Product details
Overview
1.5KE13A B0G from Taiwan Semiconductor is a unidirectional 1500W transient voltage suppressor (TVS) diode in DO-201 package, with nominal breakdown voltage 13V, minimum VBR = 12.4V at 1.0mA, maximum clamping voltage VC = 18.2V at 86A peak pulse current, and working stand-off voltage VWM = 11.1V - designed for automotive and industrial ESD/inductive load transient protection.
For engineers reviewing the 1.5KE13A B0G datasheet, 1.5KE13A B0G pinout, 1.5KE13A B0G application, or 1.5KE13A B0G equivalent, key selection criteria include clamping performance under ISO 7637-2 Pulse 1/2a/2b/3a/3b, unidirectional polarity marking, DO-201 mechanical compatibility, junction temperature range (−55°C to +175°C), and AEC-Q101 qualification status.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped overvoltage protection device, triggered when transient voltage exceeds its breakdown threshold (12.4–13.7V). It delivers 1500W peak pulse power handling at 10/1000μs waveform with sub-nanosecond response time (<1.0ps from 0V to VBR) and low dynamic impedance to limit voltage overshoot during fast transients.
It features a maximum forward voltage of 3.5V at 50A surge current (per JEDEC spec for VBR ≤ 200V), 1μA max leakage above 10V, and meets UL 94V-0 flammability rating in its DO-201 molded package - enabling robust integration into 12V automotive power rails and industrial control I/O lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR @ IT = 1.0mA | 12.4V min / 13.7V max - defines precise turn-on threshold for transient suppression in 12V systems |
| VWM | 11.1V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPP = 86A | 18.2V - clamped voltage seen by protected circuit during worst-case 1500W transient |
| PPK | 1500W - peak pulse power dissipation capability per 10/1000μs waveform per IEC 61000-4-5 |
| Junction Temp Range | −55°C to +175°C - supports under-hood automotive and high-temp industrial environments |
| Leakage @ VWM | <1μA - ensures minimal standby power loss and signal integrity in always-on circuits |
| Response Time | <1.0ps - enables effective suppression of ESD and fast-switching noise transients |
Pinout & Package
Package: DO-201 - axial-leaded, epoxy-molded case with cathode band marking for unidirectional polarity; UL 94V-0 rated; 0.090g weight; pure tin-plated leads compliant with J-STD-002 solderability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; forms cathode-to-anode clamping path during overvoltage |
| Cathode (banded end) | High-side transient input terminal | Connected to protected line (e.g., 12V supply); conducts surge current to ground when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified option available | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard |
| 1500W surge rating at 10/1000μs | Withstands high-energy transients per ISO 7637-2 Pulse 1 (inductive load dump) and Pulse 2b (battery disconnect) |
| Clamping voltage ≤18.2V at 86A | Keeps downstream 12V logic ICs and microcontrollers within safe absolute maximum ratings during surge events |
| Leakage <1μA above 10V | Minimizes quiescent current draw in battery-powered or energy-sensitive applications |
| DO-201 package with JESD201 Class 2 whisker resistance | Ensures long-term solder joint reliability in high-reliability industrial and automotive assemblies |
Applications
| Automotive Power Rail Protection | Industrial PLC Digital I/O Protection |
|---|---|
Use Scenario: Suppressing load-dump transients on 12V vehicle battery lines after alternator disconnection. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and ECUs to clamp voltage spikes up to 120V for <100ms.

IC Role / Device Role / Timing Role: Parallel-connected TVS across driver output to absorb inductive energy from long wiring harnesses. Use Value: Maintains LED string integrity by clamping transients before driver IC's internal FETs exceed VDSS limits. | Use Scenario: Adding secondary-level ESD protection on legacy USB 2.0 VBUS lines where primary TVS is absent or insufficient. IC Role / Device Role / Timing Role: Standalone unidirectional clamp referenced to ground, absorbing ±15kV contact discharge per IEC 61000-4-2. Use Value: Provides 1500W surge headroom beyond typical 300W USB port requirements, extending system robustness margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1.5KE13CA | Bidirectional variant; symmetric VBR = 12.4–13.7V; same PPK, VC, and DO-201 package | Required for AC-coupled or floating signal lines where polarity reversal occurs (e.g., RS-485, audio) | Select 1.5KE13CA only if bidirectional clamping is needed; 1.5KE13A B0G is optimal for DC rails with defined polarity. |
| SMBJ13A | Same VBR/VC specs but in smaller SMB (DO-214AA) package; lower PPK = 600W; surface-mount only | Suitable for space-constrained PCBs but not for high-energy automotive load-dump scenarios | Choose SMBJ13A for compact consumer electronics; retain 1.5KE13A B0G for 1500W industrial or automotive duty. |
Compared with 1.5KE13CA and SMBJ13A, the 1.5KE13A B0G uniquely combines 1500W surge capacity, axial DO-201 through-hole mounting, and AEC-Q101 qualification - making it the preferred choice for high-reliability 12V DC transient protection where layout flexibility and ruggedness are critical.

FAQ
What is the breakdown voltage tolerance of the 1.5KE13A B0G?
The 1.5KE13A B0G has a guaranteed breakdown voltage range of 12.4V to 13.7V at test current IT = 1.0mA, per Taiwan Semiconductor's official electrical specifications. This ±5.4% tolerance ensures consistent clamping behavior across production lots while maintaining compatibility with 12V system margins. The 1.5KE13A B0G achieves this via tightly controlled silicon doping and wafer-level screening.
Is the 1.5KE13A B0G RoHS and halogen-free compliant?
Yes, the 1.5KE13A B0G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in Taiwan Semiconductor's official documentation. Its molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This compliance supports environmentally regulated markets including EU automotive and industrial equipment.
Does the 1.5KE13A B0G meet ISO 7637-2 immunity standards?
Yes, the 1.5KE13A B0G is explicitly rated to meet ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test waveforms, as stated in Taiwan Semiconductor's product brief. Its 1500W peak pulse power and 18.2V clamping voltage enable full compliance when used with appropriate PCB layout (e.g., short traces, low-inductance grounding) - critical for automotive ECU design validation.
What is the maximum steady-state power dissipation of the 1.5KE13A B0G?
The 1.5KE13A B0G has a steady-state power dissipation (PD) of 5W at lead temperature TL = 75°C with 0.375" (9.5mm) lead length, per absolute maximum ratings. This value assumes copper pad mounting per JESD51-3; derating applies above 25°C ambient. Unlike its 1500W transient rating, this 5W limit governs continuous DC power handling - relevant only in fault conditions or sustained overvoltage.
How does the 1.5KE13A B0G differ from the non-A version (1.5KE13)?
The 1.5KE13A B0G has tighter VBR tolerance (12.4–13.7V vs. 11.7–14.3V for 1.5KE13), lower clamping voltage (18.2V vs. 19.0V at rated IPP), and improved consistency in leakage and temperature coefficient. The "A" suffix denotes enhanced parameter grading, while "B0G" indicates green compound and standard packing - both critical for automotive PPAP and industrial quality audits involving the 1.5KE13A B0G.
