Product details
Overview
1K5SMPC13APH from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in TO-277A (SMPC4.6U) package, rated for 1500W peak pulse power (10/1000µs), 13.0V nominal breakdown voltage (VBR), and 18.2V maximum clamping voltage (VC) at 82.4A peak surge current - used for ESD and surge protection in automotive BLDC motor drives and battery management systems.
For engineers reviewing the 1K5SMPC13APH datasheet, 1K5SMPC13APH pinout, 1K5SMPC13APH application, or 1K5SMPC13APH equivalent, key selection criteria include unidirectional polarity, 11.1V stand-off voltage (VWM), 2.0µA max reverse leakage at VWM, 175°C junction temperature rating, and compliance with ISO 7637-2 (Pulse 1/2a/2b/3a/3b) and IEC 61000-4-2 Level 4.
Technical Context
This TVS diode operates as a unidirectional clamping device, activated when reverse voltage exceeds 12.4V (min VBR) and fully clamping at ≤18.2V up to 82.4A (IPPM). Its thermal design relies on low RθJL = 6.4°C/W and RθJC = 8.9°C/W, enabling effective heat transfer from junction to lead or case on standard PCB copper pads.
It meets AEC-Q101 stress testing requirements and supports automotive-grade reliability under transient conditions including ISO 10605 (L4), IEC 61000-4-2 (Level 4), and all five ISO 7637-2 pulses - Pulse 1 (inductive load dump), Pulse 2a/2b (supply line transients), and Pulse 3a/3b (switching noise).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 12.4 / 13.0 / 13.7 V - ensures reliable turn-on above system operating voltage while avoiding false triggering during normal 12V rail operation. |
| VWM | 11.1 V - maximum continuous reverse working voltage compatible with 12V automotive supply rails. |
| VC @ IPPM | 18.2 V - clamping voltage limits downstream IC stress during 82.4A surge events per 10/1000µs waveform. |
| PPPM | 1500 W - peak pulse power handling capacity for short-duration transients without failure. |
| IPPM | 82.4 A - maximum non-repetitive surge current capability defined at 10/1000µs waveform. |
| TJ max | +175°C - enables operation in high-temperature engine bay environments without derating. |
| αT | 0.072 %/°C - temperature coefficient of VBR used to calculate breakdown shift over junction temperature range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC package; lower PPPM = 400W; VC = 21.2V @ 19.9A; RθJA = 110°C/W | Limited to low-energy transients; unsuitable for ISO 7637-2 Pulse 1 or high-current motor drive protection. | Select only for cost-sensitive, non-automotive applications with <500W surge requirements. |
| 1.5KE13A | DO-201AD axial lead; PPPM = 1500W; VC = 20.8V @ 72.2A; not AEC-Q101 qualified | Requires through-hole mounting; lacks automotive qualification and ISO 7637-2 validation. | Acceptable for industrial SMPS where AEC-Q101 and surface-mount are not required. |

FAQ
What is the polarity configuration of the 1K5SMPC13APH?
The 1K5SMPC13APH is a unidirectional TVS diode, meaning it conducts only in reverse bias above its breakdown voltage (12.4–13.7V). It features two cathode terminals (pins 1 and 2) and one anode terminal (pin 3), enabling low-inductance, high-current clamping paths in automotive power circuits. This polarity prevents forward conduction during normal operation while providing precise overvoltage protection.
Does the 1K5SMPC13APH meet AEC-Q101 requirements?
Yes, the 1K5SMPC13APH is explicitly AEC-Q101 qualified per the manufacturer's documentation. It has passed stress tests including high-temperature operating life, temperature cycling, humidity bias HAST, and mechanical shock - confirming suitability for automotive under-hood and chassis-mounted applications where reliability is critical.
What is the maximum clamping voltage of the 1K5SMPC13APH at rated surge current?
The 1K5SMPC13APH has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 82.4 A, measured using the standardized 10/1000 µs waveform. This value ensures protected downstream components - such as 20V-rated gate drivers or ADC inputs - remain within safe operating limits during surge events.
Can the 1K5SMPC13APH be used in place of the 1K5SMPC12APH or 1K5SMPC15APH?
No - the 1K5SMPC13APH is not interchangeable with 1K5SMPC12APH or 1K5SMPC15APH due to distinct breakdown voltage ranges (12.4–13.7V vs. 11.4–12.6V or 14.3–15.8V). Substituting alters the clamping threshold and may cause premature conduction or insufficient protection. Each variant must be selected based on exact system VWM and VBR margin requirements.
What is the thermal resistance from junction to lead (RθJL) for the 1K5SMPC13APH?
The 1K5SMPC13APH has a typical junction-to-lead thermal resistance (RθJL) of 6.4°C/W, measured under standard test conditions (16 mm × 16 mm Cu pad). This low value enables efficient heat transfer from the silicon die to the PCB, supporting repeated surge events without thermal runaway in space-constrained automotive modules.
