Product details
Overview
1N6152 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection of 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and ultra-low 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the 1N6152 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, validated DFN-6 pin mapping, real-world use cases in USB PD and load switch protection, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The 1N6152 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown - enabling near-constant clamping voltage across 24–40A and −40°C to +125°C. Unlike conventional TVS diodes, its clamping behavior is governed by RDS(on) collapse rather than fixed dynamic resistance.
It operates as a single-line bidirectional protector with three parallel input terminals (Pins 4–6) and three ground terminals (Pins 1–3), requiring all six pins to be connected for full 40A surge rating. Its 175pF junction capacitance at 22V and 1MHz is optimized for DC bus and low-speed signal line protection - not high-speed data lanes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - defines maximum continuous DC or RMS operating voltage on protected line without leakage or degradation. |
| Clamping Voltage | 27.5–28V at 40A (8/20μs + 1.2/50μs combo wave, RS = 2Ω) - ensures downstream 24V-rated ICs (e.g., USB PD controllers) remain below damage threshold during surge. |
| Peak Pulse Current | 40A (8/20μs) - supports compliance with IEC 61000-4-5 Level 4 (±1kV, RS = 42Ω, CS = 0.5μF) on unsymmetrical lines. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD immunity requirements without derating. |
| Dynamic Resistance | 20mΩ (measured 1–40A, 8/20μs) - enables flat clamping curve and minimal voltage rise under increasing surge current. |
| Junction Capacitance | 175pF at 22V, 1MHz - suitable for power rails and low-speed control lines; not intended for USB SS, PCIe, or HDMI interfaces. |
Pinout & Package
1N6152 is housed in a Pb-free, RoHS-compliant DFN package measuring 1.6mm × 1.6mm × 0.55mm with 6 leads and UL 94V-0 molding compound. The package includes an exposed thermal pad (not electrically active) and laser-marked "T22" code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pins 1, 2, 3 | GND | Common ground return path for surge current; all three must be soldered to maximize current sharing and minimize parasitic inductance. |
| Pins 4, 5, 6 | IN | Parallel-connected input terminals tied to protected bus (e.g., VBUS in USB PD); all three required to achieve rated 40A capability. |
Key Features
| Feature | Design Value |
|---|---|
| Constant-clamp architecture | Clamping voltage remains stable (27.5–28V) across full 24–40A range and −40°C to +125°C - eliminates thermal derating uncertainty vs. TVS diodes. |
| FET-based shunt topology | Surge energy diverted through low-RDS(on) channel instead of PN-junction dissipation - improves reliability and lifetime under repeated transients. |
| Low dynamic resistance | 20mΩ enables <1V additional drop beyond trigger voltage under 40A - critical for protecting 24V-tolerant ICs with narrow overvoltage margins. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 100kHz & 5kHz bursts) - protects against repetitive switching noise in industrial motor drives and PLC I/O modules. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD profiles against lightning-induced surges and connector hot-plug ESD. IC Role / Device Role / Timing Role: Primary front-end EOS suppressor placed between connector and USB PD controller or load switch IC. Use Value: Maintains 27.5–28V clamping at 40A - stays below 29V damage threshold of common PD controllers (e.g., STUSB4500, TUSB7320) even at 125°C ambient. |
Use Scenario: Shielding input pins of industrial-grade load switches (e.g., HS2950P, TPS25982) from EOS events in remote meters, robotics, and factory automation equipment. IC Role / Device Role / Timing Role: Standalone transient shunt placed directly at load switch VIN pin to prevent gate oxide rupture or internal FET avalanche failure. Use Value: Limits voltage seen by load switch's internal high-side FET to ≤28V during ±1kV IEC 61000-4-5 surges - avoids latch-up or permanent parametric shift. |
| IoT Device Power Rail Protection | Storage Device DC Bus Protection |
Use Scenario: Securing 22V-rated power inputs of battery-powered IoT gateways and edge sensors exposed to field ESD and induced surges via long cables or metal enclosures. IC Role / Device Role / Timing Role: Single-component solution replacing multi-diode TVS arrays to reduce BOM count and PCB area in space-constrained designs. Use Value: 1.6mm × 1.6mm footprint saves >60% board area vs. legacy SOD-123 or SMA TVS devices while delivering superior clamping stability. |
Use Scenario: Safeguarding 22V auxiliary rails in NVMe SSD enclosures and enterprise HDD backplanes subjected to system-level ESD and power rail coupling. IC Role / Device Role / Timing Role: Secondary protection stage after bulk filtering, positioned upstream of DC-DC converters and PMICs. Use Value: 130–600nA reverse leakage at 22V ensures negligible standby current drain - critical for always-on storage subsystems with tight quiescent power budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P | Same die, identical specs, and pinout - direct manufacturer-recommended replacement for 1N6152; marked "T22" with date code. | Identical use cases: USB PD, load switch, industrial 22V bus protection. | Select TDS2211P when sourcing from Semtech's official distribution channel or requiring traceable lot documentation. |
| SM712-01HTG | TVS diode array (SOT-23), 12V working voltage, 300W peak power, 25V clamping at 10A - lacks constant-clamp FET architecture and temperature-stable performance. | Limited to lower-voltage (≤15V) applications; unsuitable for 22V USB PD due to higher clamping and thermal drift. | Choose SM712-01HTG only for cost-sensitive, non-PD 12V systems where 27V clamping margin is acceptable. |
Compared with 1N6152, TDS2211P offers identical electrical and mechanical performance with full documentation traceability, while SM712-01HTG provides lower-cost TVS protection at reduced voltage rating and degraded clamping stability - making it unsuitable for 22V USB PD or high-temperature industrial deployments.

FAQ
What is the exact package type and dimensions of the 1N6152?
The 1N6152 uses a 6-lead DFN package measuring 1.6mm × 1.6mm × 0.55mm with exposed pad (non-electrical). Pin 1 is marked by a laser dot; terminals are grouped as Pins 1–3 (GND) and Pins 4–6 (IN). All six pins must be soldered to achieve full 40A surge rating - partial connection degrades performance.
Does the 1N6152 meet IEC 61000-4-5 Level 4 surge immunity?
Yes, the 1N6152 is rated for ±1kV (1.2/50μs voltage, 8/20μs current, RS = 42Ω, CS = 0.5μF) on unsymmetrical lines per IEC 61000-4-5, supported by its 40A peak pulse current (8/20μs) and 27.5–28V clamping voltage. This meets Level 4 requirements for industrial environments.
How does the 1N6152 differ from standard TVS diodes in clamping behavior?
Unlike TVS diodes whose clamping voltage rises linearly with current (VC = VBR + IPP × RDYN), the 1N6152 uses a triggered FET shunt that maintains ~27.5–28V clamping from 24A to 40A and across −40°C to +125°C - eliminating thermal derating uncertainty and improving protection predictability.
Can the 1N6152 be used on high-speed data lines like USB SuperSpeed?
No, the 1N6152 is not suitable for USB SuperSpeed (SS), PCIe, or HDMI data lanes due to its 175pF junction capacitance at 22V. It is designed exclusively for DC power rails and low-speed control lines. For SS lines, Semtech recommends RClamp3371ZC (<0.25pF) alongside the 1N6152.
What is the maximum operating temperature range for the 1N6152?
The 1N6152 is specified for continuous operation from −40°C to +125°C ambient temperature. Its clamping voltage remains stable across this full range - confirmed by characterization data showing <0.5V variation at 40A from −40°C to +125°C - unlike TVS diodes which exhibit significant thermal drift.
