Product details
Overview
1.5SMC160H from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode rated for 1500W peak pulse power, 130V working stand-off voltage (VWM), and 230V maximum clamping voltage (VC) at 6.8A peak impulse current. It features glass passivated junction, AEC-Q101 qualification, and ISO 7637-2 compliance for automotive load-dump and surge immunity in DC power lines.
For engineers reviewing the 1.5SMC160H datasheet, 1.5SMC160H pinout, 1.5SMC160H application, or 1.5SMC160H equivalent, this device is selected for high-energy transient protection in 12V/24V automotive ECUs, industrial power supplies, and telecom interface circuits where fast response (<1.0 ps), low leakage (<1 µA @ 130V), and DO-214AB package compatibility are critical.
Technical Context
This TVS operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 144–176V breakdown range (VBR @ 1.0mA). Its thermal design supports 150°C max junction temperature with RθJC = 15°C/W and RθJA = 50°C/W, enabling reliable operation under sustained transients in enclosed enclosures.
The device meets ISO 7637-2 Pulse 1 (inductive switch-off), Pulse 2a/2b (battery disconnect/load dump), and Pulse 3a/3b (capacitive coupling) waveforms. Its 1.0ps typical response time ensures clamping before sensitive downstream ICs experience overvoltage stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before leakage exceeds 1 µA; defines safe DC bias margin in 12V/24V systems. |
| VBR min/max | 144 V / 176 V @ 1.0 mA - Breakdown voltage range confirming robust avalanche initiation across process variation and temperature. |
| VC @ IPPM | 230 V @ 6.8 A - Clamping voltage during 10/1000µs surge; limits downstream voltage stress to ≤230V under worst-case 1500W transient. |
| PPK | 1500 W - Peak pulse power rating per 10/1000µs waveform; enables protection against ISO 7637-2 Pulse 5a (load dump). |
| IR @ VWM | <1 µA - Reverse leakage at 130V; ensures negligible standby power loss and no interference with high-impedance sensing nodes. |
| TJ max | +150 °C - Maximum junction temperature; supports under-hood automotive placement without derating at 85°C ambient. |
| Package | DO-214AB (SMC) - Standardized surface-mount outline with 7.11 × 6.22 mm footprint and matte tin-plated leads for J-STD-002 solderability. |
Pinout & Package
DO-214AB (SMC) package: molded plastic case with cathode band marking; polarity-sensitive unidirectional configuration; terminals are anode (unmarked end) and cathode (banded end); weight ≈ 0.210 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or low-voltage rail; completes clamp path during reverse transient events. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., battery feed); conducts avalanche current into anode when VAK > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| ISO 7637-2 compliant | Guaranteed performance against all five standardized automotive transient pulses (Pulse 1, 2a, 2b, 3a, 3b) without external circuitry. |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives; supports MSL Level 1 handling. |
| Fast response time | <1.0 ps typical - Enables clamping before propagation delay of most microcontrollers and CAN transceivers. |
| Low clamping ratio | VC/VBR ≈ 1.39 (230V/165V typ) - Minimizes overvoltage overshoot relative to breakdown threshold, improving system margin. |
Applications
| Automotive Body Control Module (BCM) | Industrial 24V PLC I/O Port |
|---|---|
Use Scenario: Protecting LIN bus transceivers and microcontroller GPIOs from load-dump surges during alternator regulation faults. IC Role / Device Role: Unidirectional TVS placed between LIN line and chassis ground to clamp transients up to 1500W.

IC Role / Device Role: Standby clamp on secondary-side 48V rail to absorb residual transients escaping upstream filtering. Use Value: Withstands repeated 10/1000µs surges up to 1500W without degradation, extending Mean Time Between Failures (MTBF) beyond 10 years. |
Use Scenario: Protecting isolated gate driver ICs (e.g., Si823x) powered from 15V auxiliary supply in BLDC motor inverters. IC Role / Device Role: Clamp on gate driver VDD rail to suppress voltage spikes induced by high-di/dt switching currents in IGBT half-bridges. Use Value: 230V clamping ensures gate oxide integrity of 25V-rated drivers even during 600V bus transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Lower PPK (600W), higher VWM (130V), same DO-214AA package but smaller footprint (4.57 × 3.94 mm). | Not suitable for ISO 7637-2 Pulse 5a (load dump); limited to lower-energy transients in non-automotive 24V systems. | Select only if space-constrained and peak surge energy is ≤600W; verify layout clearance for reduced thermal mass. |
| 1.5KE130A | Higher PPK (1500W), axial-leaded DO-15 package, slower response (~1.5 ps), higher IR (5 µA @ VWM). | Requires through-hole mounting and manual assembly; unsuitable for automated SMT lines or high-density PCBs. | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required. |
Compared with 1.5SMC160H, SMBJ130A offers smaller size but insufficient energy handling for automotive load-dump, while 1.5KE130A matches power rating but lacks SMT compatibility and AEC-Q101 validation-making 1.5SMC160H the optimal choice for production automotive and industrial SMT applications.

FAQ
What is the maximum clamping voltage of the 1.5SMC160H under standard test conditions?
The 1.5SMC160H has a maximum clamping voltage (VC) of 230 V when subjected to its rated peak impulse current (IPPM) of 6.8 A using the 10/1000 µs waveform. This value is measured at TA = 25°C and guarantees that downstream components will not experience more than 230 V during a defined surge event, making the 1.5SMC160H suitable for protecting 150 V-rated circuits in automotive and industrial environments.
Is the 1.5SMC160H suitable for bidirectional transient protection?
No, the 1.5SMC160H is a unidirectional TVS diode intended for DC line protection with defined polarity (cathode marked). For bidirectional applications such as AC signal lines or differential buses, the 1.5SMC160AH variant must be used instead-it provides symmetrical clamping in both directions and is explicitly designated for bipolar use per TSC's ordering code conventions.
Does the 1.5SMC160H meet automotive qualification standards?
Yes, the 1.5SMC160H is AEC-Q101 qualified and tested to meet ISO 7637-2 requirements for Pulses 1, 2a, 2b, 3a, and 3b. Its construction-including glass passivated junction, MSL Level 1 moisture sensitivity, and matte tin-plated leads-ensures suitability for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is mandatory.
What is the thermal resistance profile of the 1.5SMC160H, and how does it affect PCB layout?
The 1.5SMC160H has a junction-to-case thermal resistance (RθJC) of 15°C/W and junction-to-ambient (RθJA) of 50°C/W. To maintain TJ ≤ 150°C under repetitive 1500W surges, PCB copper area under the cathode/anode pads should exceed 100 mm² per terminal with thermal vias to inner ground planes-this mitigates localized heating and ensures long-term reliability of the 1.5SMC160H in high-duty-cycle applications.
How does the 1.5SMC160H compare to the 1.5SMC160AH in terms of electrical performance?
The 1.5SMC160H (unidirectional) has VBR = 144–176 V and VWM = 130 V, while the 1.5SMC160AH (bidirectional) has identical VBR/VWM specs but operates symmetrically-clamping equally in forward and reverse bias. The 1.5SMC160AH also exhibits doubled IR limit for VWM ≤ 10 V (not applicable here), but both share the same 230 V clamping voltage, 1500 W rating, and DO-214AB package-making them functionally interchangeable only when polarity constraints allow.
