Product details
Overview
1.5SMC130CH from Taiwan Semiconductor is a unidirectional 1500W surface-mount transient voltage suppressor (TVS) diode with a breakdown voltage of 117–143 V, working stand-off voltage of 105 V, and clamping voltage of 187 V at 8.4 A peak pulse current. It features glass passivated junction, AEC-Q101 qualification, and ISO 7637-2 compliance for automotive load-dump and surge immunity.
For engineers reviewing the 1.5SMC130CH datasheet, 1.5SMC130CH pinout, 1.5SMC130CH application, or 1.5SMC130CH equivalent, this device is selected for high-energy transient protection in DC power rails, automotive ECUs, and industrial I/O interfaces where fast response (<1 ps), low leakage (<1 µA), and DO-214AB package compatibility are critical.
Technical Context
The 1.5SMC130CH operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 117–143 V breakdown range at 1 mA test current. Its 105 V working stand-off voltage ensures stable operation under nominal 12 V/24 V/48 V system rails with margin against ripple and tolerance drift.
Thermal performance is defined by RθJA = 50 °C/W and RθJC = 15 °C/W, supporting sustained dissipation up to 6.5 W at 25 °C ambient. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity for robust reflow assembly.

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Card |
|---|---|
Use Scenario: Protecting 12 V supply rail in BCM against load dump (ISO 7637-2 Pulse 5a) and alternator overshoot. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and local regulator input to clamp surges before LDO or DC-DC stage. Use Value: Limits voltage to ≤187 V during 1500 W transient, preventing damage to 36 V-rated input capacitors and enabling use of cost-optimized 25 V input regulators. | Use Scenario: Safeguarding 24 V digital input channels on PLC I/O module exposed to field wiring transients and ESD. IC Role / Device Role / Timing Role: Front-end protection element on each channel, mounted adjacent to connector to minimize inductance before optocoupler or Schmitt trigger input. Use Value: Sub-1 ps response ensures clamping occurs before 100 ns ESD events propagate into isolation barrier, preserving signal integrity and reducing false triggers. |
| Telecom Power Supply Input | EV Onboard Charger (OBC) Auxiliary Rail |
Use Scenario: Secondary-side transient suppression on +48 V telecom rectifier output feeding baseband processor and backplane logic. IC Role / Device Role / Timing Role: Standoff-rated TVS across 48 V bus to absorb coupled lightning surges (IEC 61000-4-5) and switching noise from adjacent converters. Use Value: 105 V VWM provides 10 % margin above 48 V nominal, while 187 V VC allows downstream 200 V-rated MOSFETs and capacitors to remain within safe operating area. | Use Scenario: Protecting 12 V auxiliary supply derived from OBC's high-voltage DC link, subject to coupling from 400–800 V switching edges. IC Role / Device Role / Timing Role: Bidirectional-capable variant not required; unidirectional 1.5SMC130CH used with correct polarity to clamp negative-going spikes on grounded-rail systems. Use Value: AEC-Q101 qualification and +150 °C TJ max ensure reliability in thermally constrained OBC enclosures where ambient reaches 105 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | 600 W rating, DO-214AA (SMB) package, lower PPK, same VBR range (117–143 V) | Not suitable for ISO 7637-2 Pulse 5a; limited to lower-energy transients like ESD or data-line surges | Select when board space is constrained and peak surge energy is ≤600 W |
| 1.5KE130A | Through-hole DO-15 package, 1500 W rating, identical VBR/VC, but no AEC-Q101 or ISO 7637-2 validation | Lacks automotive qualification; requires manual soldering or wave-solder process; unsuitable for under-hood deployment | Select only for non-automotive industrial or telecom applications where SMT is not required |
Compared with SMBJ130A and 1.5KE130A, the 1.5SMC130CH delivers automotive-grade reliability in an SMT package with full ISO 7637-2 coverage-making it the sole choice for AEC-compliant 12–48 V rail protection where both high pulse power and production scalability matter.

FAQ
What is the polarity configuration of the 1.5SMC130CH?
The 1.5SMC130CH is a unidirectional TVS diode, with cathode marked by a band on the DO-214AB package. It conducts only during reverse overvoltage events-forward voltage drop is 3.5 V at 50 A, per datasheet Note 2. This polarity enables precise placement on positive-rail protection paths without unintended forward conduction.
Does the 1.5SMC130CH meet automotive qualification standards?
Yes, the 1.5SMC130CH is AEC-Q101 qualified and explicitly validated for ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b. Its construction-including glass passivation, JESD201 Class 2 whisker resistance, and J-STD-020 Level 1 moisture sensitivity-ensures suitability for automotive under-hood and chassis-mounted applications.
What is the maximum clamping voltage of the 1.5SMC130CH under surge conditions?
The 1.5SMC130CH has a maximum clamping voltage (VC) of 187 V at 8.4 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across temperature and lifetime, defining the upper voltage limit imposed on protected circuits during worst-case transients.
Can the 1.5SMC130CH be used in bidirectional configurations?
No-the 1.5SMC130CH is unidirectional only. For bidirectional protection, Taiwan Semiconductor specifies the 1.5SMC130CAH variant (with "CAH" suffix), which uses dual-die construction and symmetric breakdown in both directions. Using 1.5SMC130CH in reverse-biased AC paths risks permanent failure.
What is the thermal resistance profile of the 1.5SMC130CH?
The 1.5SMC130CH has a junction-to-ambient thermal resistance (RθJA) of 50 °C/W and junction-to-case (RθJC) of 15 °C/W, measured under standard JEDEC PCB conditions. These values enable 6.5 W steady-state dissipation at 25 °C ambient and inform heatsinking decisions for high-duty-cycle surge environments.
