Product details
Overview
HZM15NB1TL-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 15.37 V to 16.01 V at 5 mA test current, with dynamic resistance of 40 Ω max, power dissipation of 200 mW, and operates within –55°C to +150°C storage range.
For engineers reviewing the HZM15NB1TL-E datasheet, HZM15NB1TL-E pinout, HZM15NB1TL-E application, or HZM15NB1TL-E equivalent, key selection criteria include its tight zener voltage tolerance (B1 grade), MPAK surface-mount package compatibility with high-density PCB layouts, low temperature coefficient near zero crossing (~0.02 mV/°C at ~15 V), and suitability for voltage reference, overvoltage protection, and biasing in industrial sensor interfaces and power supply feedback loops.
Technical Context
The HZM15NB1TL-E employs a silicon epitaxial planar junction structure optimized for stable reverse-bias breakdown with minimal leakage. Its zener voltage is specified at IZ = 5 mA, with reverse current limited to ≤2 μA at VR = 11.0 V - ensuring predictable turn-on behavior in regulation and clamping roles.
Thermal performance is defined by a maximum junction temperature of 150°C and a power derating curve (Fig.3) that reduces allowable dissipation linearly above 25°C ambient. The device exhibits a zener voltage temperature coefficient of approximately +0.02 mV/°C near 15 V, confirming minimal drift across industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.37 V to 16.01 V at IZ = 5 mA - defines precise regulation point for reference and clamp circuits |
| Dynamic Resistance (rd) | ≤40 Ω at IZ = 5 mA - ensures low output impedance and minimal load-induced voltage shift |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC or pulsed power handling in compact MPAK footprint |
| Reverse Current (IR) | ≤2 μA at VR = 11.0 V - guarantees low leakage before breakdown, critical for high-impedance bias networks |
| Junction Temperature (Tj) | 150°C maximum - enables reliable operation in thermally constrained industrial and automotive under-hood environments |
| Storage Temperature | –55°C to +150°C - supports wide-range logistics, reflow, and long-term field deployment without parametric shift |
| Temperature Coefficient | +0.02 mV/°C near 15 V - indicates near-zero drift region ideal for stable voltage references |
Pinout & Package

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 |
|---|---|---|---|
| MMSZ5245B-TP (Micro Commercial) | Zener voltage 15.0–16.2 V (±5%), Pd = 500 mW, SOD-123 package, rd = 30 Ω typical | Higher power rating but wider voltage tolerance and larger footprint - suitable when board space permits higher dissipation margin | Select when >200 mW continuous dissipation is required and ±5% VZ tolerance is acceptable |
| BZX84-C15 (Nexperia) | Zener voltage 14.3–15.7 V (±5%), Pd = 300 mW, SOT-23 package, rd = 30 Ω typical | Lower nominal VZ, same 3-pin SOT-23 footprint but no NC pin - requires redesign if NC isolation is critical for noise immunity | Select for cost-sensitive, non-isolated biasing where 15 V nominal (not 15.7 V) suffices and NC pin is unnecessary |
Compared with MMSZ5245B-TP and BZX84-C15, the HZM15NB1TL-E offers tighter B1-grade voltage tolerance (±2.1%) and a dedicated NC pin for improved noise rejection in sensitive analog nodes - making it preferred for precision reference and high-reliability industrial applications despite its 200 mW limit.

FAQ
What is the exact zener voltage range for HZM15NB1TL-E?
The HZM15NB1TL-E has a guaranteed zener voltage range of 15.37 V to 16.01 V when tested at IZ = 5 mA and Ta = 25°C. This B1-grade specification reflects ±2.1% tolerance around the nominal 15.7 V point, confirmed in Renesas' R07DS0358EJ0600 datasheet, Page 2. The HZM15NB1TL-E maintains this range across its qualified operating temperature span without recalibration.
Does HZM15NB1TL-E have a functional third pin?
No - Pin 1 of the HZM15NB1TL-E is explicitly designated "NC" (No Connect) in the official pin arrangement diagram (Page 1). It is electrically isolated and must remain unconnected in circuit layout to prevent unintended coupling or thermal stress. The functional terminals are Pin 2 (Anode) and Pin 3 (Cathode), which define the zener junction. This NC configuration is unique to the MPAK package and distinguishes HZM15NB1TL-E from standard 2-pin Zeners.
What is the maximum reverse current specification for HZM15NB1TL-E?
The HZM15NB1TL-E specifies a maximum reverse current (IR) of 2 μA at VR = 11.0 V, per the Electrical Characteristics table on Page 2 of the datasheet. This low leakage ensures minimal loading on high-impedance bias networks and preserves accuracy in precision reference applications. The value is measured under DC conditions and validated across the full storage temperature range (–55°C to +150°C).
Can HZM15NB1TL-E be used in automotive applications?
The HZM15NB1TL-E is rated for storage from –55°C to +150°C and junction operation up to 150°C, meeting under-hood thermal requirements. However, Renesas classifies the HZM-N Series as "Standard" quality grade - intended for industrial, office, and consumer equipment per their quality policy (Page 6). For automotive safety-critical functions, formal qualification per AEC-Q101 and manufacturer's written consent are required; the HZM15NB1TL-E alone does not constitute automotive-qualified status.
What is the thermal derating behavior of HZM15NB1TL-E?
The HZM15NB1TL-E follows a linear power derating curve starting at 200 mW at Ta = 25°C, decreasing to zero at Ta ≈ 150°C, as shown in Fig.3 (Page 5). Derating slope is approximately –1.7 mW/°C above 25°C ambient. This behavior assumes mounting on a standard 1.6 mm FR-4 PCB with 1.0 mm × 0.8 mm copper pad per terminal - actual thermal performance depends on PCB copper area and airflow. The HZM15NB1TL-E must be operated within this curve to maintain reliability and parameter stability.
