2 specification, offering ±2.2% tolerance around the nominal 10.33 V value - confirmed in Renesas datasheet R07DS0358EJ0600, page 3.
Does HZM10NB2TL-E have a pin 1 connection?
No - pin 1 of the HZM10NB2TL-E is designated NC (No Connect) and is internally unconnected. The functional terminals are pin 2 (Anode) and pin 3 (Cathode), as shown in the top-view pin arrangement diagram on page 1 of the Renesas datasheet. Leaving pin 1 unconnected is mandatory for proper operation.
What is the maximum reverse current for HZM10NB2TL-E at 7.0 V?
The maximum reverse current (IR) for HZM10NB2TL-E is 2 μA when measured at VR = 7.0 V and Ta = 25°C. This low leakage supports energy-efficient designs such as battery-powered monitors and high-impedance bias networks, as specified in the Electrical Characteristics table on page 3 of the official datasheet.
Can HZM10NB2TL-E be used in place of HZM10NBL-E?
No - HZM10NB2TL-E and HZM10NBL-E are not interchangeable. HZM10NB2TL-E is Grade B2 (10.11–10.55 V), while HZM10NBL-E is Grade B (10.11–10.55 V only for HZM10N, but L-grade denotes different taping and marking; actual B-grade tolerance is wider at ±5%). The "B2" suffix in HZM10NB2TL-E indicates tighter binning, and substitution requires verification against circuit tolerance requirements.
What is the thermal resistance characteristic of HZM10NB2TL-E?
The HZM10NB2TL-E does not specify junction-to-ambient thermal resistance (RθJA) directly, but its power derating curve (Fig.3, page 5) shows linear reduction from 200 mW at 25°C to 0 mW at ~150°C ambient. On standard FR-4 with minimal copper, typical RθJA is ≈625°C/W - meaning a 100 mW dissipation raises junction temperature by ~62.5°C above ambient, well within the 150°C Tj limit.
